EM-106A controller is designed for brushless hall-feedback DC-motors. The device uses mosfet-type power stage with high efficiency. EM-106A can be connected to 60- or 120 degrees commuting motor. Standard driving includes speed adjustment, stopping, direction change and braking. The controller can be installed using screws or a standard rail mounting base.

There are two control modes: Within direct driving mode the motor voltage is set in proportion to the control voltage as with a normal DC-motor. Alternatively in frequency locked mode the controller uses the halltransducer signal to speed adjustment besides commuting. This mode gives very precise speed referenced to the control voltage. As an additional feature the controller has an adjustment for loop response so that it provides as stable control as possible within all applications. Control input can be scaled with a trim. The current limit is set with a trim, it restricts driving when motor current exceeds the given value. The controller is protected against reversed input voltage polarity and fuse protected against over current.

EM-115-48 motor control unit is designed for big permanent magnet DC-motors. The power control is done with PWM method (Pulse Width Modulation). This facilitates high efficiency and small temperature losses. Thanks to a high switching frequency the unit operates quietly. A battery or a filtered DC-supply will do as a power source.

The maximum output given by the unit depends on the installation. When operating at maximum power output sufficient air ventilation has to be taken care of. The unit operates in 4-quadrants so it drives and brakes in both directions. The braking is done with regenerative way feeding braking energy back to power supply. When a battery is not used as a power source the braking energy will be fed to the internal resistance of the motor. The motor rpm can be set either with potentiometer, trim or external voltage signal. The output acceleration ramp and current limit are set with trims, the current limit is indicated with a red LED. A load affecting the motor rpm can be eliminated with a compensation trim. The power stage is protected against voltage peaks, overload and temporary shortcuts. Even the incorrect polarity does not damage the unit as long as a fuse of recommended value is used.

8-channel alarm panel

FEATURES:

* 8-channels;

* Selectable input mode n.o. or n.c. alarm contacts;

* Settable input delay;

* Settable alarm output delay;

* Relay output for alarm;

* Blinker and memory for alarm;

* Realtime indication;

* Standard panel mounting size;

* Protected against inverse polarity;

EM-M50 is an 8-channel alarm logic suitable for alarm control in various automation processes. EM-M50 can be installed to standard 96*96 millimeter slot. Each of the 8-channels can be set to activate either with opening or closing contact. Inputs can be controlled with voltage signal also. The indication output display the state of the input in realtime so the unit is s.c. transparent. Indication outputs can be inverted as well, then the output is reversed compared to input.

The alarm logic operates in following manner. When the fault signal is detected, the indication light of the particular channel starts to blink and group alarm relay and alarm output gives an alarm. If the fault causing the alarm is removed the alarm stays. The alarm can be removed only with reset button. When the alarm is acknowledged the group alarm is removed, indication light stays lit until the input situation has been normalized. So new alarm blinks and old one stays lit. The alarm input can be delayed for 0.5 to 4 seconds.

Alarm output can be delayd for 0 to 10 seconds. Delay is the same for all channels. Operation of the unit can be verified with test button. EM-M50 is equipped also with test and reset inputs. With these inputs several units can be connected in parallel to form groups. The group alarm relay is de-energized when alarm occurs so an operating voltage failure causes an alarm as well. Operating voltage input is protected against voltage surges and inversed voltage.;

Descripcion:;

EM-241A 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 it can also be used as an end-stop. This device has also two settable speeds, which are usefull 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 preset speed-2, but it can also be used as input for analog 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. If FAULT-line is pulled down externally it will cause a stop and prevent the new start. For example, it is possible to link fault pins of several units together and achieve a syncronous stop. There are two selectable control modes, continuous and impulse. In continuous mode the motor runs as long as the control is active. In impulse mode a short comand starts the motor, and only a new impulse will change the status. There is also few special settings start-kick and auto reverse. The card has selectable input logics. Inputs are divided in two groups, control and limit -inputs. Groups can be individually set for NPN or PNP logic. The parameters are set with EM-236 interface unit. Operation of the controller and some of its functional values can also be monitored with EM-236 interface unit.
