  • Page 5 ST950 Plus+ User Manual Important Plus Considerations To provide the most reliable operation, the Siemens ST950 Plus controllers use a DC supply. To maintain all street voltages within ELV limits, equipment outside the cabinet must be supplied with voltages within the band 0 to +48V DC with respect to earth. Voltages beyond that will result in overall voltages within the system being in excess of the ELV limit as defined by BS7671.

    ST950 Plus+ User Manual CIC Card and CTB (Backplane) 3.16.1 Overview The CIC is the Plus communications hub and provides controller power distribution for the remote nodes, via the street wiring. Its main role is to provide safe communications to remote nodes such as RAG, Wait and Nearside nodes in order to control the traffic signalling.
  • Page 57 ST950 Plus+ User Manual Street wiring is terminated directly to the CTB via cage clamp terminal blocks. The CTB in turn routes its connected signals to the CIC via DIN standard connectors. The CIC is fitted with a metallic cover to provide a degree of protection from accidental contact. However, there are no hazardous voltages present on the PCB.
