PLC PROCESS TRAINER MP131

A powerful bench combination to allow students to become familiar with the use and applications of PLC and to gain practical ladder logic programming experience and skills. Table top bench including a programmable logic controller based on an industry-standard PLC (2 models proposed in option). Its inputs and outputs are arranged on a clearly labelled and logically laid out front panel.

Ref MP131B: FUNCTION ON/OFF / TIMER / ANALOGIC CONTROL / PID CONTROL

 

Teaching objectives

 

Ref MP131A

  • To study automated control system associated to the hydraulic facilities (pump speed driving, level measurement, vessel draining, vessel stirring).

  • Identification of the sensors, actuators, process to control, signals processing.

  • Writing of a GRAFCET program.

 

Ref MP131B

  • MP131B model permits more other to study a control loop with the introduction of an analogical measurement and an analogical action.

  • To calibrate an analogical sensor and to study its linearity.

  • PID single variable control loop (pH):

    • Measurement of the input/output of the controller

    • Identification of the components (controller, actuator, sensor, process).

  • Definition of the variables :

    • Set point,

    • Measure,

    • gap variable,

    • Adjusting size,

    • Controlled size,

    • Disruptive size,

    • Algorithm Control (ON/OFF, PID)

 

Technical specifications

The system is made up of a mixing stirred vessel feed by two other vessels. Each vessel is equipped with an electric draining valve, a manual draining valve and a low level probe. The mixing stirred vessel is equipped with an additional high level probe.

This table top bench is made up of a stainless steel frame mounted on 4 feet with a PVC panel.

 

Ref MP131A

  • 3 vessels

  • 3 solenoid valves

  • 4 level detectors

  • A stirrer (motor and propeller)

  • A control cabinet including :

    • 1 section switch with lock

    • 1 emergency stop button

    • 1 rearmament button, 1 ON light , 1 start button and 1 cycle stop, 4 switches, the PLC wiring terminals

    • The control and the stirrer safety device

    • 1 transformer 24V, relay, solenoid valve, 1 contactor,1 DC power supply 24V for the PLC.

Ref MP131B

It is made up of the same components as model MP131A with the bellow additional components:

  • A pH control loop managed by the PID function of thePLC. It is made up of :

    • A pH probe measurement

    • A transmitter pH/I (4-20 mA),

    • A peristaltic pump in 110V, with speed driver

  • A feeding vat of the acid or the base
