Combination I/O Modules 8-1

Combination I/O Modules 8

Note: It is not necessary to recalibrate analog I/O if a logic module is replaced.

Analog logic modules may be hot swapped and will not require recalibration. User calibration data is stored

in system memory outside of the analog module. Factory calibration data is stored in memory in the plug-in

logic module. Since all logic modules are calibrated to the same factory standards, recalibration is not

necessary if logic modules are moved or replaced.

Combined Discrete Input and Output Module

Overview

This module combines four discrete inputs and four discrete outputs. An input count feature uses analog

input registers to accumulate the positive transitions of each input. Each of the four outputs may optionally

be configured as Time Proportioned Outputs that pulse ON at a duty cycle proportional to an analog output

Number of Discrete Inputs 4

Input Voltage Range 10 - 30 VDC/VAC

Number of Discrete Outputs 4

Max. Load per Output 1 Amp

Max. Inrush Current 5 Amps (for 100 mS)

Wiring

A pair of floating terminals is provided for each input to provide channel-to-channel isolation and

a choice of sourcing (power switching), sinking (ground switching) or AC signals on each input. The

outputs all switch power from the DC power input terminal. A ground return for each output

is provided for your convenience.
