Description
The PLA140 is a single-pole normally open
(1-Form-A) Solid State Relay that uses optically
coupled MOSFET technology to provide 3750Vrms of
input-to-output isolation.
MOSFET output switches, which use IXYS
Integrated Circuits Division's patented OptoMOS
architecture, are controlled by a highly efficient
GaAIAs infrared LED.
The PLA140’s combination of low on-resistance and
high load current handling makes it suitable for a
variety of industrial applications.
Because Solid State Relays like the PLA140 have no
moving parts, they offer faster, bounce-free switching
in a more compact surface mount or though hole
package than traditional electromechanical relays.
