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
POTENTIOMETER CONVERTER
Functions & Features
Connection
• Constant voltage method has no effect on the total
resistance value
Input: M3.5 screw terminals (torque 0.8 N·m)
and connector
• Minimal interaction between zero and span adjustments
• Module can be retracted without removing wiring for an
insulation test
Output 1: Connector
Output 2: M3.5 screw terminals (torque 0.8 N·m)
and connector
• Optional power switch
Power input: Supplied from connector
Screw terminal: Nickel-plated steel
