4.3 DI/Alarm Output Wiring (Option)

WARNING
‡ @ Be sure to wire after turning off the POWER.
‡ A When the power source has been connected to the Alarm output, turn off that power source.
‡ B When a hazardous voltage supplies to alarm terminal:
‚ • • j • @ Never touch terminals preventing from electric shock.
‚ ‚ • j • @ Attach covers to terminals.
‚ ƒ • j • @ Wires should be double shielded.
‚ „ • j • @ Adopts round pressure terminal connectors with insulation cover for wire, preventing from lose
connection.
CAUTION
Precautions for Wiring the DI
‡ @ DI input has the built-in drive power source. Do not apply a voltage to a DI input terminal from the
outside.
‡ A A DI input contact capacity should be a withstand voltage of 50V DC, 16mA or more, ON
resistance of 20ƒ ¶
‡ B Do not use unused terminals as relay terminals.
Precautions for Wiring the Alarm Output
‡ @ • @ An alarm output contact capacity is as follows• F
250VAC • F
30VDC • F
125VDC • F
‡ A • @ Attach an anti-surge protective circuit (surge absorbers, etc.) to an output terminal, as required.
‡ B • @ Attach a round press-fitting terminal with insulated sleeve (for M3.5) to the end of an electric wire.
‡ C • @ Keep alarm output wiring away from input wiring.
‡ D • @ Do not use unused terminals as relay terminals.
