The decentralized measurement data acquisition module µCAN.4.ao-Snap by Microcontrol (Germany) was designed for output of up to four analog signals.
The module features four analog outputs which optionally provide a voltage signal (±10 V) or a current signal (0 mA to 20 mA). The digital process value is scaled to an analog output signal in a DIN-rail casing which is 22,5 mm in width. The CAN interface supports CANopen and J1939 protocols. The analog signals are transmitted via screw plugs. The module can be configured completely and the analog variables are output via the CAN interface. The current device state is indicated via a bi-color LED. The analog output module is designed for working in an extended ambient temperature range of -40 °C to +85 °C.
Up to four analog signals may be output, the signal type (voltage / current) is parameterized via a CAN network. The analog output values are transmitted to the µCAN.4.ao-SNAP via CAN. The bit rate of the CAN interface may be adjusted within a range of 50 kBit/s to 1 MBit/s. A terminating resistor may be activated via a switch in the device. The CANopen protocol of the module complies with the CANopen standards CiA 301, CiA 305, and CiA 404. Both, the 11-bit identifier and 29-bit identifier may be used on the process data objects (PDO). The product is protected by an IP66-rated aluminum casing.
