PSR-TRISAFE-S Safety Controller
The PSR-TRISAFE-S is a standalone safety controller with 20 safe inputs, four safe outputs and two safe ground-switching outputs
If additional safe outputs or safe relay outputs are needed, standard safety relay expansion modules can be hard-wired to the safe outputs of the PSR-TRISAFE-S module
System designers should consider adding a safety expansion relay for one of two reasons： （a） the PSR-TRISAFE-S module does not have enough safe outputs; （b） a safe relay circuit is needed to switch a voltage other than 24 Vdc
The PSR-TRISAFE-S module is a 24 V solid-state device
Intuitive three step software Manipulation proof： Password protect against unathorised changes in the safety logic of the hardware and software： Protect against unwanted changes in the safety logic with the front of device "CONFIRM" button All commonly used safety functions can be implemented easily and flexibly： E-stop and guard door monitoring, non-contact switches, safety sensors, laser scanners, optical devices （with or without muting） as well as safe mode selection, enabling switches, two hand control devices 2 clock outputs, 4 alarm outputs and ground switching output to increase safety of monitoring circuit
