Product Details
BF-D204T is a dual-channel (4–8 period) time controller with DIN-rail mounting and two normally open contact outputs. Each channel supports four on/off periods per day; combining both channels into one output provides eight on/off periods per day.
Displays the current time with a timekeeping error of less than 1 second/day and maintains timekeeping for up to 72 hours after a power outage.
BF-204T uses an advanced power-supply design to ensure stable, reliable, and continuous operation as the supply varies between AC80～240V.
