The Honeywell 51305508-100, also known as the XLCNE2, is a specialized Local Control Network (LCN) extender paddle board designed for use within Honeywell TDC 3000 distributed control systems. This module functions as a fiber-optic interface to extend the LCN communication backbone, facilitating reliable, high-speed data exchange between controllers, I/O subsystems, and operator interfaces across extended distances.
| Model | 51305508-100 (XLCNE2) |
| Manufacturer | Honeywell |
| Power Requirement | 5 VDC |
| Current Draw | <= 500 mA |
| Isolation Voltage | 1500 V |
| Operating Temperature | 0 degC to +60 degC |
| Connector Type | ST-style fiber-optic |
It acts as a network interface to extend the LCN communication backbone over fiber-optic links, allowing for greater physical separation between control nodes than is possible with standard copper cabling.
A standard redundant LCN extension typically requires four XLCNE2 boards: one for each A and B redundant fiber link at both ends of the network segment.
No, the 51305508-100 is a replacement for the older LCNE and LCNE2 series but is not backward compatible with them. System-wide upgrades are generally required when transitioning to this model.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
