Universally useable PLC with max. 24 binary inputs, 24 binary outputs, 16 analog inputs, 4 analog outputs, 2 CAN (Controller Area Network) and RS232 interfaces. CAN allows free interconnection of many NLC systems to integrated control system with data acquisition and supervisory control on PC. Programs are written in GRAFCET like language HORSET. Programming system effectively supports data exchange between all CAN nodes without programming at application software level.

Robust CAN linked  passive input/output modules based on PCA82C150 chip from Philips. They are used for increasing of NLC-3 IO number or as inputs and outputs of VTT-2, VTT-3 terminals end NDS intelligent panel meter. They also can be used by controllers from other producers, which are able to communicate by Philips SLIO controllers.
IO circuits, internal logic circuits and CAN circuits are one another galvanically decoupled.
