FEATURES 

 

The 

M2 RC2800PRKX1SU 

is our Mid Grade rack-mount controller. The 

RC2800PRKX1SU

 was developed for “Commercial Grade” 

Polarity Pedestal Models.  

 

The 

M2 RC2800PRKX1SU 

uses a Microchip PIC18F2520-I/SP for Micro processing user commands, M2 software and EEprom for 

memory. User modes include: (3) Operational / Run Modes and (10) programmable presets. 

 

The 

M2 RC2800PRKX1SU 

uses 

PWM

 (Pulse Width Modulation) for speed control, allowing for full torque at the slowest input 

speed. Location heading from the motor assembly is supplied via an Open Loop Circuit to the controllers’ microprocessor. 

 

The 

M2 RC2800PRKX1SU 

software also includes a full 

GUI

 software for setup and run modes and a Interface Control Document 

(ICD)  

is supplied with the 

RC2800PRKX1SU.  

 

Computer interface to the 

RC2800PRKX1SU

 is via an RS232 port.
