Description
BDI94U meter/transmitter is equipped with one universal input, type: 0/4-20mA, 0-10V, 0-150 mV, Pt 100/500/1000 or TC (K, S, J,T, N, R, B, E). During the measurement process only one kind of inputi s available.Temperature of cold ends is compensated automatically. RTD and TC inputs are fully linearised. The device with current or voltage input operates in the following modes: linear, root, square and user de_ned (max. 20 points). Result is shown on 4-digit LED display. The device is equipped with RS-485/Modbus RTU communication interface and sensor supply output. 2 or 4 relay (or OC) outputs make it possible to adjust the level of the measured signal. These outputs can be controlled according to one or two threshold values. OptionallyBDI94Uwith two relays outputs can be equipped witha ative currento utput. Thed evice can be usedfor controlling and regulation of processes need proportional and thresholdc ontroll ike: temperature processes (heating or cooling), valves controlling or other.
