The Siemens ST950 Plus
+
system is part of the wider ST950 family of controllers and associated
equipment. The ST950 Plus
+
system will run very similar firmware and offers same facilities as the
rest of the ST950 family, including license enabled integral MOVA8 and integral UTMC OTU
facilities.
The ST950 Plus
+
Controller is supplied as a single-door outer case with a 6U logic rack and
equipment mounting frame.

The Plus
+
Traffic Controller provides ELV Power and communications, using a four-core armoured
cable, to a number of intelligent Plus
+
Nodes on the street. The cable connects at the cabinet to a
‘Cabinet Interface Card’ (CIC) via its ‘Cable Termination Backplane’ (CTB).
Each CIC supports a number of on-street cables (arms or rings) each with individual electronically
controlled power switch off capabilities.
