635/600 DRM (DPI) Description:
See Appendix M for complete component list of 600 DPI
The DRM (DPI) Board controls the readers, door contacts, request to exit, door lock, and offers an
additional output relay for both reader/door ports. 600 and 635 DPI’s are interchangeably
compatible with either a 635 or 600-series CPU.
635-DRM WARNING – Do not connect a 5v Reader directly to a 635-DRM.
You must install a 5-VDC
voltage regulator in line – preferably at the reader end.
635-DRM NOTICE – See Appendix-Q
of this guide
for installation instructions including wiring
Lock Relays for wet relay operation
.
•
Controls two (2) Reader ports (sections) per board
, including contacts for Door Contacts, REX devices.
•
Controls two (2) Lock Relays per board
(one relay per reader port/section); Form C SPDT DRY RELAY.
»
600/635 Lock Relays support either Fail-safe or Fail-secure wiring; Dry relay Fail-safe or Fail-
secure wiring is shown in Chapter 2 (see 600 DPI board layout in Appendix M;). All 635 Wet Relay
wiring is shown in Appendix Q).
»
600/635 Lock Relays a support Dry Relay operation by default,
»
635 only supports wet relay operation for Lock Relays; wet/dry operation is independent per
section. See Appendix Q for 635 instructions.
•
Controls two (2) Output Relays per board
(one relay per port/section); Form C SPDT DRY RELAY. Relay-2
supports either Normally Open or Normally Closed device wiring.
•
LEDs are provided on the edge of board to indicate when a Relay is activated (LED = solid on) or deactivated
(LED = off).

600 DIO Detailed Description:
See Appendix M for complete component list of 600 DIO
The DIO Board
controls eight (8) input devices and four (4) output devices per board.
The board comes with
built-in supervision and Hypervision capability that is turned on from the System Galaxy software after end-
of-line supervision resistors have been installed. The Output Relays are
Dry Form-C SPDT relays that can
be wired Normally Open or Normally Closed based on they type of device being used (see diagram of DIO
in Appendix M).
