Description
The BDTI135 is a isolating transmitter featuring two independently adjustable trip points with relay contact output. The standard unit will accept DC voltage or current input signals (0.1V up to 2kV, 0.1mA up to 2A). Low level sensor or AC input signals require an optional input conditioning card which is factory fitted. 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 by the customised response option. The trip circuits are operated directly from the pre-conditioned input circuit. Both trip points are adjusted by 15-turn potentiometers from the front of the module. Trip status is indicated by red LED. The standard configuration both contacts are referenced to one point (Terminal 5 common). Two independent contact outputs are available on request. Various power supply choices are available ranging from 240Vac down to 8Vdc, all provide power isolation
