Electromen OY DC Motor Controller, 12 → 42 V dc, 100 A, 42 V dc

The EM-282 is a full bridge DC-motor starter. It is designed to work with DC-motor in applications where some special functions are needed.
Starter has adjustable acceleration and deceleration ramps, which make possible the smooth starts and stops,adjustable current limit protects motor against overcurrent and there is also current limitation for brake (regeneration).

This device has also two settable speeds, which are useful in positioning applications.
Control inputs FW and BW start the forward and backward run.
STOP is for the motor shut-down but there are also available individual limit inputs for FW and BW directions.
SPEED-2 input activates pre-set speed-2, but it can also be used as input for analogue speed control signal 0-5V.
FAULT terminal has at the same time input and output function, the pin is normally high, but is pulled down in overheat and conditionally also in current trip situation
There are 2 selectable control modes, continuous and impulse. In continuous mode the motor runs as long as the control is active. In impulse mode a short command starts the motor, and only a new impulse will change the status.
The card has selectable input logics for both control and limit inputs
For parameters setting there is 3 options: EM-236 interface unit, EM-268 with Menthol-Lite PC-program and EM-326 with Menthol-App application for smartphone
