The BT301S Variable Speed Peristaltic Pump delivers a flow range of 0.005 to 1750 mL/min, featuring variable pump heads and tubing. Beyond essential functions like reversible direction, start/stop, full speed (for rapid cleaning), and speed adjustment, it also offers a Time Dispense Mode and Anti-Drip function. Equipped with an RS485 MODBUS interface, the pump can be seamlessly controlled by external devices, including computers, human-machine interfaces, or PLCs.
Functions and Features
- 128Ă—32 dot-matrix LCD display offering intuitive status display and easy parameter configuration.
- Comprehensive operational controls including reversible direction, start/stop, full-speed mode, speed adjustment, and power-off memory.
- Supports soft start and gentle stop functions, as well as a Time Dispense function for precise dosing.
- An external logic level signal can control start/stop, direction, and dispensing functions, while external analog signals can adjust the rotating speed. The signals are optically isolated for enhanced protection.
- Wide voltage input (5–24 V) enables flexible support for external control signals.
- Selectable speed signal type (voltage or current) via the control panel.
- RS485 communication with MODBUS protocol, allowing configurable parameters for seamless integration with PCs, HMIs, or PLCs.
- Conformal-coated printed circuit board provides effective protection against dust and moisture.
- Excellent anti-interference capability and wide-voltage design ensure stable operation in complex power environments.
- Durable ABS engineering plastic housing with a streamlined and aesthetically pleasing design.
- Optional Accessories:Â foot switch, pulse damper, leakage detector.
