Timer relays

Hello
Does anyone recognise these bad boys? Basically I want to know of an equivalent replacement or an understandng of the abbreviations please.

C is a common terminal to a single pole double throw timed switch, NO is the normally open contact of the switch, and NC is the normally closed contact of the switch - this is known as a Form C arrangement. There are two of these timed Form C switches in the relay. There is no indication of how to set the timing values, or whether it is an on-delay or off-delay timer, however. L and N are the line and neutral connections from an AC power source; there is no indication of what AC voltage is required.

Thanks for that explanation xnuke. I'm getting there now. But, probably because I'm new to this forum, I only uploaded one of the photo's instead of the three I intended! Here is the Main problem though. Thanks to xnuke I know what most of the symbols mean but I'm still stuck on what "IL" "RDA" & "IDL" mean and what they do?
Does anyone knows of an equivalent relay/timer, maybe from a different manufacturer?
