The 388 timers are square base, bladed versions of time delay relays. On delay, off delay and
interval functions are all available with either AC or DC inputs. On delay and interval products can
have up to three poles. Off delays have two poles. The timing circuit is oscillator based. Fixed time
and externally adjustable versions. Both socket and flange mount versions are available.
