z Apply voltage terminal ([CNA02])
„
When a power supply must be provided at the input device you want to connect, use the Apply
voltage terminal ([CNA02])
Load

Connected unit
*1: Make the power supply DC12 to 24V. Select a power supply capacity with an ample surplus for the
connected load.
Do not impress a voltage exceeding 24V across pins 1-3.
*c: The allowable current is DC 5mA to 10mA. (Recommended: DC5mA)
Provide a load resistance such that the current becomes DC10mA or less.
Select very low current use contacts (usable at DC12V, DC1mA or less).
*d: The polarity is [+] for pin 1 and [-] for pin 3. Connect correctly.
When connected to Apply voltage terminals of multiple RB units with a connected unit, be sure
to make a branch outside the RB unit using a pull box, etc. as shown on below example.
