3.1.3.4 CURRENT MEASUREMENT AND CAN2, CONNECTOR CN104
Connector CN104 can be used to connect Current sensor and Slave 6.
Following current sensors are possible:
- Shunt based sensor with isolated CAN interface from ACTIA I+ME GmbH
- Current compensation sensor from Vacuumschmelze
Other sensors with analog output may be used only with proper replacement of some
resistor elements; proper software provided.
