32 Point DC Digital Input
Step
1
ATTENTION: RTP and cables are intended for permanent installation within their own enclosure.
Mount RTP cable assembly to HC900 Controller (Figure 92).
•
Remove appropriate key tabs from terminal board to allow mating with the module. See page 75.
•
Connect terminal block end of desired cable assembly to 32 point Digital Input module at controller.
Choose from:
900RTC-3210
900RTC-3225
•
Install 32 point DC DI label into the module connector cover.
•
Connect both shield drain wires to the grounding bars at the base of the HC900 rack. All field-wiring
shields must be grounded as described in the shield grounding section (page 70).
2
Mount RTPs to DIN rail.
•
Latch to rail. See page 244.
•
Connect cables to RTPs. Cables are marked "RTP A" and "RTP B." In step 4, RTP A will be wired to
Inputs 1-16, RTP B to Inputs 17-32. You can write on the RTPs' labels to distinguish them.
3
Set/verify jumper positions on each RTP as shown.
Module Removal / Insertion Under Power (RIUP) is supported by turning off Switch SW1 to allow removal of
the module from the rack without causing an arc. See page 73.
See page 242 for RTP internal schematic.
