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)

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

Connections

Max. 10 V

Max. 2.5 mA / AO
