KNX input module EK-CA1-TP

Description
The Ekinex EK-CA1-TP is a DIN-rail input module with 8 independent analog/binary channels for interfacing potential-free contacts or passive NTC temperature sensors to a KNX bus. It enables command and status acquisition from conventional switches, push-buttons or non-communicating sensors and converts these signals into KNX telegrams. The input interrogation voltage is generated internally. The device includes an integrated KNX communication module and is powered by the KNX bus (no auxiliary supply required).
