PERFORMANCE

Conversion accuracy (in percentage of output range)
±0.08 % (@ output range 0 - 20 mA)
Conversion accuracy is inversely proportional to output span.
Conversion accuracy computation example:
When output range is 4 - 20 mA: conversion accuracy = output span standard value (20 mA) ÷ output span (16 mA) × 0.08(%) = 0.1 (%).
output span standard value is the same as the span at output range 0 - 20 mA DC.
Conversion rate: 4 msec.
Output circuit time constant: ≤ 1 msec. (0 → 90 %)
Data range: 0 – 10000 of the output range
Data allocation: 2
Module addresses in use: 2
Temp. coefficient: ±0.015 %/°C (±0.008 %/°F)
Insulation resistance: ≥ 100 MΩ with 500 V DC
Dielectric strength:
1500 V AC @ 1 minute (output to exc. supply to internal bus or internal power to ground)
