Recently I got an ‘updated’ version of the common 555 timer relay module. This time it comes with a wider DC operating voltage of up to 30V and an onboard trigger button in addition to external ...

The 859 Series DIN-rail timer relay module offers on-/off-delay timer modes and multiple time ranges for applications such as switch and package de-bounce sensors.

The relay contact header looks like 0.2″ (5.08mm) to me. Probably to fit screw terminal blocks. All good for low DC voltages. If you want AC switching then a SSR would be better.

WAGO Corporation's 859 Series DIN-rail Timer Relay Module offers On-/Off-Delay timer modes and multiple time ranges for diverse applications such as switch and package "de-bounce" sensors. Unlike ...

Analog circuits such as the "brute force" resistor-capacitor solution ... This forces the output high for approximately 100 ms, which is plenty of time for most relays or solenoids to latch fully.
