Subrack Structural Frame Alignment and High I/O Density Scaling
Engineered for 19-inch subrack integration, the carrier bar accepts connection units and modem modules while optimizing physical layout efficiency. Structural metal construction ensures chassis ground continuity across mounted field termination interfaces, supporting high I/O density scaling inside control cabinets. Solid metallic mechanical fastening prevents physical displacement and vibration decoupling, protecting backplane bus interface cables from stress or strain.
Frequently Asked Questions
Q: Does the DSRA 110 terminal carrier kit draw electrical power from the backplane?
A: No, the DSRA 110 is a passive mechanical mounting bar assembly with zero electrical power consumption.
Q: Can individual mounting bars be replaced without replacing the entire carrier kit assembly?
A: Yes, the structural mounting bar is available as an individual component under part number 21660566-22.
Q: How is chassis earth grounding achieved across mounted terminal modules?
A: Metallic contact surfaces on the carrier kit bond mechanically to the main enclosure frame when retaining fasteners are tightened, establishing earth grounding continuity.
Field Installation Guidelines
- Verify subrack cabinet dimensions match the 19" x 3S mounting specification before positioning the carrier kit.
- Align the mounting bar side flanges with the cabinet rack guide holes and insert M6 fixing bolts.
- Torque all mounting screws to standard engineering specifications to secure structural rigidity and chassis ground contact.
- Mount connection units or modems onto the carrier bar, ensuring locking latches are fully engaged.
- Maintain a minimum physical separation distance of 200 mm between low-voltage modem/signal wiring and AC power distribution cables.

Tech & Buying Guide
The Shift to Flexible IO Modules in Modern Industrial Automation
Traditional control systems rely on dedicated Input Output (IO) cards for industrial automation. Each conventional module processes a single signal type, such as Digital Input (DI), Digital Output (DO), Analog Input (AI), or Analog Output (AO). A standard 16-channel card accepts only one specific channel type across all ports. This inflexible hardware design often creates severe engineering bottlenecks during project execution. Engineers frequently must install entirely new cards to accommodate a single extra sensor. Consequently, late design changes increase control cabinet space requirements and drive up project costs.
DCS Commissioning Steps in Industrial Automation Projects
Commissioning a Distributed Control System (DCS) represents a crucial milestone when deploying modern process automation infrastructure. Field engineers must execute systematic verification steps to transition complex control hardware from static installation to dynamic plant control. Proper commissioning ensures that controllers, I/O modules, network switches, and HMI software operate in strict compliance with engineering design specifications before introducing live process fluids.
PLC and DCS Control System Spares Strategy: Engineering Guidelines
Modern factory automation relies on high-speed fiber optic backbones to link distributed control systems across noise-intensive industrial environments. Unlike copper wiring, optical fibers transmit data via light pulses, making them completely immune to electromagnetic interference (EMI). Field engineers must master optical cable joining and fusion splicing techniques to guarantee low-loss data transmission across critical Programmable Logic Controller (PLC) and Distributed Control System (DCS) nodes.
