Reliable Multifunction Timing Control for Industrial Automation
The Finder 93.21.0.024 multifunction timer socket provides adjustable time-dependent switching for industrial electrical control systems. By combining an electronic timer with a compatible plug-in relay, the device allows connected equipment to be activated or deactivated according to a selected timing function and delay setting.
The AI on-delay function delays relay activation after the control supply is applied. The DI interval function activates the relay immediately and switches it off after the selected interval. The GI delayed pulse function produces a timed output pulse after a delay, while the SW symmetrical flasher function repeatedly switches the relay on and off, beginning with the output energised.
Timing functions and ranges are selected using the integrated DIP switches, while the required delay is adjusted using the rotary trimmer. The LED indicator provides visual feedback on the operating state, helping engineers identify whether the unit is unpowered, timing or operating with its relay output energised.
The Finder 93.21.0.024 supports both 12 V and 24 V AC/DC applications, but the installed relay must match the actual supply voltage. A compatible 12 V relay is required for 12 V operation, while a compatible 24 V relay is required for 24 V operation. The supply range does not mean that a single installed relay can automatically operate across both voltages.
For electromechanical switching, the socket can be combined with a Finder 34.51 relay providing a 6 A changeover contact. Alternatively, compatible Finder 34.81 solid-state relays provide electronic switching for suitable AC or DC loads. This modular arrangement gives control panel designers flexibility when selecting relay technology for different industrial applications.
