ELM264x - Introduction
Fig.2: ELM2642-0000, ELM2644-00002 and 4-channel multiplexer, 1 x 4 reed relay 48 V AC/DC, 0.5 A, potential-free make contact
The ELM2642 and ELM2644 are equipped with reed relays as switching elements that allow fast switching cycles with a long service life. The absolute electrical isolation and the constant contact resistance of the reed switch allow the measurement even of sensitive signals up to fast scanning operation.
