The ABB 500TRM02 (order code: 1MRB150011R0001) is a dedicated plug-in terminal base module exclusively engineered for the ABB AC500 PLC series, serving as the standard wiring and mounting carrier for all AC500 I/O, temperature and signal conditioning modules. It features a rugged industrial design with a detachable spring-type terminal block, enabling tool-free fast wiring and easy on-site maintenance—AC500 functional modules can be hot-plugged onto the base without disconnecting field wiring, significantly reducing system downtime during module replacement or troubleshooting. Built with precision mechanical interlocking and anti-reverse insertion design, it ensures accurate and secure connection of AC500 modules, avoiding wiring errors and module damage caused by incorrect installation. Fully compatible with all AC500 series slim-type modules (500MTM02/500ITM02/500BIM01/500AIM02), it adopts standard 35mm DIN rail mounting with a compact form factor, making it an essential auxiliary component for building neat, reliable and maintainable AC500 automation systems.

The 500TRM02 1MRB150011R0001 features a high-precision industrial mechanical design with integrated precision pin headers and socket connectors, ensuring stable and low-resistance electrical connection between the terminal base and AC500 functional modules. The one-click plug-in locking structure enables AC500 modules to be securely fastened to the base with a simple push and lock, preventing module disconnection caused by industrial vibration (5-50Hz, compliant with IEC 60068). It is designed with a mechanical anti-reverse insertion structure, which physically prevents incorrect installation of AC500 modules, avoiding pin bending and electrical damage caused by reverse plugging. The terminal base uses a reinforced plastic housing (UL94 V-0 flame retardant) with high mechanical strength, resistant to impact and high/low temperature deformation, and the surface is treated with anti-static coating to prevent static electricity from damaging module electronic components during installation and maintenance.

The 500TRM02 is equipped with a detachable spring-type terminal block that supports tool-free fast wiring—field wires can be connected by simply pressing the terminal button with a small screwdriver or finger, no special tools required, significantly reducing on-site installation time. The terminal block has clear laser-marked terminal numbers and wiring symbols, corresponding one-to-one with AC500 module signal pins, avoiding wiring errors in complex industrial sites. The detachable design allows the terminal block to be removed independently for off-site wiring and pre-configuration, and the wired terminal block can be quickly reconnected to the base, improving the efficiency of system pre-assembly and on-site debugging. Most importantly, AC500 functional modules can be hot-plugged on the terminal base without disconnecting field wiring, enabling on-site module replacement and troubleshooting without stopping the industrial system, minimizing production downtime caused by equipment maintenance.

The 500TRM02 1MRB150011R0001 is a universal terminal base fully compatible with all ABB AC500 series slim-type functional modules, including temperature measurement modules (500MTM02/500ITM02), digital I/O modules (500BIM01/500BOM01), analog I/O modules (500AIM02/500AOM01) and signal conditioning modules—realizing a unified wiring and mounting standard for AC500 slim modules, simplifying system design and spare part management. It adopts standard 35mm DIN rail mounting with a compact and slim form factor (80×100×40mm), which can be closely installed side by side on the DIN rail without occupying extra space, maximizing the utilization of industrial control cabinet space. The base is designed with integrated DIN rail locking clips, enabling fast and secure mounting without additional fasteners, and supports multi-base parallel installation for large-scale AC500 I/O system wiring. It has an IP20 front panel protection rating, preventing dust and accidental contact with live parts, meeting industrial control cabinet safety standards.
