Phoenix Contact PSR Series Input/Output Module, 4 Inputs, 4 Outputs, 24 V

The Phoenix Contact safe extension module provides the system additional safe outputs as well as signal outputs. It makes it possible to cost-effectively implement small applications with three safety functions as well as applications with up to 160 I/Os. In addition to monitoring classic safety functions, such as emergency stop signals, safety door locks, light grids, and safety shut-off mats, safety functions such as speed, zero-speed, or direction of rotation and safe analog value monitoring can also be implemented. The system is intended for machines and process applications up to PL e or SIL 3.
