  Outer sheath diameter: max. 1.5 dia
  (The cable side connector is not included in the package.
   Refer to the specifications of the product.)
 Excitation supply, internal bus:
  Connected to internal bus connector
 Internal power: Supplied from internal bus connector
Isolation: Input to exc. supply to internal bus or internal power
Input range: Selectable with the side DIP SW
Module address: With rotary 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: 50 Ω

INSTALLATION
Max. current consumption: 80 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: 60 g (2.12 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: 4 msec. @ 4 input
Input circuit time constant: Approx. 1 msec.
Data range: 0 – 10000 of the input range
Data allocation: 2
Module addresses in use: 2
Power output (input terminal): Rated curent DC 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: 300 V AC @ 1 minute
(input to exc. supply)
1500 V AC @ 1 minute
(input or exc. supply to internal bus or internal power to ground)
