Adam Equipment
AE RELAY ACCESSORY
(P.N. 3106611295), Revision A, June 2011)

CAUTION
The relay accessory is designed to allow the AE402
indicator to connect to user equipment. High voltage connections
can be made to the relay PCB.
WARNING! All electrical installation and maintenance
work should be carried out by qualified electricians only.
WARNING! Do not attempt any work with power applied.
Switch off the mains. It is good practice to check (with a voltage
indicating instrument) that the power is off before beginning work.
ANGEROUS VOLTAGES may be present. Only qualified
personal should attempt the connection of the relay to user equipment
ANGEROUS VOLTAGES can cause physical injury and/or
damage to the equip
I

INSTALLATION
The AE 402 indicator is supplied with drivers to control external relays.
The drivers could be used to control a number of different relays
depending upon the users need. The relay drivers are isolated outputs
requiring the use of an external power supply for the relays.
The Relay Accessory is a product to allow quick and convenient
connections to the AE402 for control of external equipment or
indicators.
Connections to the AE042 are made at terminal strip P1:
Within the AE402 the output to drive external relays is on the circuit
board inside the enclosure. To gain access you must remove the 6
screws securing the front to the rear of the case. Pass the wires for the
relays through the grommet on the rear panel. The wires will connect
to the PCB using the terminal strip P1. See the AE402 User manual for
more details.
Any of the 4 relays can be connected to any of the 4 outputs. The
+12Vdc from the relays connects to the Common terminal.

POWER SUPPLY
Power for the relays can come from a user supplied source. 2
Alternative power input points are provided depending upon the power
the user has available.
Connector VAC is used for 15-25V C or 12-20VAC, 50/60Hz. 500ma.
This input is not sensitive to polarity, either terminal can be used.
If the user has 12V C to 15V C, 500ma available then connector marked
12V c can be used. Be careful with the polarity, using +12 to 12V and
minus voltage to the GN terminal.
Only one power input terminal should be used at one time
OPERATION
uring operation the relays will be active at the same time the
Low/OK/High LE s on the front panel operate and the Zero relay is
activated when the scale is at zero point.
Note the scale must show a small weight before the LOW LE will
activate. See the AE402 User Manual for details of how to set the limits.
User connections to the relays are made using the terminal strips
marked OUT1 to OUT4. The relay active for each LE will depend on the
input connection, Input IN1 controls relay 1, OUT1 for example. But IN1
could be connected to any of the 4 terminals in the AE 402.
CAUTION:
The voltage and current limits of the relay outputs must be less than:
115/230VAC, 1amp or 24V C. 1amp.
Higher currents may damage the circuit board.
The relays are not specified for higher voltages.
