PointScan/122

16 Discrete Inputs

Overview

This module provides sixteen input channels. Inputs may be wired as all sourcing or sinking. An input

count feature uses analog input registers to accumulate the positive transitions of each input. More

information on this and other features can be found in the on-line help supplied with

the IO Toolkit program.

Number of Channels 16 discrete inputs (connected to a common source)

Input Voltage Range 12/24 VDC/VAC

Input Current @ 24 VDC 6.7 mA

Wiring and Jumpers

Positive DC or AC voltage must be applied to an input to indicate an ON condition. All channels are

referenced to a common return or supply, which is connected to the negative side (ground) or positive side

(DC+) of the DC power source. One wire from each sourcing field input should be bussed together and

connected to terminal 17 (DC +). One wire from each sinking field input should be bussed together and

connected to terminal 18 (DC GND). Refer to the wiring diagram below. Set jumper W1 to match the

wiring configuration of the inputs.
