Littelfuse TMM175 DIN-Rail Time-Delay Relays
Littelfuse TMM175 DIN-Rail Time-Delay Relays are multi-function timers that offer high precision and accuracy. These relays combine multiple timing modes and universal voltage in a slim 17.5mm housing and provide 10 timing modes ranging from 0.1s to 100h, covering most standard automation tasks. The various modes include signal on delay, cyclic on/off, cyclic off/on, signal off delay, signal off/on, leading edge impulse, and leading edge bi-stable. The TMM175 is an asymmetric on-off/off-on timer, allowing the "on" duration to be equal to or unequal to the "off" duration, making it suitable for applications requiring different time intervals. Littelfuse TMM175 DIN-Rail Time-Delay Relays are ideal for use in food and beverage, building automation, HVAC, packaging, and industrial panel applications.Features
