The GRT8 series is a DIN rail time relay range for timing, delay and control-circuit automation. The series includes single-function and multifunction relays, star-delta timers, pulse-output timers, asymmetric cyclers, staircase timers and communication-enabled timing relays.
Main Features
- 18mm DIN rail modular format for control panels.
- Multiple timing functions across the series, including delay on, delay off, cyclic timing, pulse output and star-delta timing.
- AC/DC supply options are available by model.
- LED indication for supply and output status on many models.
- Relay output options include SPDT and dual-contact versions, depending on model.
