      Description

      The Digital Switch Input Transducer has been designed to provide an isolated output depending upon the digital inputs to the device and the operating mode selected. Originally designed as a transformer tap position transducer, any digital switch inputs can be used. The DSIT can have up to 40 discrete digital inputs typically from the position switches. The current output is determined by the ratio of the active input number divided by the total number of inputs as a proportion of selected current output span. The output can be any of our standard outputs, 4-20 mA, 0-20 mA, 0-10 V, etc. LEDs visible on the front of the unit indicate the state of each input and that power is good to the unit.
