Product Description
DCF77 Radio Clock Timer UA509P with two serial RS232 interfaces and 4 programmable relay outputs (changeover contacts, 50 Watt max. load each). 8 different plans assigned to the days of the week (holidays included or not) with up to 1024 switching times can be edited by using the 4 keys and the LC-Display in the frontpanel. Alternative pulses can be programmed to the outputs instead of switching times. The UA509P generates pulses (TTL) to control slave clocks via an external slave line booster.Characteristics
