PS12 Series High Performance Solid State Relays
AC solid state relay for loads up to 10A @ 250Vrms
Product Facts
IApproved to DSCC drawing
86031.
IOptically coupled all solid
state relay.
ITTL compatible input.
IZero voltage turn-on for low
EMI.
ICustom power package with
screw terminals.
The PS12 series solid state
relay is designed for AC
power switching up to 10
amps at 250Vrms. The cir-
cuit employs back-to-back
SCRs with zero voltage
turn-on for reliable switch-
ing of resistive or reactive
loads. TTL compatible input
circuitry is optically isolated
to 1,500Vrms from the AC
load circuit. The relay is
offered in two versions: the
PS12-1Y with “Y” level
screening per Mil-R-
28750C, and the PS12-1W
screened per Tyco
Electronics specifications for
CII relays, equivalent to
former “W” level of Mil-R-
28750.

Notes
1. Operation at elevated load currents up to 10 amps is dependent on the use of suitable heatsink to limit junction temperature.
2. Heating of output chips during and after a surge may cause loss of output blocking capability until junction temperature falls below maximum rating.
3. Internal snubber network is provided across output chips.
