Pulse Counter 3-Channel Ethernet + Wi-Fi LIW-03 ETH Zamel SUPLA

The LIW-03 ETH pulse counter by Zamel is a modern, modular device designed for precise monitoring of electricity, water and gas consumption in the SUPLA smart home ecosystem. Equipped with three independent pulse inputs, it allows direct counting of pulses from standard meter outputs (e.g. SO/OC outputs) or dedicated pulse overlays, allowing easy integration of traditional media counters into the building automation system.

Dual connectivity: Wired Ethernet and Wi-Fi

The device is distinguished by the presence of the Ethernet (RJ-45) interface, which guarantees maximum connection stability and resistance to interference inside metal electrical switchgears. In addition, the built-in Wi-Fi 2.4 GHz module provides full flexibility of installation where it is difficult to supply the network cable.

All measurement data is continuously archived in the SUPLA Cloud. From the free mobile application, the user gains access to clear consumption charts in minute, hour, daily, monthly and annual terms and the function of converting consumption into real costs.

Key features and benefits of the LIW-03 ETH counter

• 3 independent measuring channels: Simultaneous monitoring of up to three different media (e.g. electricity, water, gas) with one module.
• Double communication: Stable IEEE 802.3 10/100 Mbps Ethernet wired port and 802.11 b/g/n Wi-Fi wireless connectivity.
• Precise analysis and history: Clear consumption charts, period comparisons and cost calculations in the SUPLA application.
• Wide compatibility: Cooperation with the SO output standard (according to EN 62053-31) and potential-free OC outputs.
• Universal power supply: Safe supply voltage 12 to 24 V DC.
• Standard modular housing: Width of 2 modules (35 mm) for quick mounting on DIN rail TH-35.
• Working status indication: LEDs indicating power status, connection status and configuration mode.

Frequently Asked Questions (FAQ)

Can the LIW-03 ETH meter only work over a network cable without turning on Wi-Fi?

Yes, the built-in RJ-45 Ethernet socket allows for a stable wired connection to the local network and the Internet, which is especially recommended when installed in metal distribution cabinets.

What devices and meters can be connected to impulse inputs?

Any electricity meters, water meters or gas meters equipped with a standard SO pulse output (according to EN 62053-31), OC output or appropriate pulse overlays can be connected to the inputs.

What power supply is required to start the device?

The meter requires DC power supply in the voltage range 12 ÷ 24 V DC (e.g. from modular power supply to DIN rail).
