Digital input sensor decoder. 12/24v AC or DC input
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
The TK-UNI-8 may be programmed to sensor address between 1-8 using the 2WireProgrammer/tester
