3S-32-PA Intelligent Dual Pump Controller Panel, RS485 Smart Control Box

Agricultural irrigation systems: The Intelligent Dual Pump Controller Panel controls pump start/stop via cyclic timers or 24-hour timers, ensuring quantitative water supply for farmland.

Sewage lifting stations: Equipped with float switches, electrode probes, or 4–20 mA liquid level transmitters, the RS485 Modbus pump starter enables automatic start/stop and overflow alarms.

Catchment wells/municipal drainage pumping stations: Using liquid level relays, float switches, or liquid level transmitters, the Intelligent Dual Pump Controller Panel controls multi-level liquid level start/stop, ensuring urban drainage safety.

Secondary pressure-boosting water supply in high-rise buildings: Combined with 4–20 mA pressure sensors, the RS485 Modbus pump starter maintains constant pressure in real time to meet users’ stable water demand.

Water supply from underground pools to upper pools: Through float switches or liquid level probes, the Intelligent Dual Pump Controller Panel realizes automatic water supply between upper and lower pools.

Water extraction from deep wells to water storage tanks: With the help of float switches or liquid level probes, the RS485 Modbus pump starter ensures linkage between water pumping and storage, avoiding dry running and overflow.

Pressure tank boosting systems: Via pressure switches, electric contact pressure gauges, or 4–20 mA pressure transmitters, the Intelligent Dual Pump Controller Panel achieves pump start/stop and constant pressure control.

Fire pump systems: Using pressure switches or flow switches, the RS485 Modbus pump starter ensures the pump starts quickly and runs continuously in case of fire.

HVAC/industrial circulating cooling: Through timed switching, pressure or temperature sensors, it realizes cyclic operation and redundant backup of pumps.

Domestic/industrial drainage systems: Suitable for basement drainage and industrial wastewater treatment pools, often used in conjunction with liquid level signals and overflow alarm devices.

Implements periodic operation optimization and status adjustments to reduce the likelihood of failures and extend the service life of pumps and motors.

Responds immediately when a fault occurs, cutting off operation to minimize damage and ensure the safety of the system and personnel.

Wide power supply range: The Intelligent Dual Pump Controller Panel supports single-phase AC110–250V, three-phase AC220–415V (AC440–490V optional), and automatically adapts to 50/60Hz. It enables wide-voltage, cross-regional deployment, easily coping with power grid fluctuations and multi-country voltage standards.

Built-in 8 dual-pump operation modes (duty/standby, alternation, timing, parallel load sharing, etc.) to meet needs from entry-level to high-end projects. The RS485 Modbus pump starter  can quickly adapt to different water treatment scenarios without complex programming.

This Intelligent Dual Pump Controller Panel supports RS485 (Modbus RTU), IoT, WiFi, etc., and is compatible with PLC, BMS, SCADA, DCS, and HMI systems, enabling flexible upgrades and efficient remote management.

Self-learning current setting and automatic parameter calibration reduce errors from manual settings.

Stores 10 historical fault records for easy remote diagnosis.

The 3S-32-PA Intelligent Dual Pump Controller Panel, designed for compatibility and ease of use, simplifies installation and commissioning, reduces after-sales burdens, and helps assemblers and project providers complete more project deliveries in less time.
