Model 2400XC/2400XS Explosion-Proof M/P Converter

Brand: Fairchild Industrial Products
Request Information
The Rotork Fairchild 24XC and 24XS M/P Converters are motor driven pneumatic regulators with motor assemblies enclosed in a NEMA 4X Explosion-proof enclosure.

AC Control Unit (24XC)
The AC Control unit for the 24XC unit is a continuous operation motor available in 115 Vac. A feedback potentiometer option is available for these units.

DC Pulse Input Unit (24XS)
The DC pulse input assembly for the 24 XS unit is a Clock Generator/Translator board available for the 12 Vdc or 24 Vdc pulse input. This allows the use of an external Controller with a 12 Vdc or 24 Vdc output.

DC Analog Input Unit (24XS)
The DC Analog input assembly is an Amplifier (Proportional Control) and Translator board which allows operation with a 4-20 mA or 1-5 Vdc Analog input. Minimum-maximum limit switches are standard on this unit.

Reverse action and split ranging on the Analog unit can be achieved in the field.

TTL Input (+5vD) (24XS)
The TTL input unit is equipped with a Translator board only. The user is required to supply the digital input pulses.

The control assembly for the 24XS unit is a stepper motor with an integral Translator board which converts 12 Vdc or 24 Vdc digital input pulses supplied by the customer into control logic to drive the stepper motor.
