Description
1. At-A-Glance Executive Brief
- Model: 16114-500
- Brand: Yokogawa
- Part Type: ProSafe-PLC Module Card Rack / Chassis
- Lifecycle Status: Mature / Legacy Safety System Support
- System Compatibility: Yokogawa ProSafe-PLC Safety Instrumented Systems
- Weight: Approx. 20.4 kg (Empty rack)
2. Technical Introduction
Physical damage to backplane connectors or power bus degradation inside safety instrumented systems often forces unplanned outages when safety processor cards lose reliable communication with I/O modules.
The Yokogawa 16114-500 solves this infrastructure vulnerability by providing a heavy-duty physical chassis and backplane bus specifically engineered for ProSafe-PLC safety networks.
This modular card rack distributes dual 24V DC power rails and internal communication signals across high-integrity slots, securing critical discrete and analog modules against mechanical stress and electrical noise in harsh industrial environments.
3. Core Technical Specifications
- Input Voltage: 24 V DC
- Current Rating: 12 A max per DC power bus (21 A max combined)
- Target Architecture: ProSafe-PLC safety instrumented systems
- Max Ambient Temperature: 60°C
- Hazardous Area Rating: Class I, Division 2, Groups A, B, C, D
- Mounting Style: Standard cabinet panel mount
- Weight: 20.4 kg
4. Field Engineer’s Tech Notes
- Backplane Pin Alignment: When installing replacement cards into this rack, verify that guide pins engage smoothly before applying terminal pressure. Forceful insertion can bend delicate backplane pins, causing intermittent communication dropouts on safety-critical channels.
- Bus Polarity and Grounding: Double-check DC power bus polarity prior to energizing the chassis. Reversing the 12A supply feed will damage internal backplane protection components, and failing to tie the frame to the cabinet ground bus introduces severe electromagnetic susceptibility into safety loops.
5. Adaptive QA & Testing Protocol
Every 16114-500 chassis undergoes comprehensive bench inspection to verify backplane trace continuity, pin integrity across all module slots, and isolation thresholds on the dual 24V DC power distribution buses. Technicians test voltage drop under simulated load conditions to ensure stable power delivery. Complete hardware verification logs and inspection videos are available upon request prior to dispatch.
6. Buyer’s FAQ
- What warranty is provided with this module rack?
All units carry a standard 12-month replacement warranty from the date of invoice.
- Is this chassis available as New Surplus or Refurbished?
We stock both factory-sealed New Surplus (NSFP) and fully tested refurbished racks depending on active inventory requirements.
- How fast can an urgent replacement rack ship to site?
In-stock orders process for same-day expedited freight dispatch to mitigate extended downtime during safety system overhauls.
