Dual-line sensor specifications
• Leakage current: 1.5 mA max.
• Breaker capacitance: 5 mA min.
• Residual voltage: 2.0 V max.
• Usable voltage: Runs on 10 VDC
* If a dual-line sensor is connected to a 12 - 24 VDC/24 VAC type,
24 VDC (21.6 to 26.4 VDC) and 24 VAC (21.6 to 26.4 VAC)
should be applied to the power supply voltage of the counter.

• Impedance during short-circuit: 1 kΩ max.
(At 0 Ω, the outflow current is approximately 1.5 mA.)
• Residual voltage during short-circuit: 2 V max.
• Impedance when released: 100 kΩ min.
• Max. applied voltage: 40 DVC max.
• The contact relay should be one which can open/close 5 V,
1.5 mA.
What is the prescale function?
The prescale function converts the count into an actual
value (amount) and displays it.
Example
For a device that outputs 500 pulses when 1 m has been fed:
1. Set decimal position to the last 3rd place.
2. Set the prescale value to 0.002 (1/500).
