IFM Electronic has two splitters to simplify wiring in process valves. The T0 is a passive splitter for NAMUR-type applications while the T5 integrated ASI sensor/splitter incorporates proximity sensors to monitor the state of the valve.
Both IP67-rated splitters are directly mounted on to valve actuators and require only a single field connection. Plug-in connections for the T0 and power through the ASI cable for the T5 help reduce valve wiring.
