The Siemens 6ES7288-3AT04-0AA0 is an EM AT04 thermocouple module for the SIMATIC S7-200 SMART, with four channels and built-in cold junction compensation.
Thermocouples are what most industrial heating runs on, and this module takes them directly: pick the type in software, wire the compensating cable to the terminals and the CPU reads temperature in tenths of a degree. It is the standard choice for plastic injection and extrusion machines, furnaces, ovens and boilers.
EM expansion modules clip onto the right-hand side of an S7-200 SMART SR, ST or G2 CPU and are recognised automatically – the module takes the next free address range and needs no switches or jumpers. Up to six EM modules can be added to one CPU, in any mix of digital and analog, so a machine that outgrows its controller can be extended without replacing it. The economic CR-series CPUs do not accept expansion modules.

Frequently asked questions
Which CPUs does this module work with?
All expandable S7-200 SMART CPUs: SR20, ST20, SR30, ST30, SR40, ST40, SR60, ST60, the V3.0 versions and the S7-200 SMART G2 CPUs. It does not work with the economic CR-series CPUs, which are not expandable, and it is not compatible with S7-1200 or the older S7-200.
Do I need to configure anything after fitting it?
No hardware settings. Add the module to the hardware configuration in STEP 7-Micro/WIN SMART in the same slot order as it sits on the rail, download, and the addresses are assigned automatically.
How many of these can I install on one CPU?
Up to six expansion modules in total per CPU, counting all EM types together.
Is this a genuine Siemens module?
Yes. RendatSP supplies new original Siemens parts only, with the Siemens order number and packaging.
