1sna174856r2000 – rp22-048dc8a-1

Why Choose the TE Connectivity RP22-048DC8A-1 Relay 1SNA174856R2000?

The TE Connectivity 1SNA174856R2000, also identified as RP22-048DC8A-1, is an industrial vertical interface relay designed for switching and isolation functions in electrical control and automation systems. This compact relay module combines a 48 V DC control voltage with two changeover contacts (2CO / 2RT), providing a practical interface between control electronics and switched field circuits.

Designed for professional control-panel applications, the RP22-048DC8A-1 provides relay isolation while allowing a low-power control signal to switch external electrical loads. Its vertical modular format is particularly suited to organised control cabinets where efficient use of DIN-rail space and straightforward wiring are important.

The 1SNA174856R2000 provides a 5 A contact rating and a 48 V DC relay coil. Its dual changeover contact arrangement gives control engineers flexibility for switching, interlocking, signalling and interface duties in industrial machinery, process control and automation installations.

Reliable Relay Interfacing for Industrial Automation

Interface relays provide an important link between electronic control equipment and field devices. A control voltage applied to the relay coil operates electrically isolated contacts, allowing PLCs, controllers and other automation equipment to switch external circuits without directly carrying the switched load.

With its 48 V DC coil, dual changeover contacts and 5 A switching capability, the RP22-048DC8A-1 is well suited to signalling, interlocking and general-purpose control functions. Its vertical construction also supports compact and orderly installation within industrial control cabinets.

Typical Applications

• PLC and controller output interfacing.
• Industrial control and automation panels.
• Machine control circuits.
• Signal switching and electrical isolation.
• Interlocking and auxiliary control circuits.
• Process control and instrumentation systems.
