GEYA GRT8-A1 230V time relay

The GEYA GRT8-A1 single-function time relay offers a reliable and compact solution for automating switching processes in domestic and industrial switchboards. The model designated with the suffix ‘A1’ provides a delayed start function (Delay ON) – once the supply voltage is applied, the relay begins counting down the set time and, once this time has elapsed, closes the output contact.

Setting the required time is very simple and precise thanks to two rotary potentiometers on the front panel. Use the first selector to choose one of 10 time ranges (from 0.1 s to 10 days), and then use the second selector to fine-tune the specific value (10% to 100% of the range). The relay also features status LEDs that clearly indicate the presence of power (green LED) and the status of the output relay (red LED).

Thanks to its standardised width of 1 module (18 mm), it fits into any standard DIN rail (TH35) control cabinet. The output changeover contact (1x SPDT) can switch loads of up to 16 A (AC1).

MAIN ADVANTAGES AND APPLICATIONS Delayed ON function: The load is switched on only after a set time interval has elapsed since power was applied.
Wide time range: Settings from 0.1 s to 10 days, divided into 10 ranges (including continuous ON/OFF). Compact width of 18 mm: Occupies only 1 module on a DIN rail.
Clear LED indication: Green LED for power supply indication, red LED for output relay status. High switching capacity: Output relay 16 A / 250 V AC (1x SPDT changeover contact).
Wide range of applications: Delayed motor start-up, run-down of pumps and fans, gradual switching on of loads to prevent inrush currents. ELECTRICAL AND TECHNICAL SPECIFICATIONS
