Introduction: The four-channel push-pull mode syringe pump is mainly used in the laboratory, and the controller and actuator are in a split structure. The relatively independent actuators are easy to install and combine at will, which greatly adapts to the different operation needs of the users; the powerful system control functions enable the realization of a wider and more complex work task, which is suitable for the experimental needs of various application fields. Main function of the system Features: 1. Parameter setting function: Different working parameters can be set for four channels respectively 2. Parameter storage function: save the operating parameters of each channel 3. Operation control function: can control each actuator to work separately, or control up to four actuators to work at the same time or work in time. 4. Channel copy function: allows all channel actuators to work according to the parameters of the copy channel 5. Delay start function: can separately control the delay time of the start of the operation of each channel 6. Power-down memory function: After power-on, you can choose whether to continue working according to the state before power-off. 7. Traffic jam protection function: When an actuator is stopped or pumped due to an accident, the system whistle alarm and stop working. 8. External control function: There is a signal for external start and stop control. The signal is pulsed, and each time it is triggered, the start and stop state is changed once. 9. Each channel has two OC gate outputs to indicate the start and stop and direction of the actuator of the channel. 10.Communication function: It has RS485 communication interface, which can be controlled by the host computer in the background. 11. Syringe protection function: Prevent syringe damage by adjusting the position of the limit block Technical Parameters: Working mode: injection, extraction, first injection, first extraction, injection, continuous Number of execution units: 1-4 Maximum stroke: 90mm Stroke resolution: 0.165μm Line speed range: 7.94μm/min-79.4mm/min (flow rate = line speed × cross-sectional area inside the syringe) Line speed adjustment resolution: 7.94μm/min Stroke control accuracy: error ≤ ± 0.5% (stroke ≥ 30% of the maximum stroke) Rated linear thrust: >90N Syringe selection: built-in main manufacturer, main model syringe for selection Syringe Customization: Stores four user-defined syringe internal values Flow Correction: Get a more accurate volume through the calibration procedure Operation parameter setting: dispense liquid volume, injection time, extraction time, interval time, number of allocations, etc. Each channel can be set separately, allowing all channels to adopt the parameters of the specified channel. Start parameter setting: each execution unit is started separately, each execution unit is delayed, and each execution unit is started synchronously. Display parameter selection: volume, flow or line speed Power-down memory: After power-on, you can choose whether to continue working according to the state before power-off. Fast forward (back) function: full speed injection or liquid extraction Status signal output: 2-channel OC gate signal output for indicating start/stop and direction status Control signal input: 3 TTL level signal inputs for controlling start-stop, fast forward, fast reverse Communication interface: RS485 Controller dimensions: 235 × 178 × 74 (mm) Controller weight: 0.8kg Execution unit dimensions: 245 × 100 × 95 (mm) Execution unit weight: 1.3kg Use power: AC 90V-260V/40W Working environment temperature: 0°C-40°C Working environment relative humidity: <80%
