425DRM

 

The E-Plex 425DRM has been designed to simplify wiring in electronic systems by providing the reversing
function local to the motor devices thus eliminating long cable runs back to common control systems. This
is accomplished with four DPST relays with the common connections of two relays wired to either side of a
motor. When one relay is active, power is supplied in one direction. When the motor is reversed the relays
switch states allowing the power to flow in the opposite direction. A solid state switch monitors the current
draw of the motors which allows for intelligent feedback as to the condition of the motor.
A typical operation would show an initial surge of current as the motor begins to move which decays to a
steady state level as the motor gets underway. When it reaches its limit the motor will again begin to draw
additional current which can be detected and the power halted stopping the motor from further movement.
For additional safety, in the unlikely event of a thermal runaway condition, a thermal disconnect is used to
remove power from the solid state outputs. Local electronic override capabilities allow independent operation
of the device loads.

 

NOTE: THIS MODULE IS REPLACED BY AN 826QRM WITH CUSTOM FIRMWARE.

The 826QRM replacement  will not constitute any logic changes and will include a plug-and-play cable harness adapter.
