GENERAL SPECIFICATIONS Connection •Input: 4-pin e-CON connector PWB connector XN2D-1474-S002 (Omron) Recommended cable connector XN2A-1470 (Omron) Applicable wire size 0.08 mm2 (AWG28) - 0.5 mm2 (AWG20) 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: Input 1 to input 2 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: 100 Ω
INSTALLATION Max. current consumption: 100 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: 2 msec. Input circuit time constant: Approx. 1 msec. Data range: 0 – 10000 of the input range Data allocation: 2 Module addresses in use: 1 Max. consumption current: 100 mA Temp. coefficient: ±0.015 %/°C (±0.008 %/°F) Insulation resistance: ≥ 100 MΩ with 500 V DC Dielectric strength: 1000 V AC @ 1 minute (input 1 to input 2 to exc. supply to internal bus or internal power to FG) 1000 V AC @ 1 minute (for modules combined with this device)
