Solid State Relays

The zero switching relay with triac (10 A) or thyristor output (25 A, 40 A) offer a solution for resistive load switching. The zero switching relay switches ON when the sinusoidal voltage crosses zero and switches OFF when the current crosses zero. The LED indicates the status of the control input. The clip-on cover is securing touch protection to IP 20. Output terminals can handle cables up to 16 mm2.

Features:

• Zero switching AC Solid State Relay

The analog switching relay works in accordance with the phase angle control principle, i.e., the output switching point in the AC sine wave depends on the control input which can be either 4-20MA or 0-10VDC. 4 MA or 0VDC correspond to zero output power whilst 20 Ma or 10VDC correspond to full output power (near linear power response). The relay switches off every time the output current crosses zero, and switches on in accordance with the applied control input.

Features:

• AC solid state relay

• Variable intensity LED-indication according to input current
• Integral snubber network
• Polarized lockable control connector for safe connection for voltage controlled version

The solitron mini is a single-phase solid state contractor designed to replace electro-mechanical contractors in industrial heating and motor applications, especially when switching is frequent. The product is ready to mount on din-rail or chassis and comes with integral heat sink. The standard housing dimensions enable installation in limited space and the terminal layout allows both contractor (e) and ssr (u) type connection. Two 2. 5mm2 cables can be connected in each screw terminal to allow looping. A removable ip20 cover allows connection of a 4mm2 cable with crimped terminal. An led indicates the status of the control input. The superior heat-transfer efficiency combined with a robust power management system make this a high reliability  product that can meet the most stringent functional requirements.

The solid state relays RMD houses semiconductor thyristors and mechanical contacts that compliment each other. On applying the control voltage, thyristors are activated. After a short delay, an electromechanical relay is activated. This switching method protects the contacts of the electrome- chanical relay and reduces heating of the thyristors. The same principle applies during removal of the control input. The result is millions of trouble-free cycles in a compact and modular switching package.
