Yokogawa 16114‑500 / 16114‑5006 Modulack Module Card Rack

The Yokogawa 16114‑500 and 16114‑5006 form a complete Modulack rack assembly for Yokogawa ProSafe‑PLC safety instrumented systems. The 16114‑500 is the main mechanical chassis, while 16114‑5006 serves as the integrated backplane bus unit, providing slot positions, power distribution and high‑speed backplane communication for safety CPU and I/O modules.

This rack assembly supports hot‑swap insertion of safety modules and provides 24 VDC bus power for each slot. It meets functional‑safety mechanical requirements, with reinforced shielding against EMI interference. Designed for 19‑inch cabinet mounting, it runs continuously in petrochemical, refinery and power‑plant SIS safety cabinets.
