4.5 Installing a 635-Model Output Relay Board
If you are not installing a Relay Board, skip this section.
Notice: if you are upgrading a 500-model ORM, this is the solution you will use.
NOTICE: The Relay Board can install in a single layer in the cabinet, or you can use a stacking kit which is available
from the Galaxy Product Catalog. One stacking kit allows you to stack 2 Boards onto 4 panel studs..
635-OUTPUT RELAY BOARD - FEATURES
Binary Dipswitch (SW1):
is a
4-position switch

Power Input (J1)
+12V on PIN-1 from Dedicated Power Supply; use separate Power Supply (not the one powering the DSI).
PWR LED
indicates board is connected to the power harness and the power is on (solid/on).
RS-485 Connection (J2)
for RS-485 3-Wire (D+, D-, GND) PIN-1 = D+; PIN-2 = D-; PIN-3 = GND.
REC LED
indicates board is receiving data over the RS-485 network connection (flicker/blinking = data receiving).
XMT LED
indicates board is transmitting data over the RS-485 network connection (flicker/blinking = data transmitting).
RELAYS (RY-1, 2, 3, 4, 5, 6, 7, 8)
there are eight Form-C SPDT Dry Relays, (Rated max. 24v, 1.5 Amps). These relays can be
wired Normally Closed (NC) or Normally Open (NO) to an output device.
OUTPUT LEDs (D1, 2, 3, 4, 5, 6, 7, 8)
indicates when a relay is active/engaged (regardless of how it is wired (NO/NC)).
