• I/O type and range

• Zero and span adjustments

• User’s linearization table setting

(max. 101 points, specified within -15 to +115 % for both

input and output)

(Refer to the instruction manual)

‘One-Step Cal’ calibration: With I/O type and the full-scale

range configured via the internal DIP switches, precise 0 %

and 100 % ranges are calibrated via the front control

buttons with a help of LED. Also I/O calibration and fine

adjustment are available with a PC.

Configurator connection: 2.5 dia. miniature jack;

RS-232-C level

PERFORMANCE

Accuracy: Input Accuracy + Output Accuracy

Input accuracy: (% of input range)

(Inversely proportional to the span.)

-1000 – +1000 mV : ±0.01 (%)

-10 – +10 V : ±0.01

0 – 20 mA : ±0.02

Output accuracy: ±0.04 % of output range

(Inversely proportional to the span.)

Temp. coefficient: ±0.015 %/°C (±0.008 %/°F) of max. span

Response time: ≤ 0.5 sec. (0 – 90 %)

Line voltage effect: ±0.1 % over voltage range

Insulation resistance: ≥ 100 MΩ with 500 V DC

Dielectric strength: 1500 V AC @ 1 minute

(input to output or power to ground)

500 V AC @ 1 minute (output to power)

CALCULATION EXAMPLES OF OVERALL ACCURACY

[Example] Input Signal 1 – 5 V, Output Signal 1 – 5 V

Max. Input Range (20 V) ÷ Span (4 V) × 0.01 % +

Max. Output Range (20 V) ÷ Span (4 V) × 0.04 % = 0.25 %
