The 388 timers are square base, bladed versions of time delay relays. On delay, offdelay and interval functions are all available with either AC or DC inputs. On delay and interva 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. **==> picture [506 x 552] intentionally omitted <==** **----- Start of picture text -----**
