16 Point Analog Input
Step Action
1 ATTENTION: RTP and cables are intended for permanent installation within their own enclosure.
ATTENTION: The RTP labeled “DI, DO, AO RTP ASSY” with jumpers J2-J9 is the correct one for 16
point AI.
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 16 point Analog Input module at controller.
Choose from:
900RTC-3210 Remote Terminal Cable assembly, 1.0 meters long
900RTC-3225 Remote Terminal Cable assembly, 2.5 meters long
• Install 16 point Analog Input 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).
