6ES7214-1BH50-0XB0

Product information

The 6ES7214-1BH50-0XB0 is a Siemens SIMATIC S7-1200 G2 compact CPU designated CPU 1214C AC/DC/RLY. It combines a mains supply input of 85–264 V AC with 14 digital inputs at 24 V DC, 10 relay outputs rated 2 A and 250 KB of program memory with 750 KB of data memory.

This is the G2 counterpart to the widely installed AC/DC/relay CPU 1214C, and it is the variant to specify where the controller is fed from mains and the output circuits switch AC or mixed loads. Compared with the first-generation CPU of the same designation, program memory increases from 150 KB to 250 KB, bit-operation time falls from 0.08 µs to 37 ns, load memory rises to 8 MB, and the retentive area grows from 14 KB to 20 KB.

Platform notes for G2

S7-1200 G2 is a new hardware generation requiring STEP 7 V21 or higher; it is not a firmware upgrade of the earlier S7-1200. Migration from a first-generation project should be planned with device definition, library and motion configuration checks. Siemens lists this article number as an active product.

Typical applications

• Machine panels supplied directly from mains, avoiding a separate 24 V DC supply for the controller
• Output circuits that switch AC loads, or a mix of AC and DC loads from the same CPU
• New equipment specified on the current S7-1200 generation rather than the phase-out-announced first generation
• Applications needing more program and data memory than the previous 150 KB work memory allowed

Application examples describe typical uses of this product type. Suitability for your own installation must be confirmed against your engineering documentation.

Frequently asked questions

What supply voltage does this CPU accept?
85–264 V AC at 47–63 Hz, so it can be connected to common single-phase mains supplies without an external DC power supply for the controller.

What is the difference from the previous AC/DC/relay CPU 1214C?
Memory, speed and load memory all increase: 250 KB program and 750 KB data against 150 KB work memory, 37 ns against 0.08 µs bit operations, and 8 MB against 4 MB load memory.

Do I need STEP 7 V21?
Yes, Siemens lists STEP 7 V21 or higher for this G2 article number.

Can relay outputs switch inductive AC loads directly?
The contacts are rated 2 A. Contact life and suppression requirements depend on the load type and switching frequency, so verify against your application.

Where is this CPU manufactured?
Siemens product data lists China as the country of origin for this article number. Confirm against the nameplate of the actual unit.

What is the price and lead time?
Confirmed individually against current availability for the specific revision and quantity.
