GEYA GRT8-A1 230 V Timer Relay

Product detailed description

The single-function time relay GEYA GRT8-A1 is a reliable and compact solution for automating switching processes in domestic and industrial switchboards. The model marked "A1" operates in the delayed ON mode (Delay ON). After connecting the supply voltage, the relay starts counting the set time and switches on the output contact after its expiration.

Setting the time is simple and accurate thanks to two rotary potentiometers on the front panel. The first selector allows you to choose one of 10 time ranges (from 0.1 s to 10 days). The second selector then finely adjusts the specific value within the range of 10 % to 100 % of the selected range. Status LED diodes clearly indicate the presence of power supply (green LED) and the state of the output relay (red LED).

Main advantages and applications

• Delayed ON (Delay ON): the load is switched on only after the set time has elapsed from the moment the voltage is connected.
• Wide time range: setting from 0.1 s to 10 days in 10 ranges, including permanent ON or OFF.
• Compact width of 18 mm: occupies only 1 module on a DIN rail (TH35).
• Clear LED indication: green LED for power supply, red LED for output status.
• High switching capacity: output switching relay 16 A / 250 V AC (1x SPDT).
• Broad application: delayed starting of motors, run-down of pumps and fans, gradual switching on of loads to limit current surges.
