The BSWT240 is designed for SLIDEWIRE or potentiometer inputs ranging from 100Ω up to 20kΩ with zero suppression up to 50% of range. Standard output is 4 – 20mA with a minimum supply voltage of 7V and a maximum up to 40V. This enables the BSWT240 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 0V. Double surge protection is standard with all Series 200 loop powered transmitters to prevent failure due to spikes induced by DC switched inductive loads.
Example: SLIDEWIRE 1kΩ.
calibration 500-1000Ω = 4-20mA output.
Final calibration is trimmed using the front accessible zero and span 15-turn trimadjustments. A front mounted L.E.D. and a test socket verify module function and assist in calibration checks without disconnection of output wires.
