Schneider Electric 821TD10H-UNI

The time delay relay in the SE Relays 820 series is designed for versatile timing applications, offering 10 distinct timing functions and an extensive timing range spanning from 100 ms to 10 days. This relay operates with a universal voltage input of 12 to 240 VAC/VDC, with a contact rating of 15A, suitable for various operational needs including 1/2hp at 120VAC and 1hp at 240VAC.

Configured with silver alloy contacts in an SPDT arrangement, this relay is housed in a slim 17.5 mm modular package, ideal for installations in limited spaces. The relay supports 35-mm DIN rail mounting, simplifying the installation process. Status indicators are integrated into the design, featuring a green LED for input indication and a red LED that blinks during timing or remains steady when energized, providing clear operational feedback.

Complying with the European Restriction of Hazardous Substances (RoHS) directive, this relay is constructed with environmental considerations in mind. Notably, it is designed to operate efficiently in ambient temperatures ranging from -20°C to 55°C, and is rated for mechanical durability of up to 30 million cycles. The Designation Code for this product ensures compatibility with industry standards and reliable performance in diverse applications.
