INDUSTRIAL PROCESS CONTROL TRAINER MODEL IBL – 16

Features and Details

• Annunciator: 12 numbers of annunciators are provided. This is a lamp display of 1″x2″ in size, intended to display status of critical functions in a given process. This is illuminated under program control by software.
• Switch simulator: 12 numbers of software polled binary switches are provided. These switches stay in their position unless changed again. These are used in conjunction with operative programs. These are used to design, inter-lock of a process, or as inputs while designing Programmable Logic Controller (PLC), or to change the sequence or process by the flick of toggle switch etc.
• Key switches: 8 numbers of software polled momentary key switches function similar to switch inputs except that, these switches come to their original position on release.
• BAR GRAPH display: 4 independent BAR GRAPH displays are provided. These are analog displays. These indicate the status of a process parameter in terms of display, of temperature, pressure, displacement etc., by displaying a group of LEDs. These are activated by connecting them to outputs of Digital to Analog converters or from an external instrument whose output is not more than 2.4 V DC FSD.
• DOT BAR display: 4 independent DOT BAR displays are provided. These function in the same manner as BAR GRAPH displays, except glow of one LED from starting position indicate the status of process.
• Analog simulators: 16 independent analog outputs are available. The variable output voltage (0 to 5v) of each channel can be set, by adjusting the respective pot, and stays there unless adjusted again.
• Buzzer: software controlled Piezo buzzer provides audio annunciation to set an alarm condition.
• Batch counter: software controlled Electro-mechanical batch counter is provided. This can be reset at the beginning of a process to zero. As the events take place, the counter keeps counting. This stays in its present position, even if the power fails. Count can go from 0 to 999.
• Preset switch: 2 digit-preset switch is provided. This can be preset to any value from 0 to 99. This is used for comparison to flag the end of an event. This can be logged by program.
• Current meters: There are two current meters with 20mA FSD, displayed digitally. These are used to measure current of any transmitter or receiver of any process instruments or hardware.
• Voltmeter: One digital voltmeter is provided. Range can be set for 2,20 or 200V DC FSD. This is used to test voltages in the instrument during experimentation.
• 8 Nos. of software controlled, high-tension relays are provided. To each relay, a 220V AC @ 1Amp, operated devices can be connected. 8 independent devices can be connected in the instrument. They can be a water pump, blower, solenoid, contactor, etc.
• High speed (35uSec), 16 channel, analog inputs can be connected to the instrument. The input can be either 16 channel uni-polar (positive) input voltages or 8 channel bi-polar ?5V input voltages can be connected. This is a 12-bit resolution, analog to digital converter. The analog inputs to the instrument may be from any analog transducer. The transducer may be LVDT, Strain gauge, Load cell etc. After proper signal condition.
• Slow speed (30Conversions/second), 16 channel, analog to digital converter is provided. The input can be uni-polar or bi-polar as indicated above. The nature of the inputs to these can be from a thermocouple, where the temperature variations, are very slow can be connected. For that matter, any slow response activated transducers can be connected as input to these terminals.
• Medium speed (100uSec), 16 channel analog input or 8bit resolution is also available. The input voltages for this can be 0 to 5V DC. The purpose of this is same as stated above.
