Connected to internal bus connector

•Internal power: Supplied from internal bus connector

Isolation: Output 1 to output 2 to exc. supply to internal bus

or internal power

Output range: Selectable with the side DIP SW

Module address: With DIP 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: 80 mA

Exc. supply current consumption: 60 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: 110 g (0.24 lb)

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.
