Kuebler SMC2 is a compact safety module of the Safety-M family with integrated drive monitoring for one axis with 2 encoder sytems. This standalone speed controller (basic module) can be operated without additional safe PLC. Safety-M compact is the optimal solution for integration in existing safety circuits or for retrofitting old machines. Two encoder solutions (HTL/proximity switch, TTL/RS422, SinCos) are supported for safe speed acquisition.
