Isolation: Input 1 to input 2 to input 3 to input 4 to input 5 to input 6 to input 7 to input 8 to exc. supply to internal bus or internal power
Input range: Selectable with the side DIP SW
Module address: With DIP switch
Terminating resistor: Built-in (DIP Switch, default: disable)
Configuration mode: With DIP switches on the side panel
Status indicator: Bi-color (red/green) LED; Refer to the instruction manual.
Input status indicators: Red LED; Refer to the instruction manual.
INPUT
Input range: -20 – +20 mA DC configurable
Input range: :-5 - +105 % (in percentage of input range)
Input resistance: 100 Ω
INSTALLATION
Max. current consumption: 200 mA
Operating temperature: -10 to +55°C (14 to 131°F)
Operating humidity: 30 to 90 %RH (non-condensing)
Atmosphere: No corrosive gas or heavy dust
Mounting: DIN rail
Weight: 100 g (3.53 oz)
PERFORMANCE
Conversion accuracy (in percentage of input range)
±0.1 % (@ input range -20 - +20 mA)
Conversion accuracy is inversely proportional to input span.
Conversion accuracy computation example:
When input range is 4 - 20 mA: conversion accuracy = nominal input span (40 mA) ÷ input span (16 mA) × 0.1(%) = 0.25 (%).
Nominal input span is the same as the span at input range
-20 - +20 mA DC.
Conversion rate: 8 msec.
Input circuit time constant: Approx. 1 msec.
Data range: 0 – 10000 of the input range
Data allocation: 2
Module addresses in use: 4
Temp. coefficient: ±0.015 %/°C (±0.008 %/°F)
Insulation resistance: ≥ 100 MΩ with 500 V DC
Dielectric strength:
500 V AC @ 1 minute (input 1 to input 2 to input 3 to
input 4 to input 5 to input 6 to input 7 to input 8)
1500 V AC @ 1 minute (input to exc. supply to internal bus
or internal power to FG)
