The BAPC253 is a analogue to pulse conversion module specifically designed to interface to PLC or other systems requiring pulse inputs. The BAPC253 can be configured for a wide range of process and probe inputs (for full range see ordering information). Output modes available are NPN, PNP, or DC Pulse. The output frequency range can be factory calibrated for any frequency span from 10Hz up to 10kHz, with low scale frequency offsetting also available. eg. Input 0 – 10Vdc Output 1 – 2kHz. The input/output configuration can also be set for reverse action if required using internal coding pins. Final calibration is trimmed using the front accessible zero and span 15-turn trim adjustments. A front mounted L.E.D. and a test socket verify module function and assist in calibration checks. The output pulse amplitude is adjustable via an internal 15-turn reference potentiometer which allows exact pulse voltage levels to be set. The BAPC253 provides isolation up to 2kV rms between supply/output and input terminals. Double surge protection is standard with all Series 200 transmitters to prevent failure due to spikes induced by DC switched inductive loads.
