Inputs and outputs
- 8 multifunction inputs (MULTI_IN) are programmed as analog or digital; the voltage input range is 0…32.8 V (or 0…16.9 V), the current input 0…25 mA and the frequency input 0…35 kHz.
- The motor outputs offer a duty cycle of 0…100% and a PWM frequency up to 30 kHz; overtemperature shutdown is integrated for each output channel.
- The 2 I/Os on pins C6 and C7 can be used as PWM outputs from 1 Hz to 1 kHz; the outputs include current measurement (INA).
Load tests
At +85 °C, 28 V supply voltage and a resistive load, the datasheet gives these load tests: each of the three BTN outputs as a full bridge carries 6.6 A permanently, and a single full bridge 12 A permanently. With 20 kHz / 96 % PWM (inductive load) a single full bridge is given as 10 A permanent. See the datasheet for the detailed table.
Supply, communication and housing
- The supply voltage range is 8…32 V; 14.5…32 V with VREF = 10 V.
- The CAN interface is 2.0 A/B (ISO 11898-2 and ISO 11898-5) and CAN-FD capable; the LIN interface depends on the assembly options.
- Connector Delphi / Aptiv – 211PC249S0033, weight 290 g. IP6K8 applies with the correct mounting position (connector facing downwards) and, according to the accessories list in the datasheet, when the protection cap and corrugated tube are used.
For a single motor
If you only need one motor output, see the MRS Motor Controller 10 A CAN. For other products: MRS Electronic, Control units.
EHR Elektronik develops application software for MRS Electronic control units. The EHR CANopen node software is also available on request for this product; details are on the CANopen I/O node page.
MRS Motor Controller 3CH 10 A – Data sheet (PDF)Frequently asked questions
Can hydraulic proportional valves be driven?
Yes. The module has 2 current-controlled PWM outputs, for example for controlling two hydraulic proportional valves; the PWM output range is 1 Hz to 1 kHz.
What input types are available?
The 8 multifunction inputs can be used as analog (0…16.9 V or 0…32.8 V), current (0…25 mA), digital, sensor and frequency inputs (0…35 kHz); according to the datasheet these depend on the assembly option.
Is CAN FD supported?
According to the datasheet, the CAN interface is CAN-FD capable; the LIN interface depends on the assembly options.
