10.0 RELAY
INTERFACE
The AE 403 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.
Contact Adam Equipment or your supplier for a relay interface that is compatible with the
relay drivers, however other interfaces can be used as long as the following conditions
apply.
Connections to the drivers:
Connections are made to the PCB, Connector P1. The connector is a spring activated
type, simply press on the top of the connector and insert the wire.
Do not exceed the safe limits of voltage or current of 24VDC or 15ma per output.
Depending upon the application it may be necessary to use a small relay to drive larger
relays, or to provide additional protection to prevent electromagnetic interference (diodes
as shown above) to this or other machinery.
