Relay Control System Trainer Manufacturer,Supplier and Exporter in India
Product Code : EL-PET-10247
Jlab Export is a leading Relay Control System Trainer Manufacturer,and suppliers in India
Relay Control System Trainer (code EL-PET-10247) is a control-systems trainer for studying on-off (relay) control, a nonlinear control method. A simulated electronic relay built with high-speed ICs works with a simulated second-order linear plant, and the relay’s dead zone and hysteresis are both adjustable. Jain Laboratory Instruments Pvt Ltd (JLab) manufactures the trainer in Ambala, India.

What Is the Relay Control System Trainer Used For?
It is used in control systems practicals on nonlinear systems, to show how a relay’s switching characteristics change the response of a plant that would otherwise behave linearly.
Frequently Asked Questions
What are dead zone and hysteresis in a relay?
Dead zone is a band of input around zero within which the relay does not switch. Hysteresis is the gap between the input level at which the relay switches on and the level at which it switches off again. Both affect whether a relay-controlled system settles or keeps oscillating in a limit cycle.
Why display x and x′?
Plotting a variable x against its rate of change x′ gives the phase-plane trajectory, the standard way to analyse relay and other nonlinear control systems; a limit cycle appears as a closed loop on that plot.
How does it differ from the Linear System Simulator Trainer?
The Linear System Simulator Trainer simulates linear first-, second- and third-order systems for time-response studies. This trainer places a simulated relay, a nonlinear element, in control of a simulated second-order linear plant.
Who manufactures this trainer?
JLab (Jain Laboratory Instruments Pvt Ltd) makes it in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana, where it manufactures control-systems trainers and other electronic lab instruments in India. The relay trainer is built in JLab’s own works, not resold from a trader, and is sold factory-direct to institutions, dealers and importers. JLab exports worldwide and ships to buyers in every region — for example Austria in Western Europe, Honduras in Central America and the Caribbean, Egypt in North Africa, Lesotho in Southern Africa and Denmark in Northern Europe.
