Valve Control Board (Electronic Expansion Valve)
Product Details
| This valve control board is used in conjunction with the corresponding three-way controller. It can regulate the opening of electronic expansion valves by outputting either a 0–10 V proportional control signal or a 0–10 V motor speed control signal. When controlling electronic expansion valves, it can simultaneously manage up to four valves (options 1 through 4). When requiring a 0–10 V control signal, it can output up to eight independent 0–10 V voltage control signals (options 1 through 8). Additionally, it can acquire 12 channels of analog temperature signals and four channels of 0–5 V pressure signals (with the option to configure these as temperature signals as well). |
| Depending on the control object and the number of requests, different addresses can be configured to enable online operation. |
| Two RS485 communication ports are reserved, supporting the standard MODBUS communication protocol. |
| External dimensions: 129 mm × 98 mm. |
