Page 11: Ncp Network Wiring
NCP Network Wiring Controllers may be networked to either a 'main LAN' by an MN50-MI-NCP or to a 'sub-LAN' using a MicroNet Touch Screen. The recommended cable for NCP networks is Belden 9502 dual twisted-pair screened cable with full opto-isolation in areas of high electrical noise. Connect the network to the controller, as shown in the following diagram. - Page 12 I/O Wiring I/O connections include 10 configurable universal inputs (UIs), 2 digital inputs (DI), 6 digital outputs (Line relay), and 4 analogue outputs (AO). The DOs are line relays for switching up to 230Vac, 5A loads. Four analogue outputs provide 0 to 10V. WARNINGS –...

Page 13: Digital Uis
Digital UIs Note: Only dry (voltage free) contacts can be monitored. Maximum count frequency is once every two seconds. 1.Connect one wire from field contact to desired input terminal (8, 9, 10, 11, 12, 13, 14, 15, 16 or 17). Polarity is not important. 2.Connect other wire to one UI common (COM) terminal (31, 32, 33, 34, 35, 36, 37, 38, 39 or 40). -
