DELCON Series Interface Relays for Demanding Industrial Applications

Pulse transformer technology for isolating I/O signals offers significant advantages over optical isolation and electromechanical relays. Most notably, pulse transformer I/O modules provide higher transient immunity and high input-to-output isolation. The high transient immunity means the Weidmuller - Delcon I/O modules are ideal for I/O applications where electrical noise is a problem. No additional suppression components are needed even when used with long unshielded signal cables, inductive loads or ‘noisy’ power lines. The limitations of optocoupler based solid-state relays disappear when pulse transformer I/O modules are used. For instance, the standard AC output module SLO 24TR has near zero leakage current; requires no minimum load; can be used with any power factor 0 to 1; is rated for both general use and inductive loads at 3A; and is immune to both load line and signal line spikes. Features: • virtually no off-state leakage currents • high current and high voltage D

SMVector Drives for Pumping Applications

No challenge is too great or single application too small. From industrial plants to OEMs to municipal water and wastewater treatment facilities, Lenze pump solutions are hard at work. Versatile and robust, our industrial drives and controls are cost-effective and low-maintenance. Our focus is on variable speed flow and pressure control so whatever your specific application requires, Lenze has the drives and controls to match form, fit and function. Centrifugal pumps Centrifugal, or Variable Torque pumps, are used in a wide range of commercial, industrial and municipal applications. Throttling valves are a common flow control method. Compared to a throttling valve, the lower power requirements of the SMVector VFD provide a greater energy savings. Operating at 75% flow reduces power demand by over 50% with an SMVector Drive, while a throttling valve requires about 90%. Typical applications •Chilled and Hot Water Pumps •Condenser Water Pumps •Booster Pumps •Potable Water Pum

SAFESERIES SIL Relays - Functional Safety for Process Applications

When dealing with the core elements of a system with a large risk potential, it is especially critical to have the best system solution in place. Our SIL relays reliably switch off your systems in critical situations – and they have all been accredited. Let's connect. Whether for a burner control system, secure emergency shut down or, for example, for pump controllers – our safety relay guarantees safe conditions and encompasses highly superior and significant features. Their integration into distributed control systems (DCSs) is even better, with an input filter which makes the SIL circuit immune to the test impulse which is typically used by a DCS. You will also benefit from simple maintenance: the fuses are accessible from the outside and can easily be changed. You can see the status of the safety a

Industrial Relay Module with the Proven Connection Technology

Weidmüller‘s relay bases are remarkable for their secure connection systems and their ease of use during wiring and installation. Pluggable cross-connection and the extra-quick PUSH IN connection help you to further reduce wiring times. In combination with the established relay technology, our industrial relay modules provide users with excellent reliability and service convenience. The wide range of relay modules provides the right solution for every industrial application. The RIDER SERIES and its RCI, RCM, RRD and RPW product lines have been successfully integrated into the entire Weidmüller line of relay products. This modular-designed product series formally complies with international standards. A variety of pluggable versions are available with from one to four CO contacts and your choice of connection method. Our innovative relay bases with PUSH IN connection systems are available for both the RCI/RCL and RCM product lines. PUSH IN technology is safe and easy to use and

Weidmuller MCZ SERIES Relays and Solid-State Relays

A special feature of the MCZ SERIES is its low profile shape. With a width of only 6 mm, it is particularly well suited for decentralized usage in sub-distribution boards and terminal boxes. You can reduce the installation time by 50 % compared to conventional methods when you use the tension clamp connection and the ZQV 4N pluggable cross-connection on three voltage potential points. The MCZ TRAK components, which have been developed for the rail industry to comply with the requirements of EN 50155 and EN 61373, are a special highlight. All components have been specially designed to function reliably in temperatures ranging from -40 to +70 °C (and +85 °C for ten minutes). The MCZ TRAK components feature a painted switching element that protects it from condensation which

Short-Circuit-Proof Switching Amplifier for Inductive Loads up to 10 A

The MICROOPTO family offers the customer high-quality optos and solid-state relays for application-oriented problem solutions. All products are designed in the space-saving 6 mm terminal size. The new solid-state relay can be connected in the output circuits of control systems and feedback control modules for selective activation of inductive loads up to 24 V DC/10 A, such as solenoid valves, contactors etc. The error controlled output monitors short-circuts and, if necessary, switched off; a potential-free signalling contact provides feedback to the control system – the system can be shut down in a controlled manner for error rectification. The powerful output of the MICROOPTO SOLENOID switches 10 A at 55 °C. The product can be used worldwide thanks to international approv

No-Wear Isolation of Potentials in Terminal Block Design

The TERMOPTO opto modules are characterised by a particularly compact design, pluggable cross-connections and an optimal price-performance ratio. TERMOPTO offers a compact, electronic alternative to the electromechanical relay for electrical isolation and signal conditioning. Instead of an electromechanical solution that is susceptible to wear, a maintenance-free and compact terminal block with integrated electrical isolation is used. This saves space, reduces the amount of servicing and increases system availability. In addition, the overall accessory needs are reduced, because cross-connectors and markers from the terminal portfolio can be used. Compact design reduces space requirements in the switching cabinet by > 80 % compared to conventional relay solutions. We

Weidmuller TERMSERIES Relays and Solid-State Relays for All Purposes

Weidmuller’s TERMSERIES offers innovative pluggable electromechanical and solid-state relays equipped with one or two changeover contacts housed in a slim 6.4 mm or 12.8 mm design with matching profiles that can be combined as required in the customer’s application and reliably switch loads of up to 8A at 250V. Depending on the application customers can choose between products with a fixed voltage input or Weidmuller’s unique multi-voltage input which allows conditioning signals from 24V up to 230V AC/DC with just one module. A distinctive status display is available through integrated fiber-optic technology that completely illuminates the ejector. The ejector also ensures the safe removal of the switching element. The versions with single and dual changeover contacts as well as screw clamp and tension clamp terminals have the same profile and can be jumpered with each other with easy to use cross connectors. Well thought out accessories such as isolation plates used to visib
