Zelio Time - Timing Relays
RE7, RE8, RE9
A timing relay is a component which is designed to time events in industrial automation systems by closing or opening contacts before, during or after a set timing period.
There are two main 'families' of timing relays:
- "DIN rail mounted" relays (RE7, RE8, RE9, RE17, REXL…) designed for mounting on DIN rails in an enclosure,
- "Panel mounted" relays type RE48A designed for mounting on the front of a panel to give users easy access to the settings.
These relays have one, two or four outputs. Sometimes the second output can be either timed or instantaneous.If the power is switched off during the timing period, the relay reverts to its initial position.
