With the ESX-MBC, we present a new CAN-J1939 module especially for the agricultural and construction machine sector, to control electric motors and actuators in a performance range of up to 200 W. It provides four fast PWM half bridges (each 10 A) with current measurement and two further digital power outputs (each 4 A). Of these, two half bridges respectively, which can be combined to form one motor full bridge, and one digital output are supplied via a safety relay (max. 15 A per safety relay). The module also possesses four multifunction inputs, one module identification output, one digital output and one fixed voltage output for sensor supply. All analog signals are processed with a 12-bit resolution.
The ESX-MBC is supported through the CANopen safety protocol and J1939. In addition, the control unit is equipped with 200 Watt power outputs.
