Assembly
Install the module into the protective housing as shown in
Figure 1. Connecting cables should be fed through the cable
entry hole at the rear of the protective housing before the
module is fixed into place.

Wiring
Connect the I/O module to the loop via the COM2 (positive)
and COM1 (negative) inputs.
Inputs A to D each require an end-of-line resistor (150KΩ, 5%,
1/4W). Inputs are supervised for open circuit (ON/OFF) or
short circuit (ON/OFF) status. For a fully supervised input
(open and short circuit) an additional resistor (33KΩ, 5%,
1/4W) must be installed as shown in Figure 3.

Open circuit - 555KΩ
243KΩ - 54KΩ
39KΩ – 11KΩ
5.6KΩ – short circuit
* 150KΩ EOL included
Addressing
Each module must be assigned an address from 1 to 128. Use
the rotary dial marked 0 to 12 to set the tens and hundreds part
of the address, and the rotary dial marked 0 to 9 for the
remaining digits. See Figure 4 for sample address settings.
Note:
To overcome the mechanical effects of shipping and
storage, we recommend that you first rotate each dial counter-
clockwise (to the 0 position) and then clockwise (to the dial's
maximum position) before setting the required address.
Maintenance
Basic maintenance consists of a yearly inspection. Do not
modify internal wiring or circuitry.
