T5, Digital Timer – AC PowerFeatures wtih all optional accessories:Waterproof, corrosion-proof This industrial timer was built for the plating industry to take acid fumes, caustic chemicals, washdown. IP65 enclosure makes this suitable for wet, production floors, industry, or outdoors.Backlit display.The loudest buzzer on a timer we know of.Relay controls other devices up to 15 A using a piggyback cord.Choice of N.O or N.C. relay output.Waterproof – meant for tough industrial environments.Loud 103dB warbling tone cuts through the loudest industrial noise.Rugged. Built for rough, wet and corrosive environments.Simple. Easy to use like a kitchen timer.Compact enclosure measures only 5 x 5 inches.High current capacity. 15 A relay output.Many operating modes to choose from.If you need it, its probably built-in.Many options to add instant automation to your process.Digital Process Timer is easy to program with only three pushbuttons. Counts down the cycle you set and then resets to the same time for the next cycle. When the cycle is completed, a very loud 103dB warbling buzzer sounds and the red beacon LED flashes. Relay output will control devices using the convenient piggyback cord. OperationSimply press the front green button to start and stop the time. The blue buttons adjust the time up or down. Once the countdown time reaches zero, the time then counts the overrun so you know how long the timer has been alarming.Many different operating modes are selectable with switches inside the box.Mode 1(default) counts down from the set time. Cycle can be cancelled by holding the start button. If time is set to zero then it counts up.Mode 2 like mode 1 but does not allow cancellation.Mode 3 is for triggering the time cycle mechanically with a contact close (like a proximity switch) that remains closed throughout the countdown.Mode 4 allows pausing and re-starting the cycle until the time accumulates to set value.Mode 5 stops automatically at the end of cycle.Mode 6 provides an early warning on the beacon LED.Mode 7 is a guard duty that requires the start button to pressed continually or else an alarm sounds (cycle repeats indefinitely).Mode 8 is especially for spray rinses in plating operations.Mode 9 is an machine run-time countdown.Mode 10 is an on-delay.Mode 11 is a repeat cycle.Mode 12 is an off-delay for the relay.In addition you can select between MM:SS for up to 100 minutes, or HH:MM for up to 100 hours See "operating modes" chart below for detail on the exact behavior of the modes.
