| Model NO. | GRT8-FR Forward And Reverse Control Time Relay |
| Rated frequency | 50/60Hz |
| Series | GRT8 |
The GRT8-FR Forward And Reverse Control Time Relay specializes in automated forward-reverse cyclic control. It precisely sets forward and reverse running intervals, ideal for motors, conveyors and rotating equipment. With stable timing performance and easy parameter adjustment, it ensures smooth, safe equipment operation, enhancing efficiency in industrial automation scenarios.
You can individually set the forward, stop, and reverse times.
With a forced stop function, it can be pressed to stop forward or reverse rotation at any time.
Ultra wide delay range, 0.1 seconds – 99 days can be set.
Relay status is indicated by LED.
1-MODULE,DIN rail mounting.
