Phoenix Contact RIF-2-BPT/4X21 Industrial Relay Base (Product Code: 2900934)
The Phoenix Contact 2900934 is a premium, DIN rail mounted industrial relay socket base belonging to the renowned RIFLINE complete universal relay system. This base is engineered to accommodate plugin octal style industrial relays featuring either 2 or 4 PDT (changeover / PDT) contacts. Optimized for automation, protection, and control systems, it introduces time saving wiring innovations and multi channel density to electrical control enclosures and switchgear panels.
Key Features
-
Tool Free Push In Connection Technology: Designed with advanced Push In Spring Clamp terminal blocks that allow rigid wires or conductors with ferrules to be terminated simply by pushing them into the terminal. This cuts down assembly times significantly and ensures vibration proof connections.
-
Integrated Plug in Module Slot: Features a built in top channel designed to receive optional plug in input modules, such as status LEDs, freewheeling suppressor diodes, RC elements, or varistor overvoltage protective circuits.
-
High Electrical Capacity Layout: Capable of handling a robust nominal current of up to 12A depending on the specific relay assembly and temperature conditions.
-
Functional Compatibility and Flexibility: Universally accepts Phoenix Contact REL-IR2 (2 changeover) and REL-IR4 (4 changeover) industrial relay modules, giving designers flexible scaling pathways across various coil voltages (24V DC, 120V AC, 230V AC).
-
Symmetrical DIN Rail Fastening: Snaps securely onto standard 35 mm symmetric structural rails (NS 35/7,5 or NS 35/15).
