ABB AB CT-MFD.21

With their structural form and width of 17.5 mm only, the CT‑D range timers are ideally suited for installation in distribution cabinets. Multifunction timers are ideally suited for service and maintenance applications, because one device can replace a number of time relays with different functions, voltage and time ranges. Rated control supply voltage 12 → 240 V ac/dc. Multifunction timer with 7 timing functions: ON ‑ delay, OFF ‑ delay with auxiliary voltage, impulse ‑ ON, Impulse ‑ OFF with auxiliary voltage, flasher starting with ON, flasher starting with OFF, pulse former. 7 time ranges (0.05 s → 100 h) in one device. 2 C/O contacts (250 V / 5 A). Control input: voltage ‑ related triggering, polarised, capable of switching a parallel load. 2 LEDs for status indication. Width of only 17.5 mm. Light ‑ grey enclosure in RAL 7035 Supply Voltage = 12 - 24 V ac/dc Time Range = 0.05 s - 100 h Mode of Operation = Flash Start with OFF, Flash Start with ON, Impulse OFF with Auxiliary Voltage, Impulse ON, OFF Delay with Auxiliary Voltage, ON Delay, Pulse Former Mounting Type = DIN Rail, Snap Number of Timer Functions = Multi Function Number of Contacts = 2 Time Increment = Hours, Seconds Power Supply = External Contact Configuration = DPDT Current Maximum = 5 A
