Digital input sensor decoder. 12/24v AC or DC input

Product code:

8 Input Sensor Decoder This Sensor decoder has 8 optically isolated inputs and a common that are activated when a voltage of 12V-30V AC or DC is applied. It is useful for monitoring switch type sensors where a suitable excitation voltage is available, or the output of perhaps a PLC with 12V or 24V open collector outputs. The 8 inputs are returned as a byte. 0 means inactive, 1 means excitation voltage present on that input (with respect to common/White). The TK-UNI-8 may be programmed to sensor address between 1-8 using the 2WireProgrammer/tester
