µCAN.4.ao-BOX

µCAN.4.ao-BOX — 4-channel analogue output (voltage / current)

The decentralized module µCAN.4.ao-BOX features four analogue outputs which optionally provide a voltage signal (±10 V)
or a current signal (0–20 mA). The digital process value is scaled to an analogue output signal in a rugged aluminium
die-cast casing. The CAN interface supports CANopen and J1939 protocols.

Features

Due to its rugged casing with protection class IP66 the µCAN.4.ao-BOX is ideally suited for field use. The analogue signals
are transmitted a short distance to the sink, avoiding errors of analogue signals. Via the CAN interface the module can be
fully configured and the analogue variables are output.

• 4 independent analogue outputs
• Precise 16-bit D/A converter
• Standard signals: ±10 V, 0–20 mA and 4–20 mA
• Accuracy (voltage output): 1 mV
• Accuracy (current output): 1 µA
• Device state indication via 2 LEDs
• Extended ambient temperature range: −40 °C … +85 °C

Connectivity

Up to four analogue signals may be output; the signal type (voltage / current) is parameterised via CAN bus.

• Voltage: −10 V … +10 V
• Current: 0 … 20 mA
• Current: 4 … 20 mA

Communications

The digital output values are transmitted to the µCAN.4.ao-BOX via CAN bus. The CAN bus bitrate is adjustable from
50 kbit/s to 1 Mbit/s. A terminating resistor can be activated via a hardware switch. The module’s CANopen protocol
complies with CiA 301, CiA 305 and CiA 404. Both 11-bit identifiers (CAN 2.0A) and 29-bit identifiers (CAN 2.0B)
may be used for process data.
