The safety module in the MS-ER MA R01 series is a logical block, with an integrated actuation unit, that can be used to implement electrical control systems associated with the functional safety of a machine.
Typical applications are the control of Emergency Stop controls - Limit switches for mobile safety guards - Safety Sensors and Devices with solid-state outputs such as photo-electric Safety Curtains (ESPE). By connecting these devices appropriately to the inputs of the safety module, 2-channel control systems with integrity levels up to SIL "3" may be implemented according to EN 62061 or IEC 62061 with performance levels up to PL"e" according EN ISO13849-1.
Single-channel circuits can also be implemented but with integrity levels up to SIL"1" and performance characteristics to PL "c" levels. The module is also equipped with a dedicated START input, which when appropriately configured, allows for the implementation of AUTOMATIC START or MANUAL START functions.
