Advantages of the 70S2 Series
• Small Packages
Ideal for Tight Designs..
• Eight Different Packages
Wide Choice of Design Options.
• Optically Isolated
Input Isolated from Output.
• Zero Cross Switching
Reduced Current Surges for Most Loads.
SECTION 4
• Internal Snubber
Excellent Transient Protection.
Since acquiring this line of
miniature SSRs from Grayhill,
this product has continuously
evolved both functionally and
visually. The 70S2 Series
relays are designed for medi2.3
um-power loads. The design
(57.7)
incorporates a triac output
for SECTION A - A' and MOSFETs
AC loads
for DC loads. The 70S2
Series relays use optical isolation to protect the control
from transients. The 70S2
compact package is available in a combination of
screw, fast-on or PCB terminals. Its compact size makes
it ideal for designs where
space is limited. The 70S2
A'
Series relays have excellent
thermal performance.
