EM-348-SPF DC-MOTOR CONTROLLER with MODBUS 12-24V 15A

56,00 € /unit

EM-348 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. Driver has two selectable pwm frequency 2 or 16kHz. Power stage has smoothed switching technique which is achieved very low RF emissions, so external filter will not needed. Driver has also external brake output which can be used for control magnetic brake or braking resistor in regenerative braking.
This card has integrated Rs-485 bus, with this bus can be control and monitoring driver and also the parameter of driver can be set with bus. This interface has as a standard Modbus RTU protocol. This bus makes possible to connected several cards under one control unit. Card has also two multifuntion control inputs, which can be set for digital or analog mode, depends on used firmware. This card has available with several firmware version for different applications. There is two program version for basic drive and positioning control. Card can be used with pulse or analog feedback from motor. The card has selectable input logics. Inputs are divided in two groups, control and limit /pulse -inputs. These groups can be individually set for NPN or PNP logic.
The parameter setting and monitoring can be done with Modbus or EM-236 interface unit, EM-328 with EmenTool-Lite PC-program. The Program updates domen with EmenTool
