Load resistance: ≤ 500Ω

INSTALLATION

Max. current consumption: 70 mA
Exc. supply: 24 V DC ±10%
Exc. supply current consumption: 50 mA
(Power supply for output circuit is generated from exc. supply)
Operating temperature: -10 to +55°C (14 to 131°F)
Operating humidity: 30 to 90 %RH (non-condensing)

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: 2 msec.
Output circuit time constant: ≤ 1 msec. (0 → 90 %)
Data range: 0 – 10000 of the output range
Data allocation: 2
Module addresses in use: 1
Power output (between 1 to 4 pin of output connector): Rated current 0.5 A DC per channel (rated current 3 A for internal fuse (slow blow fuse i2t (A2sec.) max. 5.04); Total: 1 A DC
Temp. coefficient: ±0.015 %/°C (±0.008 %/°F)
Insulation resistance: ≥ 100 MΩ with 250 V DC
Dielectric strength:
  1500 V AC @ 1 minute (output 1 or output 2 or exc. supply to internal bus or internal power to ground)
  300 V AC @ 1 minute (output 1 or output 2 to exc.supply)
