10.0 RELAY INTERFACE
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. Also see section 3.4.3.
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.
