PID-S1 Four Loops PID Digital Controller Teaching Equipment Process Control Trainer
As with the present generation of PID controllers, the Four Loops PID Digital Controller mod. PID-S1 has a structure based on a high performance microcontroller, analog inputs and outputs, programming of the regulation functions and serial interface for the communication with Personal Computers. TRAINING PROGRAM: The equipment allows a wide range of educational applicationssuch as: • Analyzing the structure of a digital process regulator • Programming the functions of the regulator; • Analyzing the parameters: proportional, derivative andintegrative coefficient; • Analyzing the analog I/O signals and the connections withthe process regulation; • Applying algorithms to the functional programming of adigital process control; TECHNICAL SPECIFICATIONS: • Front screen in isolating material with screen-printeddiagrams and internal components • Power supply unit 24 Vdc / 2 A with electronic protectionagainst overload and short circuit • Power supply unit 10 Vdc / 0.5 A with electronic protectionagainst overload and short circuit • 4 different regulation techniques: - Multi Loops (1 to 4 loops) - Ratio - Cascade - Override When selecting a technique, the system automatically setsthe corresponding parameters and gives some I/O specificfunctions. • Color graphic TFT touch 4.3” display(480 x 272 pixels / colors: 16 M) • Auto-tuning • Alarm configuration page • Alarm history • Parameter page of the selected loop • Trend page of the selected loop • Parameter page of the analog inputs • Parameter page of the analog outputs • Parameter page of the digital I/O • Status and forcing of I/O • Time register • Ethernet switch: on board • Ø 2 mm jacks for instruments for connecting inputs andoutputs to external devices Analog inputs • 6 Voltage / current sortable analog inputs • Voltage range: 0÷1 V / 0÷5 V / 1÷5 V / 0÷10 V • Current Range: 0÷20 mA / 4÷20 mA Digital inputs • 8 optocoupled Auxiliary ON/OFF inputs (0-24 Vdc) Set Point • Local setting via the touch screen display Analog outputs • 4 voltage / current sortable analog outputs • Voltage range: -10 V÷ +10 V / -20 V÷ +20 V / 0÷10 V • Current Range: 4÷20 mA Digital outputs • 8 digital outputs 24 Vdc - 0.5 A Communication • 1 Ethernet interface for parameterization / supervision viaPC of the regulator with Modbus TCP/IP protocol.
