OUTPUT SPECIFICATIONS

Output frequency: Input frequency × scaling factor (scaling

factor = output span frequency / input span frequency)

Minimum frequency span requirement: 20 % of the selected

output frequency range

Saturation voltage: 0.6 V DC

Maximum frequency: 10kHz

■ Voltage Pulse

H level: Rating (5, 12 or 24 V) ±10 %

L level: ≤ 0.5 V

Load resistance: ≥ 1 kΩ (5V ), ≥ 2.4 kΩ (12 V), ≥ 4.8 kΩ (24

V)

Maximum frequency: 10 kHz

OUTPUT PULSE WIDTH

• No conversion to one-shot: Duty ratio approx. 50 % (Fixed

duty ratio even when the output frequency changes.)

• One-shot Output: Preset pulse width ±20 %

Optional pulse width: 30 μsec. – 300 msec.

INSTALLATION

Power input

•AC: Operational voltage range 85 – 132 V,

47 – 66 Hz, approx. 6 VA

•DC: Operational voltage range: Rating ±10 %, or 85 – 150

V for 110 V rating; ripple 10 %p-p max.; Approx. 3.3 W (140

mA at 24 V)

Operating temperature: -5 to +60°C (23 to 140°F)

Operating humidity: 30 to 90 %RH (non-condensing)

Mounting: Surface or DIN rail

Weight: 400 g (0.88 lb)

PERFORMANCE in percentage of span

Accuracy

Output 10 kHz range: ±0.2 %

Output ≤ 1 kHz range: ±0.1 %

Response time

Input ≥ 10 Hz range: 0.3 sec. + input cycle + output cycle

Input ≤ 1 Hz range: Two (2) input cycles + output cycle

Response time is defined as time required for the first

output pulse to be provided for a step input (0 – 100 %).

Insulation resistance: ≥ 100 MΩ with 500 V DC

Dielectric strength: 2000 V AC @ 1 minute (input or sensor

excitation to output to power to ground)
