Reference
A terminal connection type (model :IR-CZQH7T) does not have contact output.
Make sure to turn off the power supply for preventing an electric shock when
connecting and wiring.
Provide a low impedance earth ground (lower than 100Ω) connection to the ground
terminal.
The current output is 4 to 20mA DC and isolated.
Connect the signal terminals and a receiving instrument.
The contact output is the open collector output (photo-coupler).
Use a receiving instrument under the ratings (30V, 50mA).
