Description
The AC Voltage Transducer BAVT245 is a loop powered, isolating transmitters that accepts voltage up to 500Vac. The BAVT245 is ideal for field enclosures or as a space saver in larger control cabinets. Standard output is 4 – 20mA with a minimum supply voltage of 8V. This enables the BAVT245 to be used in 12V battery supply systems or in automotive applications. Other factory set output configurations are 10 – 50mA loop powered and 0 – 10mA, 0 – 20mA or voltage output in 3-wire connection. Reference for 3-wire connection is the negative supply. Higher voltages are permissible with the use of suitable series resistors. Double surge protection is standard with all Series 200 loop powered transmitters to prevent failure due to spikes induced by DC switched inductive loads. The input circuit features an averaging precision rectifier to accurately measure sinusoidal waveforms having frequencies in the range 10 to 1000Hz. The input output isolation is greater than 2kV rms Zero suppression (OFFS) is adjusted internally via an optional 15-turn potentiometer. Final non-interacting ZERO and SPAN adjustments are accessible from the front of the module. A front mounted L.E.D. and a test socket verify module function and assist in calibration checks without disconnection of output wires.
