Single Shot Timer - TRM and TVM series

A momentary input closure triggers the timing. At the end of the timing period the output de-energizes.

TRM has a reed relay output and the input voltage is also a timed output
TVM has only the input voltage as the timed output.

Timer On Off, Cycling Timer, Repeat Cycle Timer, On/Off Timer - TNF series

The repeat cycle mode of operation turns the output ON and OFF continuously on a repeating basis.

Flasher - BLM series

Flashers or Blinkers are a special kind of repeat cycle timers. The ON and OFF portion of the cycle are equal.

BTS series

3 circuit module: a Single Shot Timer, a Flasher and a 20 second crossing bell sound.

Delay On Make

The delayed timing period starts with the momentary input contact. After the timing period expires, the output is energized or closed on.

Delay On Break or Delay Off

With a momentary input closure the output energizes or closes on first and remains energized until after the timing period which does not begin until operating voltage, control voltage, or the opening of an separate initiate switch. After the timing period expires, the output is de-energized. This mode of operation requires standby voltage during the timing period.

True Delay On Break or true delay off is identical to the delay on break operation above, but the major difference is the standby voltage is not required during the timing period.

Delay On Make and Break

This timer always requires the standby voltage be applied at all times and the timing action initiated by either a control switch, referred to as the initiate switch, or another voltage source.

Time Clock

Programmable timers for multiple events, which can occur on a daily or weekly basis. The controller is configured for the current time and day of the week, then the events are programmed.

Event Controller

At the time of the programmed event the relay outputs can be turned off or turned on. To make one of the relays turn on for 3 hours requires two events, one to energize the relay, and another to de-energize it. One event can be used to change the state of many relay outputs.
