Taking measurements without delay

Canway (Germany) has launched the CW-301 CANpwr, a CAN-controlled power relay interface. The device makes it possible to take measurements in vehicles without delay since you don’t need to operate any switches.

THE MODULE SUPPORTS RAPID AND AUTOMATED control of power relays via CAN messages as well as manual switch control. This makes it possible to activate the power supply in mobile measurement applications by means of a specific CAN network signal or charge batteries installed in measurement technology to defined vehicle statuses. The main field of application envisaged for the new module is the development departments of automotive OEMs.
The CW-301 is equipped with three switchable outputs with nominal voltages of 12 VDC or 24 VDC. It is rated for a maximum switching current of 10 A per voltage output. Thermal circuit-breakers safeguard the switch components. The maximum switching capacity is 360 W at 12 VDC and 720 W at 24 VDC.
The response and release times are specified as 10 ms at 20 °C. Providing data transmission rates of up to 1 Mbit/s (according to ISO 11898-2), the module supports the CAN base (11-bit ID) and extended (29-bit ID) frame formats. It is optionally possible to terminate the CAN interface with a 120-Ohm termination resistor. The module is also equipped with three toggle switches to facilitate switching the outputs manually.
The CAN interface supports a range of different settings. Per channel it is possible to set a follow-on time of up to 100 min as well as message IDs and switching conditions based on user data contained in the message. Utilizing filters and masks it is possible to take into consideration any number of data bits as switching conditions.
The module comes in an IP40 rated, anodized aluminum housing, measuring 171 mm x 71 mm x 113 mm. It is designed to operate in temperatures ranging from -20 °C to +70 °C. And requires a power supply of 9 VDC to 30 VDC. In sleep mode the CW-301 draws a current of 9 mA at 12 VDC. A 9-pin D-sub connector is available to connect the CAN network.
