Product Introduction
The MTL 8707-CA-08 is an 8-module carrier backplane engineered for the PAC8000 and MTL 8000 remote I/O and process automation platforms. It serves as the physical and electrical backbone for distributed control architecture, supporting up to eight individual I/O modules alongside interface or node service cards (such as Profibus or Modbus communication gateways).
The carrier distributes internal bus power, address lines, and data signals reliably across all populated slots, ensuring a clean, organized, and structurally sound layout inside heavy industrial control enclosures.

Compliance & Standards Alignment
- Designed and manufactured in accordance with rigorous industrial EMC and electrical safety frameworks for modular process control hardware.
- Constructed to provide robust mechanical and noise-immune grounding paths when paired with appropriate cabinet earth rails.
Technical Note: Always inspect backplane connector pins and structural guide rails for particulate debris or bending prior to mounting I/O modules onto the 8707-CA-08 carrier.
Storage & Asset Preservation Guidelines
- Keep the carrier backplane protected inside moisture-barrier or anti-static packaging to guard connector pins against environmental oxidation.
- Store units in a climate-controlled warehouse environment where relative humidity is maintained strictly below 60%.
- Avoid mechanical stacking or heavy pressure on the carrier assembly to prevent distortion of the backplane frame.
Physical Installation Prerequisites
- Ensure that all power feeds, network communication lines, and field loops running to the sub-rack are completely de-energized and locked out (LOTO) prior to installation.
- Secure the 8707-CA-08 carrier firmly to the cabinet backplate or DIN structure using all specified mounting points to maintain structural ground continuity.
- Connect the integrated earth bar directly to the clean instrument ground network to preserve system noise immunity.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this module carrier?
A: Industrial control system backplanes, racks, and parts typically classify under HS code 8538.90 (parts suitable for use solely or principally with control apparatus). Confirm final categorization parameters with your licensed customs broker.
Q: Does the carrier include communication gateway modules pre-installed?
A: Typically, the 8707-CA-08 is supplied as the base 8-slot carrier assembly. Communication interface modules (BIM/node services) and individual I/O cards are generally provisioned separately according to your project’s Bill of Materials (BOM).
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market conditions and available surplus inventory levels; contact our technical sales desk for a formal, time-sensitive quotation.
