The maximum lengths of the connection cables are as follows:
- power supply: 10 m (32.8 ft)
- analogue inputs: 10 m (32.8 ft)
- power supply for transducer analogue inputs 4-20 mA: 10 m (32.8 ft)
- digital inputs: 10 m (32.8 ft)
- analogue outputs 0-10 V: 10 m (32.8 ft)
- phase cutting analogue outputs: 10 m (32.8 ft)
- PWM analogue outputs: 1 m (3.28 ft)
- digital outputs: 10 m (32.8 ft)
- INTRABUS ports: 10 m (32.8 ft)
- RS-485 MODBUS ports: 1,000 m (3,280 ft); see also the MODBUS manual "specifications and
implementation guides" available on http://www.MODBUS.org/specs.php.
- USB port, 1 m (3.28 ft)
Use cables of an adequate section for the current running through them.
For EV3 HRV cabling we recommend using the CJAV39 connection kit (to be ordered separately). For
EVD HRV cabling instead, we recommend using the CJAV38 connection kit (to be ordered
separately).
