Altronix PACE1KLDC 10Base-T1L to Ethernet Media Converter

Overview

The Altronix PACE1KLDC is a compact single-pair Ethernet (SPE) adapter that bridges 10Base-T1L (IEEE 802.3cg) devices to standard 10BaseT RJ45 networks over a single run of 2-wire twisted pair — reaching up to 1km (3,280 ft.) on infrastructure that would have required costly cable upgrades or intermediate switches under conventional Ethernet. If you're deploying IP sensors, cameras, or IoT endpoints across wide-area industrial or building automation environments where pulling Cat5/6 to every node isn't practical, the PACE1KLDC is the connection layer that makes those runs viable.

The device draws a measured 0.6W — 55mA at 12V or 30mA at 24V — and accepts either 12/24VDC or 12/24VAC input, making it compatible with the low-voltage power infrastructure already present on most security and automation panels. It holds UL/cUL and CE listings under UL 62368-1, which matters for installations requiring code-compliant low-voltage electronics.

Key Features

• 1km SPE reach over 2-wire: Standard 802.3cg 10Base-T1L operates at up to 1,000 meters on a single twisted pair — versus the 100m hard ceiling of conventional Ethernet. For campus perimeters, parking structures, or warehouse floor coverage, this eliminates the need for intermediate switches or fiber runs at every distance break.
• 10Mbps SPE data rate: 10Mbps is sufficient for most IP sensor and low-frame-rate camera traffic. If you're running continuous 4K video streams or high-density NVR backhaul, plan the SPE segment for endpoint-to-aggregation, not trunk. But for the vast majority of edge device connections, 10Mbps clears the bar comfortably.
• Standard RJ45 Ethernet output: The local-side port presents as a conventional 10BaseT RJ45 interface — your switch, NVR, or edge server sees a standard Ethernet connection, with no proprietary drivers or configuration required on the network side.
• Ultra-low 0.6W power consumption: At 55mA draw on 12V or 30mA on 24V, the PACE1KLDC adds negligible load to an existing power supply. A standard 1A auxiliary output can comfortably power 15+ units, which matters when you're populating a large sensor field from a single panel.
• Dual-voltage AC/DC input: Accepts 12 or 24V in either AC or DC form — a practical advantage when the nearest panel output is an untransformed AC tap from a legacy transformer rather than a regulated DC rail. No additional power conversion hardware needed.
• –40°C to 75°C operating range: This temperature window covers unheated utility spaces, rooftop enclosures, and outdoor junction boxes in northern climates. The PACE1KLDC won't need a thermostat-controlled enclosure heater in most North American installations.
