The A1M-0999M-465 is a microprocessor-controlled, delay-on-make time delay relay from the A1M Series. It operates on a 240 VAC, 50/60 Hz input and features five user-selectable time ranges, adjustable from 50 milliseconds to 999 minutes via a 3-digit push-button switch. This relay provides high precision with ±0.1% repeatability and includes a DPDT output rated for 10 A at 240 VAC. It is equipped with transient voltage protection, a timing indicator light, and is housed in a flame-retardant polycarbonate case with an 8-pin plug termination. Its easy programmability and high accuracy make it suitable for a wide range of industrial control applications where precise timing is required after power is applied.
