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.
