Warning
Turn the power supply to the instrument off before wiring or checking.
Working or touching the terminal with the power switched on may result in severe injury
or death due to Electric Shock.

Notice
• The terminal block of the JCD-33A is designed to be wired from the left side.
The lead wire must be inserted from the left side of the terminal, and fastened by the terminal screw.
• Use a thermocouple and compensating lead wire that correspond to the sensor input
specification of this controller.
• Use the 3-wire RTD which corresponds to the input specification of this controller.
• This controller does not have built-in power switch, circuit breaker or fuse. Therefore, it is
necessary to install them in the circuit near the external controller.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)
• For a 24V AC/DC power source, do not confuse polarity when using direct current (DC).
• For the OUT1 (Limit control output terminals 5-6), externally use a relay according to the
capacity of the load to protect the built-in relay contact.
• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources or load wires
to avoid external interference.
• Do not apply a commercial power source to the sensor connected to the input terminal nor
allow the power source to come into contact with the sensor.
Lead wire solderless terminal
Use a solderless terminal with an insulation sleeve in which an M3 screw fits as shown below.
The torque is approximately 0.6N•m to 1.0N•m.
