Timer Control for Triac and Relay
Description
The timer control circuit, U2100B, uses bipolar technology. It has different mode selections (Zero voltage switch, Phase control, Relay control). The output stage is triggered according to input conditions. It can be used in triac application for two or three wire system as a power switch.
Features
D Adjustable and retriggerable tracking time D Window monitoring for sensor input D Enable input for triggering D Internal noise suppression (40 ms) and retrigger
blocking (640 ms)
Applications
D Motion detectors D Touch sensors D Timer
D Two or three wire application
