Do-more T1H Series PLC System Components
The Do-more T1H Series CPU modules were designed for use with the Terminator I/O
product line. For those not familiar with Terminator I/O, it is a modular system which
combines the functions of terminal blocks and I/O modules for distributed I/O. Each
Terminator I/O system contains: a Power Supply, a Base Controller, and one or more
I/O Module(s). Now with the addition of the T1H CPU, standing in place of the Base
Controller, the Terminator distributed I/O system becomes a complete, highly functional,
stand-alone PLC system.

Power Supplies
120/240 VAC and 12/24 VDC power supplies are available. The AC version has a built-in
24 VDC supply. A power supply must be the leftmost component in a slave system followed
by the CPU. Additional power supplies should be added between I/O modules to meet
power budget requirements.
I/O Modules
A Terminator I/O module assembly consists of an I/O module and a separate base, as shown
below. A complete range of discrete modules which support 12/24 VDC, 110/220 VAC and
up to 7A relay outputs is offered. The analog I/O modules provide 12 and 14 bit resolution
and several selections of I/O signal ranges (including bipolar). The temperature input
modules provide 16 bit resolution with several temperature input range selections.
