[1] OPTIONS

Power Switch

blank: None

CURRENT LOOP SUPPLY

(10 – 50 mA / 4 –20 mA loop)

/S: With power switch

Functions & Features

• 2-wire transmitter circuit with short-circuit protection

• Reposition the shorting pin to switch input signals

between 10 - 50 mA DC and 4 - 20mA DC

• Applicable to smart transmitters

• Can also be used as a 10 - 50 mA DC / 4 - 20 mA DC

isolator

GENERAL SPECIFICATIONS

Construction: Rack-mounted; terminal access via screw

terminals on the front and connector on the rear; terminal

cover provided

Connection

Input: M3.5 screw terminals (torque 0.8 N·m)

and connector

• Module can be retracted without removing wiring for an

insulation test

Output 1: Connector

• Optional power switch

Output 2: M3.5 screw terminals (torque 0.8 N·m)

and connector

Power input: Supplied from connector

Screw terminal: Nickel-plated steel
