The tM-P3R3 provides 3 channels for digital input and 3 channels for relay output, each of which features photocouple isolation. All output channels are form A type relays, while input is based on sink- or souce-type using a wire connecion. All input channels can be used an 16-bit counters. There are options for configuring power-on and safe digital output values. 4 kV ESD protection and 3750 VDC intra-module isolation are also provided
