OPTO 22 MP240D4 DC Control Relay

The MP240D4 is a DC control solid state relay featuring rugged epoxy encapsulation, a single-pole, normally open contact, and zero crossing switching mode. It has through-hole terminals and is designed for PCB mounting with a low profile. This relay undergoes full load testing and can withstand surge currents six times its rated current both before and after encapsulation. It utilizes advanced heat-spreader technology for efficient thermal management. The relay is hermetically sealed, provides 4000 Vrms optical isolation, and has a maximum output voltage dropout of 1.6V. It dissipates 1.2W and operates within a temperature range of -40°C to 100°C. Suitable for industrial applications.
