The BSTI136 is a universal isolating transmitter featuring an independently adjustable trip-point with relay contact output. The standard BSTI136 will accept DC voltage or current input signals directly (0.1V up to 2kV, 0.1mA up to 2A). Final calibration is trimmed using the front accessible ‘offs’ and ‘span’ 15-turn trim adjustments. The output signal level is indicated by a green LED on the front of the module. Special requirements for input/output response are accommodated with the customised response option. The trip circuit is operated directly from the pre-conditioned input circuit. The trip-point is adjusted by a 15-turn potentiometer from the front of the module. Trip status is indicated by the red LED. Standard relay contact output is a change over contact rated at 8A/250Vac resistive. Various power supply choices are available ranging from 240Vac down to 8Vdc all featuring power isolation.
