The TR Series Timing Relays are designed to
meet most timing requirements by offering
more flexibility in range of input voltage,
timing range and functionality. Use a rotary
switch to choose from 20 selectable time
ranges from 0.1 second to 600 hours. We
offer both a power triggered and signal
triggered model—each with expanded
operation modes. There is a green LED to
indicate when power is ON and an orange
LED when output is ON.

B: Cycle (Signal Start, OFF First)
When the start input turns on while power is on, the output
oscillates at a preset cycle (Duty Ratio 1:1), starting while the NO
contact off.
C: Cycle (Signal Start, ON First)
When the start input turns on while power is on the NO contact
goes on. The output oscillates at a preset cycle (Duty Ratio 1:1).
D: Signal ON/OFF-Delay
When the start input turns on while power is on, the NO output
contact goes on. When a preset time has elapsed while the start
input remains on, the output contact goes off. When the start input
turns off, the NO contact goes on again. When a preset time has
elapsed after the start input turned off, the NO contact goes off
E: Signal OFF-Delay
When power is turned on while the start input is on, the NO
output contact goes on. When a preset time has elapsed after
the start input turned off, the NO output contact goes off.
F: One-Shot (Signal Start)
When the start input turns on while power is on, the NO output
contact goes on. When a preset time has elapsed, the output
contact goes off.
