1. Introduction
The tM-AD4P2C2 is a multifunction module that includes 4 analog input channels, 2
digital input channels and 2 digital output channels. The module provides a
programmable analog input range that includes 2 voltage input channels (±1 V, ±2.5 V,
±5 V, and ±10 V) and 2 current input channels (±20 mA, 0 ~ 20 mA and 4 ~ 20 mA).
The analog inputs provide a high overvoltage protection of 120 VDC and an adjustable
sampling rate. The module supports sink-type digital output with short circuit protection
and the digital outputs can be used as voltage input limit alarms. The digital inputs are
source-type and all digital 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 2500 VDC intra-module isolation are also provided. The tM-AD4P2C2 supports the
DCON, Modbus RTU and Modbus ASCII protocols, which can be configured via
software.

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.
