A Siemens timing relay is a control-circuit component that switches a load after a set time delay. Siemens SIRIUS timing relays, such as the 3RP25, 3RP20 and 7PV15 families, provide time-delayed switching for control, start-up and protection circuits. Thinvent does not make timing relays. Thinvent makes industrial computers, mini PCs and thin clients. If you need a computer to run timing, control or monitoring tasks alongside your control cabinet, the Thinvent products below are the closest alternatives.

Key differences
-
The Siemens SIRIUS relay performs time-delay switching in a control circuit. Thinvent products are computers and do not perform this switching function.
-
The Thinvent IPC5 is fanless, so it has no moving parts to fail in a dusty cabinet.
-
The Thinvent IPC5 and Treo give you a choice of operating systems, including Ubuntu Linux and Thinux™ Embedded Linux, alongside Windows 11 Pro.
-
The Thinvent Treo has up to 64 GB of RAM and up to 2 TB of SSD storage, and it includes a VESA mount for panel fitting.
-
The Siemens SIRIUS range has up to 27 timing functions in its 3RP25 series, a function Thinvent products do not provide.
Which one should you choose?
Choose a Siemens SIRIUS timing relay if you need to add a time-delayed switching function to a control, start-up or protection circuit. Choose a Thinvent industrial PC or mini PC if you need a computer to run software, data logging or supervisory tasks in or near your control cabinet.
