µCAN.1.ai-BOX

The µCAN.1.ai-BOX is a decentralized universal data acquisition module for analogue standard signals (current / voltage). Signals are evaluated and linearized in a rugged aluminium die-cast casing. The CAN interface supports the CANopen protocol.

Features

Sensor signals are evaluated and linearized in a rugged aluminium die cast casing. The data is transmitted via the CAN bus to a central evaluation unit.

• CAN protocol: CANopen CiA 404
• Alu die cast casing, protection class IP66
• Indication of device state and errors via 2 bi-color LEDs
• Acquisition from one analogue input at a resolution of up to 16 bit for standard signals ±10V, 0-20mA and 4-20mA
• Anti aliasing filter
• Module monitoring via heartbeat function
• Automatic start-up
• Expanded ambient temperature range of -40°C…+85°C
• Mechanic shock resistance of up to 40 G (optional)
• Vibrations resistant from 3 .. 800 Hz @ 4.5 Grms (optional)

Connectivity

One analogue signal may be connected; the optional scaling of measurement units is parameterized via CAN bus.

• Voltage: – 10V .. +10V
• Current: 0 .. 20 mA
• Current: 4 .. 20 mA

Communications

The digitized analogue values of the µCAN.1.ai-BOX are transmitted via CAN bus. The bit rate of the CAN bus interface is adjustable within a range of 10 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 11 bit identifiers (CAN 2.0A) and 29 bit identifiers (CAN 2.0B) may be used on the process data.
