MODEL: 18KDYH2

Rack-mounted DCS Signal Conditioners 18K-RACK

[2] OPTIONS (multiple selections)

Opencircuit detection

blank: none

CURRENT LOOP SUPPLY

(applicable to HART signal, opencircuit detection selectable)

Functions & Features

/B: Opencircuit detector (Only for HART signal)

Connector output polarity reversal

blank: none

• Powers a 4 – 20 mA DC current loop

• Isolates and relays HART signals

• Shortcircuit protection

/RE: Connector output polarity reversal (Only for HART signal)

• Opencircuit detection selectable

• Module can be retracted without removing wiring for an

insulation test

GENERAL SPECIFICATIONS

Construction: Rack-mounted; terminal access via screw

terminals on the front and connector on the rear; terminal

cover provided

Typical Applications

Connection

• 2-wire HART transmitters

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

and connector

Output 1: Connector

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

and connector

Power input: Supplied from connector

Screw terminal: Nickel-plated steel

Isolation: Input to output 1 to output 2 to power

Overrange output: Approx. -10 to +110 %

Zero adjustment: -5 to +5 % (front)

Span adjustment: 95 to 105 % (front)

Open-circuit detection: This function enables the input

device to detect open circuit of output circuit isolated from

the input circuit.

MODEL: 18KDYH2–A[1]–R[2]

ORDERING INFORMATION
