Description

Feature	Detail
Product	Gossen Metrawatt U1660 — Data Collector Module for LON / Pulse-meter inputs
Purpose	Adds up to 8 pulse-meter inputs (S0 or floating contact) and sends those meter data over a LON network — useful to connect multiple energy meters when main summator inputs are full or meters are physically distant. (arc.ro)
Inputs	8 active S0 pulse inputs (DIN 43864), or equivalent floating contacts from energy, heat or flow meters. No extra power supply needed for meter contacts. (arc.ro)
Interface / Connectivity	LON (FTT-10A, 78 kbit/s) network interface — communicates meter data (energy, instantaneous power, pulse count, input states) as standard LON network variables. (arc.ro)
Output Data / Variables	For each input: energy (Wh), instantaneous power (W), meter-pulse count; plus binary input states for floating-contact sensors. (arc.ro)
Mounting & Supply	DIN-rail mountable module (system rail), with 24 V DC supply, supply current ~ 90 to 170 mA depending on load. (arc.ro)
Use Cases	Expanding metering networks: for buildings, factories or utilities where many individual meters (electricity, heat, water/flow) need to be aggregated; when meters are remote or beyond the reach of central summator inputs; for cost-center billing, energy management, flow/heat monitoring, etc.
Advantages	– Increases total meter-count capacity of main system without needing additional universal-input summators – Pulse-input compatibility (S0/floating contacts) — works with many meter types – Uses LON protocol — good for integration into existing LON-based building/energy automation systems – Saves wiring effort especially when meters are spread out or located far from main summator.
Condition / Notes	According to manufacturer: the module (item no. U1660-V002) has been officially discontinued since December 2022. (gossenmetrawatt.de) That means available units now are likely old stock or surplus — useful for retrofits or special systems but check availability carefully.
