7.11.11 RL-378 Optional I/O Expansion Board with 240V Relays, Continued.
Remote Alarm Inputs
There are 7 alarm inputs on the RL-378. Each can be individually DIP switch selected for
either digital or analogue mode. In digital mode, standard open circuit and closed circuit
conditions are expected. In the analogue mode, a normal input state requires a total
loop resistance of 10KΩ. The DIP switch settings are as follows.
The MAXPRO-Net software allows these remote alarm inputs to be utilized in exactly the
same way, as are those from a RD-400 alarm input card.
The alarm test facility (SW1-8) automatically echoes the current alarm input state back
out the relay outputs. Using the output LEDs the alarm input can be locally tested and
verified. Alarm inputs 1→7 are echoed to relay outputs 1→7. The tamper input on the
RD-378 is echoed to relay output 8. Note that this test facility should be disabled during
normal system operation.
Manual Iris Control
This output provides +ve and –ve voltages for manual iris control. This output is from
PL12 on the RL-378 board. There are 2 links associated with this output that select
between 6 volt or 12 volt iris motors.

These link positions do not affect the zoom or focus motor voltages.
