Configurable shutdown and speed monitoring for functional safety
01 June 2012
Monitoring safe shutdowns and the movement of drive components is easier with the PSR Motionstop safety module from Phoenix Contact. Standard incremental encoders, safety, certified SIL rotary encoders, and proximity switches can be connected to the 35mm wide device, thereby implementing important safety functions in accordance with EN 61800-5-2. Semiconductor and relay outputs quickly and safely stop dangerous movements if necessary.
Up to four different operating modes can be monitored for one machine in connection with external drive components, and the integrated STO (safe torque off), SLS (safely limited speed), SMS (safe speed management), and SDI (safely monitored direction) safety features.
The safety module is easily configured with the removable PSR-OP service and display unit. This is not required for the basic device to function, meaning that a remotely operated PSR OP unit has maximum protection from manipulation and offers cost advantages over the use of several basic devices. The safety module is suitable for applications up to SIL 3 in accordance with EN 61508 and EN IEC 62061, and PLe in accordance with EN ISO 13849-1.
