GENERAL SPECIFICATIONS
Connection
 
Output: 4-pin e-CON connector
  Unit side connector XN2D-1474-S002 (Omron)
  Recommended cable side connector XN2A-1470 (Omron)
  Applicable wire size 0.08 - 0.5 mm2 (AWG28 - 20)
  Outer sheath diameter: max. 1.5 dia
  (The cable 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: Output 1 or output 2 to exc. supply to internal bus or internal power
Output range: Selectable with the side DIP SW
Module address: With rotary switch
Output at the loss of communication: Selectable with the side DIP SW
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.
Output status indicators: Red LED; Refer to the instruction manual.

OUTPUT
Output range: Selectable between 0 – 20mA DC
Operational range: -5 – +105 % (in percentage of output range) ≤ 0 mA DC
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)
Atmosphere: No corrosive gas or heavy dust
Mounting: DIN rail
Weight: 60 g (2.12 oz)

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)
