The ZR 712.30 is a 2U Zeitrelais (time relay) from E. Dold & Söhne KG, designed to insert a delayed output in electrical circuits. It provides an adjustable timing range of 15 to 300 seconds, enabling precise sequencing of relays, contactors, or alarms in industrial automation. The 2U form factor indicates its mounting height in panels or rack setups, making it suitable for compact control enclosures where space is at a premium. Model ZR 712.30 identifies this timing relay within the ZR series, offering a straightforward timing function for second-scale delays as part of a broader control system.
