Yes. The PLC inside the load bank is connected to an industrial Ethernet switch (PoE type), supporting a standard 100 Mbps Ethernet connection.
The upper-level PC/SCADA system can connect directly to the RJ45 port of this switch.
Protections include:
- Overtemperature
- Low airflow
- Fan overload
Interlock: Local/Remote mode selection (mutually exclusive)
- Switch control mode to Remote
- Start fans
The register list will be provided after production is completed.
Approximately 5 minutes (controlled by PLC timer).
- Fans start: < 500 ms
- Contactor response: 50–150 ms
Minimum step: 1 kW
Default IP is typically set as: 192.168.0.1
For multiple units (e.g., 8 load banks), each will be assigned a unique IP.
Yes. When the load bank is running:
- If communication is lost,
- The PLC will safely ramp down and stop the load after a timeout.
Yes. The energy meter communicates with the PLC, allowing SCADA systems to read power data.
Yes. A digital energy meter is installed to measure total instantaneous power (including resistors, fans, auxiliaries).
No. Fans and auxiliary systems are controlled internally by the PLC.
However, the main power must be switched on locally before operation.
Yes. The resistive load setpoint (kW) can be written into a Modbus holding register.
The PLC will control the load accordingly.
Note: Fan power consumption is additional to the resistive load.
Yes. Communication is via RJ45 Ethernet using Modbus TCP, with the PLC acting as a Modbus slave/server.
Yes. Space can be reserved inside the control cabinet if required.
Available power supply:
- 24 VDC (standard)
- 230 VAC (optional, if specifically requested)
Please provide the converter model so we can verify installation space.
