Product details

Marine and industrial compliance – what the approvals mean

The 6ES7214-1BG31-0XB0 CPU carries cULus, CE, FM, UL, and CSA approvals, so it passes the certification gate for most marine and heavy industrial panels without additional component-level paperwork. The wide ambient range of -40 °C to 70 °C survives engine-room heat or unheated deck enclosures, and the 24 V DC supply tolerates 20.4 V to 28.8 V – a realistic band for shipboard or long-cable drops.

Frequently asked questions

What replaces the 6ES7214-1BG31-0XB0?

Siemens lists the 6ES7214-1BG40-0XB0 as the successor. The -1BG40 uses firmware V4.0 and is mechanically interchangeable. Before swapping, confirm program compatibility in TIA Portal – older code may port directly, but any V4.0-specific blocks will require retargeting.

Which compliance documents come with this CPU?

The unit is certified with cULus, CE, FM, UL, and CSA marks. RoHS and REACH declarations are standard with Siemens industrial products; request them from your Siemens sales channel or our RFQ desk.
