Programmable Timer
The Model 300 Programmable Timer provides precise control for diverse industrial applications. Its configurable voltage options, 10-28V AC/DC or 40-260V AC/DC, ensure broad compatibility across different power systems. Users can select timing ranges from 0.15 seconds to 64 minutes, offering significant flexibility for various operational sequences and process requirements. With a repeatability of 0.1% and an accuracy of ±5%, consistent performance is maintained across repeated cycles. The SPDT contacts are rated for 10A at 240VAC resistive, accommodating significant electrical loads. Operational reliability is further supported by a wide temperature range of -20° to +140° F and a mechanical relay life of 10 million operations. This timer is designed for dependable service in demanding industrial environments, backed by a 5-year unconditional warranty. UL Recognized and CSA Certified, it meets critical industry standards for safety and performance.
