Switching device SAE-41-312-A for 8,2 kOhm Safety edges and Bumpers in Polycarbonate housing

The SAE 41-312 switching device is used to evaluate sensors such as safety contact mats, safety contact strips and safety bumpers for securing crush and shear locations. An ASO sensor can be connected to the switching device. The steady-state current monitoring of the sensor is made possible by an integrated terminating resistor in the sensor. If the desired steady-state current flows, the safety relays are driven and the switching contacts closed. If the sensor is operated or the sensor circuit is interrupted, the relay switching contacts open. A signal output with potential-free switching contacts is available. An operation of the sensor causes a reaction of the signal output in accordance with the DIP switch configuration. The signal output must not execute any safety-orientated functions. It is not fail-safe and not checked by testing either. The switching device has been designed and type-approved in accordance with EN ISO 13849-1 “Safetyrelated parts of control systems” for category 3 Performance Level e. For compliance with category 3, the safety output is set up redundantly with two independent switching elements. In addition the device has been type-approved according to EN 62061 “Functional safety of safety-related electrical, electronic and programmable electronic control systems“ and can meet a safety function up to SIL 3 . The monitoring state of the sensor and the applied operating voltage are indicated by LED. If there is a fault alarm, all safety outputs are inactive.

Intended use:
The switching device can only fulfill its safety-relevant task, if it is used as intended within specifications. The intended use of the switching device is the use as a protection system in connection with safety contact mats, safety bumpers and safety contact edges with 8.2 kΩ resistance for steady-state current monitoring. A different use or any use going beyond the intended use is not within specifications. The manufacturer does not accept any liability for any damage arising from use not within specifications. Any use for special applications requires prior release by the manufacturer.
