MODEL: 18KYCH

Rack-mounted DCS Signal Conditioners 18K-RACK

GENERAL SPECIFICATIONS

Construction: Rack-mounted; terminal access via screw

terminals on the front and connector on the rear; terminal

cover provided

CONTROL OUTPUT ISOLATOR

(applicable to HART signal, opencircuit detection selectable)

Functions & Features

Connection

Input: Connector

• Takes 4 - 20 mA DC as input

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

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

connector

• Isolates and relays HART signals

• Opencircuit detection selectable

• Module can be retracted without removing wiring for an

insulation test

Power: Supplied from connector

Screw terminal: Nickel-plated steel

Isolation: Input to output to power

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

Span adjustment: 95 to 105 % (front)

With power switch: Selectable from the front

(factory default: ON)

• Capable of monitoring input signals at front terminals

• Optional power switch

Opencircuit detection: Input current 0 mA when the output

loop is open.

Photo MOSFET Relay ON Resistance; 3 Ω max.

INPUT SPECIFICATIONS

■ DC Current: Input resistor incorporated

Input current: ≥ 0 mA
