Input connections
• Signal input type
* There is no 12 V DC with 12 - 24 V DC/24 V AC types.
* If a dual-line sensor is connected to a 12 - 24 VDC/24 VAC type,
1) Open collector
3) Contact input
5) For a dual-line sensor
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.
Input 1, input 2, and reset input specifications
• Impedance during short-circuit: 1 kΩ max.
• Residual voltage during short-circuit: 2 V max.
• Impedance when released: 100 kΩ min.
• Max. applied voltage: 40 VDC max.
Dual-line sensor specifications
• Leakage current: 1.5 mA max.

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:
2) For voltage output
4) For a rotary encoder
1. Set decimal position to the last 3rd place.
2. Set the prescale value to 0.002 (1/500).
(Photoelectric sensor,
proximity sensor, etc.)
