Introduction

1.8Optional Expansion Board Overview

The Universal Monitor Expansion Board, purchased separately, has connectors for 16 digital inputs and eight digital outputs, as shown below. The board has light emitting diodes (LEDs) to display the status of monitored output devices, communications ports for connection to the Universal Monitor, power connections and other features necessary to monitor and protect your operation.

J - 24VAC power connector

I - Power status LED (green)

H - EIA485 connector

G - EIA485 status LEDs (yellow & red)

F - General status LED (green)

USE COPPER (CU) CONDUCTORS ONLY.
