Follow instructions in 'Cautions during Use'. Otherwise, it may cause unexpected accidents.
•
Install a surge absorber at each end of inductive load coil when controlling high-capacity power relay or inductive load (e.g.
magnet).
•
24VDC power supply should be insulated and limited voltage/current or Class 2, SELV power supply device.
•
Check the polarity of the terminals before wiring the temperature sensor.
For RTD temperature sensor, wire it as 3-wire type, using cables in same thickness and length.
For thermocouple (CT) temperature sensor, use the designated compensation wire for extending wire.
•
Keep away from high voltage lines or power lines to prevent inductive noise.
In case installing power line and input signal line closely, use line filter or varistor at power line and shielded wire at input
signal line.
Do not use near the equipment which generates strong magnetic force or high frequency noise.
