Ultra-slim solid state relay for industrial and appliance markets

18 April 2007 Switches, Relays & Keypads

Fujitsu Components Europe's ultra-slim solid-state relay device for the industrial control and appliance markets is designed for high-density PCB mounting. The FTR-SL is a 1 A, SIP-type solid state relay measuring 5 x 28 x 15 mm (W x L x H). It is pin-compatible with Fujitsu's existing FTR-LY electromechanical relay, thus expanding the types of relay mounting styles that Fujitsu offers for industrial and appliance applications, such as PLCs, process controls, remote switching, airconditioners, vending machines and photocopiers.

The FTR-SL series offers 5 V, 12 V, 24 V and 60 V d.c. nominal control voltages ranging from 3,75 to 66 V d.c. It can handle a 50 A surge and a peak voltage of 250 V a.c. As a standard feature, it includes a built-in varistor/snubber circuit to prevent malfunction from overvoltage and/or overcurrent. A zero-cross circuit, which minimises noise and inrush current, is also standard.

The FTR-SL has a 2500 V rms dielectric strength between input and output. Its semi-permanent operating life provides a maintenance-free solution.
