Power consumption measurement JA-150EM-DIN

JA-150EM-DIN — wireless module for electric meter pulse output

The JA-150EM-DIN from Jablotron is a DIN-rail mounted module that converts a standard impulse (S0) output of an electricity meter into wireless data forwarded via the control panel to the MyJABLOTRON web service. It provides informative meter readings, supports two tariff states and includes an independent input for monitoring events such as a switchboard cover opening.

The unit is mains powered: 230 V / 50 Hz, with typical consumption of approx. 0.5 W and a maximum of 1.2 W (max current 10 mA). The IN and PU inputs are low-voltage and galvanically isolated from mains (operating voltage 5 V, maximum external overvoltage 30 V DC, max cable length 3 m). The PU input is compatible with S0 impulse outputs class B according to EN 62053-31; the TA input accepts remote tariffing signals up to 230 V AC.

Wireless communication operates at 868.1 MHz using the Jablotron protocol via a TRX-30 radio module. The module includes an internal antenna and allows connection of an external AN-868 antenna if needed.
