More About this Item

One unit automatically controls lights, pumps, mixers, security systems, or any other electrical appliance in your lab or plant, without the clutter of numerous mechanical timers. Each unit can control up to four circuits.
Program each cycle length from two seconds to one year. You can selectively omit any day or days of the week and manually switch any circuit "on" or "off". A locking keyboard prevents tampering or accidental entries which may disturb critical operations.
Your programs are run according to the time set on the internal clock and feature a battery backup to protect your critical operations (order batteries separately). The battery backup also protects the system memory so in case of power failure there is no need to reprogram.

In addition to the four circuits, deluxe models also feature eight external inputs. External inputs can be used to signal the timer to start or stop a specific program. The minimum input impulse width is 250 msec. The maximum current is 500µA; maximum switch resistance is 1000Ω. Switch closure is required between input pin and common pin.
Features dry contacts for wiring to your electrical appliances; a high-impact plastic case, and a 5-ft cord with U.S. grounded plug.

      A:

      This controller allows a user to set 20 different ON/OFF programs. Each of these events includes setting an ON time, an OFF time, a cycle length (time between cycles) and omission days (days when it will not follow this program). Each of the 4 outlets can be controlled by any combination of the 20 programs.
