FAQ

This relay is designed to be used with Finder's 94 series sockets, such as the 94.04 (screw terminal) or 94.84.3 (screwless terminal) models for panel or 35mm DIN rail mounting.

No, the coil is specifically rated for 220V DC (Direct Current). Applying AC voltage will likely damage the coil and cause the relay to fail. The contacts, however, are rated to switch AC loads up to 250V AC.

4PDT stands for "Four Pole Double Throw". This means the relay contains four separate, electrically isolated switches. Each switch (or pole) has a common terminal that connects to one of two other terminals (the "throws"). This is also known as 4 changeover (CO) contacts, making it highly versatile for controlling multiple circuits simultaneously.
