A CAN bus I/O node has been integrated into Wachendorff’s WDGA CANopen absolute encoder range, giving users the opportunity to combine precision rotary position and/or speed feedback and a means of connecting digital and analogue sensors or other devices on automated motion-centric machinery.
Available in the UK from Variohm EuroSensor, the WDGA-I/O encoders utilise a coded magnetic signal for 4096 counts per revolution as well as each full revolution – providing 16-bit multi-turn absolute position feedback without relying on wear-prone gears or limited life batteries.
These integrate up to three multi-functional inputs and outputs; each may be configured as digital and/or analogue I/O (1x four-wire, 2x two-wire). Users may connect, for example, CANopen compatible thermocouples, PT100 temperature sensors, DMS, 0…4-20 mA or ±10 VDC devices. In addition, the I/O ports can be configured and scaled quickly and easily for a specific type of sensor.
These are suitable for harsh industrial applications as well as mobile machinery, and have an operational temperature range of -40 to +80°C.
