INSTALLATION
Power consumption
•DC: Approx. 3 W
Programmable features include:
• I/O type and range
• Zero and span adjustments
Operating temperature: -25 to +65°C (-13 to +149°F)
Max. 55°C (131°F) for UL approval
Operating humidity: 0 to 95 %RH (non-condensing)
Mounting: DIN rail
• Burnout action
• User’s T/C table setting
(max. 300 points, input emf specified within

(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

CALCULATION EXAMPLES OF OVERALL ACCURACY
[Example 1]
Maximum range: 0 – 20 mA DC
Minimum span: 1 mA
Input: K thermocouple, 0 – 1000°C, Output: 4 – 20 mA DC
1) Absolute value accuracy (Table 1): 0.25°C
2) CJC error (0.5°C) added: 0.75°C
Conformance range: 0 – 24 mA DC
(Negative overrange current below 0 mA is not available.)
Offset: Lower range can be any specific value within the
output range provided that the minimum span is
maintained.
3) 0.75°C ÷ 1000°C × 100 = 0.075 %
4) 0.075 % < 0.1 % of span. ➠ 0.1 % is selected.
5) Output span 16 mA (= 20 mA – 4 mA)
Max. span 20 mA
Load resistance: Output drive 12 V maximum
■ DC Voltage
Output span ≥ 1/10 of max. span ➠ No need of adding
0.2 %.
Narrow Spans
Maximum range: -2.5 – +2.5 V DC
Minimum span: 250 mV
6) Overall accuracy equals ±0.1 % of span
[Example 2]
Conformance range: -3 – +3 V DC
Wide Spans
Input: K thermocouple, 50 – 150°C, Output: 2.0 – 2.5 V DC
1) Absolute value accuracy (Table 1): 0.25°C
2) CJC error (0.5°C) added: 0.75°C
Maximum range: -10 – +10 V DC
Minimum span: 1 V
3) 0.75°C ÷ (150 – 50)°C × 100 = 0.75 %
4) 0.75 %> 0.1 % of span. ➠ 0.75 % is selected.
5) Output span 0.5 V (= 2.5 V – 2.0 V)
Max. span 5 V
Conformance range: -11.5 – +11.5 V DC
Offset: Lower range can be any specific value within the
output range provided that the minimum span is
maintained.
Output span ≤ 1/10 of max. span ➠ Add 0.2 %.
6) Overall accuracy equals ±0.95 % of span (0.75 + 0.2)
Load resistance: Output drive 1 mA maximum
