The PSR-TRISAFE is the new safety controller from Phoenix Contact. A single TRISAFE controller can monitor an entire safety circuit, from emergency stops to safety doors, in a machine or plant.
The slim 67.5 mm safety controller can monitor up to 20 safety input signals. For example, the TRISAFE can monitor up to 10 dual contact emergency stops. It also provides four safety category 4 outputs with ground switching option and 4 additional non-safe general purpose outputs.
