10.8 Field Wiring 635-DRM Remote Door Module to the 635 DSI Multidrop
Figure 60 – Wiring a 635-DRM (for Remote Door Modules) to a 635-DSI Board:
The DSI BOARD is shown
component-side up
(typically, it installs component-side down) – keep this in mind when
you are landing wires. When board is facing down, Terminal “A” is next to the LED. Section-1 is closest to the power
wiring harness in the controller. See Step-4 of this Chapter-2.

MAX DOORS VS. BOARDS:
Supports up to
16 DRM boards
per DSI Section
(up to 16 DOORS per section)
Note you can have 1 or 2 doors
attached to a DRM so this will
affect the number of DRMs you
need.
See instructions that come with
the Remote Door Module.
See Step-4 for help with setting dipswitches (board ID) and Appendix O for how relays are assigned.
