Communication Interface Unit (CIU) 133-550
A micro-controller based control room instrument for collection and display of tank parameter data measured by up to 64 field transmitters - Automatic Tank Level Gauge (ATLG) + Smart Tank Data Transmitter (STDT), Servo Gauge (SG), Hybrid Servo Gauge (HSG), LPG Servo Gauge (LPGSG). There are 4 field input ports, on each port 16 field devices can be connected in multi dropping mode. The CIU Displays tank no., Level & Temperature thus providing redundant display in control room in the event of TFMS PC failure. It provides data output on RS232C port for Host Communication on MODBUS RTU. Open collector, relay and 4-20 mA current outputs can be provided optionally.
