FAQ

Questions Buyers Ask Most

What is 6ES5440-8MA22 used for?＋

6ES5440-8MA22 is a Siemens SIMATIC S5 Digital Output 440 module. Its four non-isolated 24 V DC outputs switch external loads in compatible S5 and ET 100U/200U control systems, with each output rated at 2 A.

Which systems accept 6ES5440-8MA22?＋

6ES5440-8MA22 is listed by Siemens for S5-90U, S5-95U and S5-100U programmable controllers and ET 100U/ET 200U stations. Match the installed rack and module arrangement before selecting it as a replacement.

What load ratings apply to 6ES5440-8MA22?＋

6ES5440-8MA22 has a 24 V DC rated load voltage, a permissible range of 20–30 V, and a rated output current of 2 A per channel. The four outputs together are limited to 4 A.

Are the outputs of 6ES5440-8MA22 isolated?＋

6ES5440-8MA22 has four outputs in one group without galvanic isolation. Its non-isolated output design is part of the Siemens specification, so the installed load wiring and supply arrangement must match that configuration.

How does 6ES5440-8MA22 indicate output faults?＋

6ES5440-8MA22 provides a red fault LED for a short circuit or missing L+ load voltage. Siemens also documents error diagnostics for this module; diagnostic byte handling depends on the installed S5 CPU and its version.

What happens after a short circuit on 6ES5440-8MA22?＋

6ES5440-8MA22 has short-circuit-protected outputs that switch on automatically after the short circuit no longer exists. The Siemens manual specifies this behavior for the four-channel 24 V DC/2 A module.

What should be provided when ordering 6ES5440-8MA22?＋

6ES5440-8MA22 should be identified by its complete Siemens article number, the installed S5 or ET station, required quantity, and 24 V DC load details. Siemens lists this article as discontinued without a direct replacement.
