Product Description

• The Phoenix Contact PR2-BSC2/4X21 relay base with REL-IR/LDP-24DC/4X21AU industrial relay provides a convenient plug-in electromechanical switching assembly for compatible 24V DC industrial control circuits.
• The main PR2-BSC2/4X21 relay base, manufacturer part number 2833563, is designed to mount on a 35mm DIN rail and accept compatible Phoenix Contact REL-IR industrial relays.
• Installed in the base is the Phoenix Contact REL-IR/LDP-24DC/4X21AU relay, part number 2834096, which features a 24V DC operating coil and four changeover contacts.
• The four independent changeover contacts allow a single control signal to switch multiple compatible external circuits. The relay's hard gold-plated silver-nickel contacts are suitable for switching applications that require reliable contact performance at appropriate load levels.
• The installed relay supports a maximum switching voltage of 250V AC/DC and a limiting continuous current of 5A. Its minimum switching ratings are 1V and 1mA. Actual permissible loads must follow the manufacturer's electrical and application-specific limits.
• The integrated freewheeling diode suppresses coil-related voltage transients in compatible DC control systems. Correct coil polarity is required, with A1 connected to the positive supply and A2 connected to negative.
• The relay features a status LED for indication of coil energization, a mechanical contact-position indicator, and an integrated manual test button for supported commissioning and diagnostic functions.
• The green PR2 relay base incorporates screw-terminal electrical connections using M3 clamping screws. It accepts compatible solid and flexible conductors from 0.2mm² to 2.5mm², equivalent to 26–14 AWG for suitable single-wire connections.
• The base is designed for DIN rail mounting and allows the installed plug-in relay to be serviced or replaced using compatible components.
• The relay base itself has nominal electrical ratings of 300V AC/DC and 12A. These ratings apply to the socket and do not override the lower ratings of the installed electromechanical relay.
• The included REL-IR/LDP industrial relay has a manufacturer-rated mechanical service life of approximately 50 million switching cycles under specified conditions. Its electrical service life varies according to connected load and switching frequency.
• This relay assembly is suitable for industrial control panels, machinery automation, electrical cabinet construction, signaling circuits, and maintenance of compatible Phoenix Contact relay installations.
• The assembly includes the matching relay already installed in the base, providing the primary components required for a compatible plug-in relay installation.
