Safety-M Compact Series Safety Modules
Kübler announced its Safety-M compact series safety module for speed monitoring where space is limited. The removable operating and diagnostic display stands for easy parameterizing. The safe inputs and outputs and the integrated signal splitter allow its integration in existing safety circuits.
The Safety-M compact series safety module provides a cost-effective means for retrofitting older machines to they meet Machinery Directive 2006/42/EC requirements.
The integrated signal splitter for the encoder signals saves expensive and complex external wiring. Moreover, the easy forwarding to a control system or frequency converter is ensured.
The safety module firmware integrates comprehensive speed and position-related safety functions for drive monitoring according to EN 61800-5-2 (e.g. SS1, SS2, SOS, SLS, SDI, SSM). The extensive diagnostic function integrated in the firmware allows achieving, with a certified encoder, the safety level SIL3/PLe.
The encoder interface supports SinCos, TTL / RS422 and HTL / push-pull and proximity switches. Up to two safe encoder connections can be achieved per axis.
4/2 safe inputs and 8/4 safe shut-off channels are available. The analog output ranges from 4 … 20mA and provides a fast internal speed signal conversion.
There is also a removable OLED touch screen with plain text display offered as an accessory. It allows performing local diagnostics and parameterizing without PC software. The status LED on the front side indicates the operating status of the module.
Contact multiplication or contact reinforcement by means of external contactors combined with integrated cross short-cut monitoring (EDM) is possible. The device is easy to mount on a 35 mm C profile rail.
