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.
