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).

Input 1, input 2, and reset input specifications

• Impedance during short-circuit: 1 k

max.

(At 0 

, the outflow current is approximately 12 mA.)

• Residual voltage during short-circuit: 2 V max.
• Impedance when released: 100 k

min.

• Max. applied voltage: 40 VDC max.

Lock input specifications

• Impedance during short-circuit: 1 k

max.

(At 0 

, the outflow current is approximately 1.5 mA.)

• Residual voltage during short-circuit: 2 V max.
• Impedance when released: 100 k

min.

• Max. applied voltage: 40 DVC max.
• The contact relay should be one which can open/close 5 V,

1.5 mA.

* There is no 12 V DC with 12 - 24 V DC/24 V AC types.

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.
