The 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 4-20mA 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
