16 Point DC Digital Input 
Step  Action 
1  ATTENTION: RTP and cables are intended for permanent installation within their own enclosure. 
ATTENTION: The RTP combines the two groups of 8 inputs into one group of 16. 
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 desired cable to 16 point DC DI module at controller. Choose from: 
900RTC-L010  Remote Terminal Low Voltage Cable Assembly, 1.0 meters long 
900RTC-L025  Remote Terminal Low Voltage Cable Assembly, 2.5 meters long 
900RTC-L050  Remote Terminal Low Voltage Cable Assembly, 5.0 meters long 
•  Install 16 point DC DI module label into the module connector cover. 
•  Connect shield drain wire 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 RTP to DIN rail. 
•  Latch to rail. See page 244. 
•  Connect cable to RTP.
