Safety: Modular Controller

Dec. 1, 2011
The PSR-TRISAFE/M modular safety controller makes it easy to expand I/O in a safety circuit.

It connects up to 10 safe digital I/O modules, thanks to a T-bus system. The base station has 20 safety input signals and four safety category 4 outputs, like the original TRISAFE/S (standalone). It also provides outputs for a test pulse, alarm (aux), and ground switching. The safe digital I/O module can be configured as either 12 safe digital inputs, or eight safe digital inputs and four safe digital outputs. Each point on the safe expansion module can be controlled individually. It uses the “Safe Configure,” or SAFECONF configuration software with drag-and-drop technology that requires no programming. SAFECONF simulation mode allows testing of the safety design even without connecting the hardware.
