INSTALLATION

Power input

• AC: Operational voltage range: rating ±10 %,

50/60 ±2 Hz, approx. 2 VA

• DC: Operational voltage range: rating ±10 %,

or 85 – 150 V for 110 V rating, ripple 10 %p-p max.,

approx. 2 W (18 mA at 110 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: ±0.5 %

Temp. coefficient: ±0.05 %/°C (±0.03 %/°F)

Response time: ≤ 1 sec. (0 – 90 %)

Ripple: 0.5 %p-p max. (50/60 Hz)

The output ripple may increase when there is great

difference between the frequencies of input signal and

power supply.

Line voltage effect: ±0.1 % over voltage range

Insulation resistance: ≥ 100 MΩ with 500 V DC

Dielectric strength: 2000 V AC @ 1 minute

(voltage input to current input to output to power to ground)
