Four independent continuous control loops for documented SIMATIC S7-300 temperature-control applications.
Siemens identifies the complete order number 6ES7355-2CH00-0AE0 as the FM 355-2 C temperature controller module with four channels. The C version is the continuous-action controller with analog outputs; the separately ordered S version uses step and pulse digital outputs.
The module is intended for closed-loop temperature control in SIMATIC S7-300 systems. Exact suffix, sensor type, signal ranges, front connectors and original STEP 7 project must be checked before replacement.

| Obsolescence planning | Provides the installed reference needed to plan validated migration or strategic spares. |
Siemens identifies 6ES7355-2CH00-0AE0 as PM300: Active Product and records product phase-out since 01.10.2023. Use this wording as a lifecycle reference; it does not establish interchangeability with any other FM 355-2 order number.
It is the FM 355-2 C four-channel continuous temperature controller module for SIMATIC S7-300.
Siemens specifies four closed-loop controllers.
The official data covers thermocouples B, E, J, K, R and S plus Pt100 resistance thermometers.
No. The S version uses step and pulse digital outputs, while this C version has analog outputs.
