24v 60s Timer Relay

Adjustable Delay Timer Relay Details

The selection of time relay is mainly due to the delay mode and parameter coordination. The following aspects should be considered when selecting.

(1) The choice of delay mode. The time relay has two types of power-on delay or power-off delay, which should be selected according to the requirements of the control circuit. The reset time after the action is longer than the inherent action time, so as to avoid malfunction, or even no delay. This is especially important in the occasions of repeated delay circuits and frequent operations.

(2) Type selection. For occasions that require low delay accuracy, generally cheaper electromagnetic or air damping time relays are used; conversely, for occasions that require high delay accuracy, electronic time relays can be used.

(3) Coil voltage selection. Select the voltage of the time relay to attract the coil according to the voltage of the control circuit.

(4) Selection of power supply parameter changes. In the occasions where the power supply voltage fluctuates greatly, it is better to use air damping or electric time relays than the transistor type. In the occasions where the power supply frequency fluctuates, electric time relays should not be used. When the temperature changes greatly, air should not be used. Damping time relay.
