Nextek USB A/1394 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 unauthorised 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
