Encoder is light sensor that detects and converts mechanical transfer or displacement into electric signal. It detects the position, speed, angle by means of converting analog signal generated from a revolution of the shaft into digital signal by the internal fixed circuit.Output Circuit Types :1) Open Collector 2) Push Pull Output 3) Line DriverOutput Channels1. A,B PhaseThe output signal of A, B phase are output with 90 of phase difference. It is the signal to discriminate the rotation direction.2. Z PhaseOne Z phase is output per one rotation, which is called origin signal.Resolution (Pulses per Revolutions)

means the number of pulse which is output from 1 revolution of the rotating shaft of rotary encoder. In case of incremental encoder, it can be indicated in the number of rotating slits, in case of Absolute encoder, it can be indicated in number of divisions or bit High resolution from 100 to 6000 P/R Power Voltage : 5 VDC/24 VDCOuter Diameter : 30,40,48,58 mmShaft Diameter : 6mm, 8mm

Input (Control)

For the electrical heating system to control the temperature at the set point by switching contractors has many disadvantages, such as wear and tear, limited life of contractor, noisy operation. Besides these it has limited accuracy due to limitation of speed of operation, hence loss of power. All above mentioned disadvantages are eliminated by SCS Thyristor Controller.

Solid State Relays & Relay ModulesMaitry Instruments & Control offers wide range of solid

state relays. Solid state relay is a static electronic switch unlike in an electromechanical relay where switching takes place between two moving contacts, Switching in SSR takes place across the junction of semiconductor device. Devices are Triac or Thyristor for AC switching & Transistor for DC switching. In most SSRs galvanic separation is achieved by Optocouplers equipped with integrated trigger circuit. (optotriac) provide the switching function required for the corresponding load type.
