Relay Specifications
One side of each of the utilized input closures needs to be shorted to ground, pin 7, to create a
closure circuit. A rail voltage, pin 13, is supplied to pull up the other side of the input. The shield
is also a ground connection.
Input Closure Pin Numbers
Tie pins 8, 21, 11 and 24 to the pin 13 (rail voltage)
#1 – Pin 9 should short to ground (Pin 7) for a closure
#2 – Pin 22 should short to ground (Pin 7) for a closure
#3 – Pin 12 should short to ground (Pin 7) for a closure
#4 – Pin 25 should short to ground (Pin 7) for a closure
Output Relay Closures Pin Numbers
#1 – Pin 1 and 14
#2 – Pin 2 and 15
#3 – Pin 3 and 16
#4 – Pin 4 and 17
#5 – Pin 5 and 18 (reserved for Time Sync pulse)
#6 – Pin 6 and 19 (reserved for Alarm)
The time sync pulse settings are under the
settings section.
The alarm relay (#6) will close on the following conditions:
•
No Ethernet connection
•
No connection to the Internet and the AMB-OS server
are under the
submenu.
The output closures are Form A type closures and need a pull up to create the closure. You can
use the provided rail voltage on Pin 13.
The following diagram shows the use of a +12V external pull-up source. Pin 13 is not connected
to anything and the +12V source connects to pins 24, 11, 21 and 8.
