1. Introduction
The tM-AD8C is an current input module that includes 8 single-ended analog input
channels and provides a programmable input range on all analog inputs (0 ~ 20 mA, 4 ~
20 mA). The sampling rate of the tM-AD8C is adjustable and is available in either fast or
normal mode and It also provides 4 KV ESD protection as well as 2500 Vrms intra-
module isolation.

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.
4. Default Settings
Default settings for the tM AD modules are as follows:
。 Protocol: Modbus RTU
。 Module Address: 01
。 Analog Input Type: type code 08, -10V to 10V
。 Baud Rate: 9600 bps
