Description

Feature	Detail
Product	Gossen Metrawatt Z301A — ECS-LAN Booster / Router
Purpose	Extends and optimizes ECS-LAN data-bus communication in energy/measurement networks — ideal for large installations with meters/sensors spread out over distance. (arc.ro)
Functionality	- Allows star or extended ECS-LAN topologies: takes 2-wire input and provides 4-wire outputs (with booster) to feed multiple segments. (arc.ro) - Built-in booster increases transmission distance — much larger than standard RS-485 / basic bus, enabling stable data transfer over long cable runs. (arc.ro)
Bus / Network Compatibility	Works with ECS-LAN (the proprietary/legacy LAN/bus network used by Gossen Metrawatt summators/meters) — particularly useful when connecting summators/meters over long distances or complex panel layouts. (gossenmetrawatt.de)
Configurable Settings	Baud rate can be set via internal DIL switches (62.5, 125, 375 kBaud — default 62.5 kBaud). Input-bus termination resistor for the 2-wire side can be switched on/off as needed. (arc.ro)
Power Supply & Physical Info	Requires DC power supply: 20 – 70 V DC. (arc.ro) Housing approx. 22.5 mm wide, suitable for DIN-rail or panel installation per standard meter-panel wiring practices. (arc.ro)
Use Cases	• Large buildings, complexes, factories or multi-meter installations where meters/summators are distributed at different locations. • Retrofitting or expanding existing energy-monitoring / building-management installations using ECS-LAN. • When wiring distance or topology (star, branching) exceeds standard bus-limits and stable communication is critical.
Advantages	- Extends ECS-LAN bus distance and overcomes limitations of long cable runs or multiple branches. - Enables flexible wiring topology (star or branched). - Configurable termination and baud-rate settings make it adaptable to many installation types. - Helps maintain stable data communication across distributed meters/sensors — important for reliable monitoring, logging, or building-management systems.
Condition / Notes	According to the product archive, Z301A is listed as “discontinued / not supplied” — (gossenmetrawatt.de). That means you may only find it from surplus stock or specialized distributors. If offering to customers, make clear it's a legacy/archived part — useful especially for maintenance, legacy-system support or retrofit jobs.
