Compact Relay Switching for Electronic Control and Industrial Automation

Miniature PCB relays provide a practical method of switching electrical circuits using electronic control signals. The Finder 30.22.9.048.0020 uses a 48 V DC electromagnetic coil to operate two changeover contact sets, allowing a control circuit to manage compatible electrical loads through physical switching contacts.

In a typical application, energising the relay coil changes the position of both changeover contacts. Each common terminal transfers from its normally closed contact to its normally open contact. When the coil is de-energised, the contacts return to their normal positions.

This 2 CO (DPDT) switching arrangement is useful where two circuits need to be controlled together or where an application requires both normally open and normally closed switching functions. Typical uses include electronic control boards, equipment interfaces, automation modules and signal-routing circuits.

Direct PCB mounting allows the relay to be incorporated into electronic assemblies without requiring a separate DIN rail-mounted switching device. The board layout must accommodate the relay's specified terminal arrangement, electrical clearances and mechanical dimensions.

When selecting the Finder 30.22.9.048.0020, designers should consider the connected load's switching voltage, steady-state current and inrush characteristics. Appropriate coil-drive circuitry and transient suppression should also be provided according to Finder's technical recommendations and the requirements of the complete electronic assembly.

Typical Applications

• Printed circuit board control assemblies.
• Industrial automation electronics.
• Electronic switching interfaces.
• Equipment control modules.
• Signal switching and routing circuits.
• Embedded electronic control systems.
• Building automation equipment.
• Electrical monitoring and control devices.
• OEM electronic equipment manufacturing.
• Replacement of compatible Finder 30 Series PCB relays.
