Connection example 2: When the electricity meter is connected
PCB
Connect the electricity meter to CH1. In this case, the use of CH2 is prohibited.
z Apply voltage terminal TM201 (CN412)
„
When a power supply must be provided at the input device you want to connect, use the Apply
voltage terminal TM201 (CN412).

*2: Make the power supply DC 12 to 24 V. Select a power supply capacity with an ample
surplus for the connected load.
*3: Do not impress a voltage exceeding 24 V across K1-K2.
*4: The allowable current is DC 10 mA or less. (Recommended DC 5 mA) Provide a load
resistance such that the current becomes DC 10 mA or less. Select very low current use
contacts (usable at DC 12 V, DC 1 mA or less). A twisted pair cable 0.33 mm
should be used. Maximum length of cable is 25 m (82 ft).
