This module is a bi-directional SPSD(single-pole, single-throw), normally open solid state relay(SSR). The Grove Optocoupler Relay (M281) offers very low on-resistance, which allowing a high load current rating.
Unlike the other TRIAC SSR in our website, this relay is based on MOSFET, so it can carry both AC load and DC load. If you need to use a SSR with the DC load, this is what you want!
Low on-resistance(0.5Ω MAX.)
1A continuous load current
60V load voltage rating
Low input control current(3mA TYP.)
High input-to-output isolation(1.5kV MIN.)
Cost-effective: Usually, the price of a single-channel SSR will exceed $10, and the price of this module is less than half.
