Product details

The Siemens 6ES7171-1XX00-6AA0 is a SIPLUS HCS724I network voltage compensation module NE724 designed for central connection ZA724I. It measures voltage only (no current measurement), with a relative accuracy of 3 %, and communicates over the system interface. Power is supplied via the central connection using 4 connecting cables with ring cable lugs; voltage measurement inputs also use M6 ring cable lugs.

Operating conditions

Atmospheric pressure 860–1 080 hPa (operation) / 660–1 080 hPa (storage); altitude 2 000 m; mount vertical; forced ventilation; overvoltage category III; pollution degree 2; IP20.

Frequently asked questions

What is the maximum operating temperature for this module?

Maximum 55 °C. Minimum 0 °C.

Can this module be used in a panel near a steam press?

It is rated IP20 and overvoltage category III with pollution degree 2 – fine inside a clean, dry enclosure. Keep it out of direct steam, as IP20 offers no moisture ingress protection.
