M100C Series of Motor Actuators with
R81C Interface Board
The M100C Series Motor Actuator is used in damper and valve
applications where proportional control from a digital controller is
required.
The M100C has the capability of communicating with Metasys ®
AHU/UNT or DSC1000 controllers depending on the position of the 8-pin
DIP switch. Other functions that are user programmable include master or
slave configuration, direct or reverse acting mode, the address to which the
actuator will respond and the linear or S-curve response characteristic.
