New products: Pololu Isolated Solid State Relay/Switch, SPST

We’re happy to announce our new Isolated Solid State Relay/Switch boards! These modules function as solid state, single-pole, single-throw (SPST) relays or switches that can be controlled by low-current signals between 2.7 V and 40 V. The control signal activates an optically coupled driver that turns on a pair of output MOSFETs, which keeps the outputs electrically isolated from the input side. The MOSFETs are arranged back-to-back to make the outputs symmetric and bidirectional (so the board can be used as a high-side or low-side switch).

These boards make good replacements for mechanical relays in many situations, since their semiconductor-based design allows them to avoid problems like contact wear and arcing that limit the service life of mechanical relays. They are also silent and generally much smaller than a typical mechanical relay with a comparable current rating. Two versions of the solid state relay/switch are available with different voltage and current capabilities:

• Pololu Isolated Solid State Relay/Switch, SPST, 30V, 11A
• Pololu Isolated Solid State Relay/Switch, SPST, 60V, 7A

Three-wire and two-wire (with EN and VIN tied together) control options for the Pololu Isolated Solid State Relay/Switch, SPST.

Introductory special discount! Use coupon code SSRELAYINTRO to get either version for $3.50 each.
