Product Details
The ABB LD 810HSE EX, also cataloged as the LD 810HSE EX Communication Module, operates as a dedicated hardware component for fieldbus network linking and data conversion within ABB S900 IO hardware platforms. Mounted on a standard DIN rail, the module links four H1 field networks with a High Speed Ethernet (HSE) trunk, executing high-speed protocol conversion across Foundation Fieldbus architectures.

Backplane Bus Communication Velocity & I/O Density Scaling
The LD 810HSE EX linking device maintains backplane bus communication velocity across deterministic Ethernet and Foundation Fieldbus segments. By aggregating four separate H1 links into a single High Speed Ethernet port, the module optimizes cabinet I/O density scaling while isolating field communication signals. High-density firmware flash compatibility ensures synchronized parameter exchange across connected controller sub-racks without introducing network transmission bottlenecks.
Frequently Asked Questions
Q: Can the LD 810HSE EX be installed to replace a single LD 800 device in an existing redundant pair?
A: No. Mixing LD 800 and LD 810HSE EX modules in a single redundant pair is not supported; both units in a redundant pair must be replaced with LD 810HSE EX modules simultaneously.
Q: How is primary operating power delivered to the LD 810HSE EX module and its H1 links?
A: The module itself requires an external 24 VDC power supply connection, while all connected H1 fieldbus links must be powered independently via dedicated fieldbus power conditioners.
Q: How is the redundancy link cable provided for paired LD 810HSE EX installations?
A: The redundancy cable can be procured or fabricated directly by the customer according to standard Ethernet link specifications rather than requiring a proprietary factory cable.
Field Installation Guidelines
Follow these technical procedures during panel installation and field cabling:
- DIN-Rail Mounting: Snap the LD 810HSE EX securely onto a top-hat 35 mm DIN rail, verifying that the rear metal DIN clamp fully latches onto the rail edge.
- Earth Ground Bonding: Ensure the DIN rail surface is unpainted and directly bonded to the cabinet protective earth (PE) bus to establish shield termination ground paths for the HSE and H1 ports.
- Power Connection: Wire an isolated external 24 VDC power source to the module power terminals; confirm separate power supplies are configured for the H1 fieldbus segment conditioners.
- Network Cabling: Connect the HSE network cable to the primary Ethernet port and route shielded twisted-pair cables from the four H1 links, ensuring line termination resistors are active at both ends of each H1 segment.
