1sna174855r2700 – rp22-024dc8a-1

Why Choose the TE Connectivity 1SNA174855R2700 RP22-024DC8A-1 Relay?

The TE Connectivity 1SNA174855R2700, product designation RP22-024DC8A-1, is an industrial electromechanical relay featuring a 24 V DC coil and two changeover contacts. Designed for control and interface duties, it provides reliable galvanic switching between control signals and connected electrical loads.

The relay uses a 2CO / DPDT contact configuration and is specified for switching currents up to 5 A. Its two independent changeover contacts make it suitable for applications where a single control signal needs to switch two circuits or provide both normally open and normally closed switching functions.

Part of the established TE Connectivity / ENTRELEC industrial control range, the RP22-024DC8A-1 is suited to control panels, machinery, automation equipment and interface circuits requiring a compact 24 V DC relay. It is particularly useful for replacement and maintenance of compatible legacy ENTRELEC relay installations.

Key Advantages

• 24 V DC coil suited to widely used industrial control voltages.

Flexible 24 V DC Relay Switching for Control Systems

Electromechanical relays allow a comparatively low-power control signal to operate separate electrical contacts while maintaining galvanic separation between the control and switched circuits. Changeover contacts are particularly versatile because each pole provides both normally closed and normally open switching paths.

With its 24 V DC coil and dual changeover arrangement, the RP22-024DC8A-1 can perform interface, isolation and control functions across two circuits from a single relay coil. Its 5 A switching capability makes it suitable for many industrial signalling and control loads when applied within the relevant circuit ratings.

Typical Applications

• Industrial electrical control panels.
• PLC and controller interface circuits.
• Machine and process automation.
• Control signal isolation.
• Alarm and signalling circuits.
• Replacement in compatible ENTRELEC relay installations.
