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.

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.)
Applications
Automated Test Equipment
Meter reading systems
Medical equipment
Battery monitoring
Multiplexers
