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.
