The 849 timing relays manufactured by Allen Bradley are AC-powered pneumatic relays. These relays support on-delay and off-delay arrangements. The on-delay arrangement provides a time delay after the 849 timing relay's coil is energized, and the off-delay arrangement provides a time delay after the coil is de-energized. The 849 timing relays are available with timing ranges from 1/20 second to 180 seconds and operating temperature ranges between 0 and 104 degrees Fahrenheit. These timers must be installed vertically with their solenoid mechanisms at the top and their timing units at the bottom.
