M211-L
1 Form A
Solid State Relay
DESCRIPTION
The M211-L is a bi-directional, single-pole, single-throw, normally open multipurpose solid-state relay in a miniature 4-pin small outline
package. It is designed to replace electromechanical relays in general purpose switching applications. The relay consists of an integrated
circuit that drives two rugged source-to-source enhancement type DMOS transistors - optically coupled to a light emitting diode. This
device also includes current-limiting circuitry. During increased load currents or transient current spikes, this circuitry acts to bring the
current down, protecting downstream components.
