8 Digital Switch Input Transmitter (DSIT8)

The switches can be chosen for a common 0 V i.e. they are active high, or a common +V where they are active when switched to 0 V. This is factory configured and needs to be chosen when ordering. 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 inputs states and the power is good to the unit.
