Introduction
The tM-P3R3 provides 3 channels for digital input and 3 channels for relay output, each of which features photocoupler isolation. All output channels are Form A-type relays, while the digital input channels can be configured as either sink- or source-type through wiring. All input channels can be used as 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.
