1 [2] [«Back ]   Click to Enlarge TEMPERATURE CONTROL TRAINER. MODEL IBL-30 This temperature control trainer is a Microprocessor based instrument. This is an ON-OFF controller. This module must be connected to Microprocessor trainer Model MPT-85 or MPT-J-85 or MPT-86 or MCT-31/51 when you want to program at machine level. This trainer has provision to connect to IBR-1. This card is used as an ADD-On interface card, when you want to use higher level language like, C / C++, VB, or VC++ etc. The purpose of this trainer is to provide an experimental setup for the student to learn as an ON-OFF control, and experiment how a Microprocessor is used to log (acquire) analog data from the thermocouple, convert that to digital value using ADC, set an upper and lower cut-off points (temperatures) for ON-OFF control action, and display the converted data in the form of packed BCD format so that the display shows the actual temperature in terms of degree centigrade on Microprocessor?s display. This trainer has necessary signal conditioners, Instrumentation amplifiers, buffer amplifiers, room temperature compensator, and calibration multi-turn potentiometers for adjusting zero and span temperature. It has a 230V AC operated solid-state relay, which is used to switch OFF/ ON the relay. This is a programmable 230V AC outlet. You can connect 350Watt mini immersion heater at this socket. A ? Lt Boro-silicate glass beaker contains water, in which the water is immersed. The temperate of the water bath is measured using a mercury thermometer for cross verification. This is supplied along with this trainer. It is necessary for you to read the description of the equipment?s input output terminals, functions of each block and understand them before actually connecting the instrument. After this stage it is necessary to read the actual program for understanding software functions used in the actual program. Microprocessor programs are supplied along with this trainer.

See Enlarge Click to Enlarge MATERIAL HANDLING PLATFORM TRAINER. MODEL IBL ? 16 Material handling in any automated production plant is a common site. The materials to be handled may be bottles, packets, metallic pieces, sub-assemblies, etc. In order to provide a similar feature, the material handling experimenter is designed. This demonstration unit consists of a) a stepper motor, with an unending continuous conveyor belt rotating over a free wheel. The shaft of the motor drives the belt. b) A proximity switch is placed looking over this moving belt, to detect any moving object. The output of this transducer is the feedback to the trainer. c) A programmable relay operating a motor is available as a controller for controlling an external 230V AC motor. The above setup is connected to the Microprocessor trainer, Model MPT-85. By programming the trainer, various schemes can be simulated. For example; a) counting of parts moving on the belt, b) switch OFF external motor, on detecting a part moving on the conveyor, c) make the conveyor move until the next part arrives near the proximity sensor and so on. This is a practical application simulator. Specifications: 3Kg/Cm2 Stepper motor supplied. Built-in power supplies. Interface electronics included. An unending belt moving on a freewheel mechanism, driven by the motor. A proximity sensor with a detection range of 5mm. Relay which can operate a 230V AC device operating @ 250mA Note: This experimental module can be interfaced to all Microprocessor trainers, Micro control trainers or IBM PC Add ? on card Model: IBR-1. See Enlarge Click to Enlarge LIQUID LEVEL CONTROL DEMONSTRATOR. MODEL IBL-23 This demonstrator is an ON-OFF control interface instrument to Microprocessor trainer. It is intended to demonstrate how a Microprocessor controls the water level in a tank. This instrument consists of a 2-4 liter water tank. The ON and OFF of the pump is controlled by a 230V AC operated relay under program control. Two sensing electrodes monitor a bi-level i.e. lower level and upper level. The height of these electrodes is adjustable within the tank's limit. Control program identifies the status of these electrodes and switches ON or OFF the pump. A manual drain cock drains water from the tank, by turning the wheel valve. This is required to simulate the fall in water level. Specifications: Adjustable Bi-level sensing electrode. 2-4 liter water tank, with drain facility. Relay operated special purpose water pump Necessary couplings and tubes. Built-in power supplies. Note: Microprocessor trainer MPT-85 or IBM PC add-on card model IBR-1 is required. See Enlarge Click to Enlarge FLEXIBLE MANUFACTURING TRAINER. MODEL IBL-31 This is a flexible manufacturing system trainer. The purpose of the system is to sort out the wooden pieces and metal pieces, which are moving on a conveyor belt by a program. In order to facilitate this, the following are built into the system. They are a) There are two 12 inch conveyor belts. Each belt moves in the opposite direction of the other belt. b) Two programmable pneumatic pistons with 5 inch travel. c) Optical source to detect either metal or wooden moving parts on the conveyor belt when the light beam is cut. d) A metal detector transducer to detect the metal part moving on the conveyor belt. e) An external compressed air at 5Kg/cm2 is required to activate the pistons. In order to accomplish this task, the flexible manufacturing system is used. For that we need belt conveyor, which is driven by a motor in which the metal and wooden piece move. In order to sort out the metal piece we need a PROXIMITY transducer & OPTICAL transducer and piston to push the pieces for further rotation. Piston is basically a pneumatic one, for which we need a compressor to actuate the piston, to move the test piece forward for further rotation. Principle of Operation: - The test pieces (both metal & wooden) will move through belt conveyor driven by a motor in the system. First the test piece will pass through the OPTICAL transducer basic principle of transducer is whenever light from the source is obstructed by any object it goes to high state. If any test piece obstructs the light path to transducer from the source it gives signal to piston & piston will move the test piece for further rotation Once moved on to the other belt it will reach the PROXIMITY transducer. Transducer will differentiate the metal piece from the other pieces. Range of detection is about (0 - 5) mm. If it is above the range transducer will not detect metal parts. NOTE: This can be used with PLC trainer also. This trainer provides very good scope to understand how automation process can be designed. See Enlarge 1 [2] [«Back ] Go to Top
