MODEL IBL-IM ? 12 Relay works under the principle of Electro-magnetic induction. An electric current passing through a coil wound on soft iron core. The iron core is magnetized as long as the current flows through the coil. As a result of this, a spring activated metallic contactor, is attracted towards this iron core, causing a mechanical movement. This principle is used to our advantage. There are two important principles demonstrated in this device, namely CAUSE & EFFECT. A relay connects two devices working in different electrical conditions. I.e. mechanically connected and electrically isolated. For example: A digital system works at 5V DC and a fan works with 230V AC. Because the current flowing through a coil from a digital system, operating at 5V DC energizes the iron core; there is an effect of movable arm of the relay shifting its initial position. These switches ON a 230V AC operated bulb. The function of a Relay module is to show how a Microprocessor program can operate the relays and actuate high power devices. Some of the devices that can be actuated are like 230V AC lamps, blowers, contactors, fans, solenoids etc., which require 230 V AC supply for energisation. There are two relays placed on this module, which can be programmed by the Microprocessor either for ON or OFF condition. Each relay is housed in a transparent enclosure, to enable a student to see the movement of movable arm of the relay, while it gets actuated. The student is benefited by observing this phenomena.

See Enlarge Click to Enlarge STEPPER MOTOR INTERFACE MODULE MODEL IBL-IM ? 14 Stepper motor is a DC motor. It differs with conventional motors, in the sense; stepper motor is used for positioning the rotor at a specified position. A sequential magnetization and demagnetization, enables the rotor of the motor to rotate on its axis by a fixed angle. If this is so, it should be possible to rotate only a few steps either in clockwise or anti-clockwise direction. For example: In a printer, a stepper motor controls the print head movement. A stepper motor can be used in any place where, a precise mechanical movement is desired. Stepper motor module, Model IM-14 is a single stepper motor module.
