the users manual for the PC configurator for applicable
cable types.

Conversion accuracy (in percentage of output range)±0.1 % (@ output range -10 - +10 V)
Conversion accuracy is inversely proportional to output
span.
Conversion accuracy computation example:
When output range is 1 - 5 V: conversion accuracy =output span standard value (20 V) ÷ output span (4 V) ×0.1(%) = 0.5 (%).
output span standard value is the same as the span at
output range -10 - +10 V DC.
Conversion rate: 4 msec.
Output circuit time constant: ≤ 5 msec. (0 → 90 %)Data range: 0 – 10000 of the output range
Data allocation: 2
Module addresses in use: 2Temp. coefficient: ±0.015 %/°C (±0.008 %/°F)
Insulation resistance: ≥ 100 MΩ with 500 V DC
