Introduction
The IL-A42 OEM induction loop module is part of Contacta’s induction loop system range. It has been designed to
be incorporated into third party manufacturers’ equipment. It allows an easy integral solution to machines and
equipment requiring an induction loop. The unit is low profile, discreet and can be fitted in small confined spaces.
There is no setup required. The unit is “plug and play”. It is supplied as a bare board but a suitable housing is
available separately.

Safety Precautions
Installation by a qualified engineer is strongly recommended
Ensure that you use a Contacta PS-55-00 power supply or a suitable power supply with a rating of 12-
14volts 2 amps peak. Do not attempt to plug it in to any other device otherwise damage may occur.
Do not attempt to dismantle or modify any parts of the unit. No user serviceable fuses or parts are included.
Warranty may be void if you do so. For repair, consult a Contacta engineer

Power Supply
• We recommend the unit is powered using a CA-10-02 Power
Supply through port J1. If using a host system, ensure it meets the
following specifications:
•
Supply voltage: 14V DC
•
Current output: 2A minumum
•
2.1mm power connector jack
•
J1 is a 2.1mm DC jack with centre pin positive.
Audio Input Connection
•
J2 is an audio input connection [100V line].
• J2 and J3 are connected in parallel and are therefore
interchangeable. They are ohmically ground isolated and have
series resistance to prevent interaction due to the paralleling of
stereo channels within the system.
