Does all the X80 modules compliant with ISA 71.4 or apply only to modules with the "H" and "C" suffixes?

How can we help you today?

ISA S71.04 complies only to Conformal coated or hardened hardware.

ISA S71.04 comply for the treatment of more severe environments.

If the Modicon X80 automation platform has to be used in more severe environments or is required to start and operate in an extended temperature range, from -25 °C to +70 °C/-13 °F to +158 °F, the “ruggedized” offer features industrially hardened processor modules, X-bus and X-bus + Ethernet racks, rack expansion modules, and communication modules that have a protective coating on their circuit boards
Hope this would help to solve the query. Feel free for any further assistance.
