6ES7215-1HG40-0XB0

Product information

The 6ES7215-1HG40-0XB0 is a Siemens SIMATIC S7-1200 compact CPU designated CPU 1215C DC/DC/Relay. It is the highest-integration standard CPU of the first S7-1200 generation: 200 KB of work memory, 14 digital inputs, 10 relay outputs rated 2 A, 2 analog inputs at 0–10 V DC and — unlike the CPU 1214C — 2 analog outputs at 0–20 mA, all on a 24 V DC supply with two PROFINET ports.

The two integrated analog outputs are usually the deciding factor between this CPU and the CPU 1214C: they allow an analog actuator, valve or drive reference to be driven without adding an analog output module. The 1215C also carries more work memory than the 1214C, which matters where program size is close to the limit.

Choosing between the CPU 1215C variants

The CPU 1215C is supplied in several configurations and the ordering code identifies which one you have:

• …1HG40… — DC/DC/Relay, 24 V DC supply with relay outputs. The variant described on this page.
• …1AG40… — DC/DC/DC, 24 V DC supply with solid-state outputs, for fast switching.
• …1BG40… — AC/DC/Relay, mains supply with relay outputs.

When replacing an existing unit, match the complete ordering code on the installed CPU rather than the family designation alone — the output stage differs between these variants.

Typical applications

• Machines needing analog actuation as well as digital I/O, without an additional analog output module
• Control tasks where program size is beyond what the CPU 1214C work memory allows
• Packaging, process and material handling equipment with mixed relay and analog circuits
• Line-topology installations using the two PROFINET ports to daisy-chain devices without an external switch

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

Frequently asked questions

Does the CPU 1215C have analog outputs?
Yes — two integrated analog outputs at 0–20 mA DC, in addition to two analog inputs at 0–10 V DC. The CPU 1214C has analog inputs only.

How much work memory does this CPU have?
Siemens lists 200 kbyte of integrated work memory for this article number, together with 4 MB of load memory.

What is the difference between 1HG40 and 1AG40?
The output stage. 1HG40 uses relay outputs rated 2 A; 1AG40 uses solid-state DC outputs for faster switching.

How many modules can I add?
Up to 8 signal modules, 3 communication modules and 1 signal board — the maximum local expansion of the S7-1200 family.

Do the two PROFINET ports need an external switch?
No. Both ports are on an integrated switch, allowing devices to be daisy-chained in line topology.

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