Extension module 4AI + 4AO

AK-XM 103A

ADAP-KOOL® Refrigeration control systems

Introduction

Application

The extension module should be used with a controller in the same serial connection if there is not enough connections on the controller itself.

Function

The module contains:

•4 analog inputs for temperature sensors, pressure transmitters, voltage signals and contact signals.

•Four analogue outputs (0-10 V) for speed control of e.g. frequency converters

Installation

•The module is connected to the plug from the previous module in the sequence.

Supply voltage

The supply voltage to the module comes from the previous module in the row.

Supply voltage to a pressure transmitter can be taken from either the 5 V output or the 12 V output depending on transmitter type.

Light-emitting diodes

Only the two top LED’s are used. They indicate the following:

•Voltage supply to the module

•Communication with the controller is active (red = error)

Connections

Galvanic isolation

There are three groups, and the signals should not be mixed up:

•Inputs and 5V and 12V supplies for the signals connected to the inputs.

•Output 1 and 2

•Output 3 and 4

Max. 10 V

Max. 2.5 mA / AO
