DC OUTPUT SOLID STATE RELAY
DC Output Solid State Relay 10Amps 60V DC (Optically Isolated Input)
This project has been designed around TLP250/352 which is Opto-Coupler IGBT/MOSFET Gate Driver from Toshiba and Mosfet IRFP260 from IR, This relay consists of optically isolated gate driver and low impedance Mosfet. The combination of low resistance and high load current handling capabilities make this Relay suitable for a variety of switching applications. These devices are ideally suited for controlling high voltage and current DC loads with solid state reliability while providing 3750V isolation from input to output.
A solid-state relay (SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals. SSRs consist of a Opto-isolator which responds to an appropriate input (control signal), a solid-state electronic switching device which switches power to the load circuitry, and a coupling mechanism to enable the control signal to activate this switch without mechanical parts. This relay designed to switch DC Load up to 10Amps. It serves the same function as an electromechanical relay, but has no moving parts. Solid-state relays have fast switching speeds compared with electromechanical relays, and have no physical contacts to wear out. Input trigger voltage 3V to 9V DC (1.5V to 12 V with Transistor) and output load 10Amps and supply 12V to 60V DC (100V DC also Possible). Gate Driver required supply 12V to 18V DC. Heat sink required for peak load.
- NOTE 1: Q2, R1, J2 Are Optional for Low Current Trigger Signal Input
- NOTE 2: J1 (VC-J) Close In Case of Load Supply and Logic Gate Supply are same 12V to 18V DC for single supply input operation
- NOTE 3: Done use R4, D1 LED If Load Supply is higher than 24V DC
- NOTE 4: J3 for Cathode ground in case of single pulse input
