1. Introduction
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.

3. Block/ Wiring Diagram
•Use 26-12 AWG wire for signal
connections.
•Strip the wire to a length of
7±0.5mm.
•Use a crimp terminal for wiring.
•Avoid high-voltage cables and
power equipment as much as
possible.
•For RS-485 communication, use
insulated and twisted pair 24 AWG
wire, e.g. Belden 9841.
