Product Name
125760-01 Allen-Bradley SLC 500 Industrial Terminal Base Module (Core Function: As a “wiring interface and mechanical support unit for SLC 500 I/O modules”, it provides secure terminal connections for field wires (e.g., sensor/actuator cables) and acts as a mounting platform for Allen-Bradley SLC 500 I/O modules. It supports easy module insertion/removal (hot-swappable with compatible I/O), simplifies wiring maintenance, and ensures reliable signal transmission between field devices and the SLC 500 PLC system.)
2. Product Description
The 125760-01 is a dedicated terminal base module designed for Allen-Bradley’s legacy SLC 500 series PLCs, featuring three core advantages: “seamless SLC 500 I/O compatibility, robust wire termination, and tool-less maintenance”. In industrial automation scenarios relying on SLC 500 systems (e.g., manufacturing assembly lines, material handling equipment), I/O modules require a stable interface to connect field wires—traditional terminal blocks often lead to messy wiring and time-consuming module replacement. This terminal base solves these issues by integrating a standardized socket for SLC 500 I/O modules (e.g., 1746-IB16 digital input modules) and clearly labeled terminals for field wiring, streamlining installation and reducing wiring errors.
Its key strength lies in user-friendly design and mechanical durability: it uses screw-clamp terminals that accept a wide range of wire gauges (14~22 AWG), ensuring secure connections even in vibration-prone environments (e.g., near motors or conveyors). Unlike generic terminal blocks, it features a “keyed” design that prevents incorrect insertion of SLC 500 I/O modules, avoiding damage to both the module and base. It also supports hot-swapping of compatible I/O modules—maintenance teams can replace faulty I/O modules without disconnecting field wires, minimizing downtime (critical for 24/7 production lines).
For harsh industrial conditions, the module is constructed from flame-retardant polycarbonate (UL 94 V0 grade) that resists dust, oil, and moderate chemical exposure, complying with NEMA 1/IP20 protection (suitable for control cabinet installation). It mounts directly to standard DIN rails (35mm) or panel surfaces, adapting to common SLC 500 cabinet layouts. Typical applications include wiring support for SLC 500 digital input modules in automotive part manufacturing, terminal connection for analog I/O modules in food processing equipment, and mechanical support for I/O modules in warehouse automation systems—making it an essential accessory for maintaining and upgrading legacy SLC 500-based automation systems.
