specifications
<Recommended Cables>
Use CVVS 1. 25 sq 2-core single or stranded wire.
<Specifications of Terminal Plate>
Rated voltage: 250 VAC
Rated current: 20 A
<Supply Voltage>
The supply voltage is normally 24 VDC.
However, the voltage at the terminal plate of the detector becomes lower than the source voltage,
depending on the connected safety maintaining device (barrier), type and length of the cable used.
It may also vary with the signal current value (4 to 20 mA).
When wiring the detector, check the following to make sure that the voltage at the terminal plate is
appropriate.
The detector provides stable operation within the power voltage range of 15 to 27 VDC.
< Withstand voltage performance>
The detector has a withstand voltage performance of 500V AC for 1 minute between the power supply
and output signal terminals and the earth (between containers).
CAUTION
Be careful not to damage the internal electronic circuit when wiring.
The connected cables must not be installed together with the motor power cables, etc.
When stranded wires are used, prevent wires from contacting each other.
