Data sheet Electronic timer CT-MFD.12 Multifunctional with 1 c/o (SPDT) contact The CT-MFD.12 is a multifunctional electronic time relay. It is from the CT-D range. 2CDC 251 089 F0006 With their MDRC profile and a width of only 17.5 mm, the CT-D range timers are ideally suited for installation in distribution panels as well as for industrial applications where compact dimensions are required. Characteristics –– Rated control supply voltage 24‑48 V DC, 24‑240 V AC –– 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 –– Control input: voltage‑related triggering, polarized, capable of switching a parallel load –– Light‑grey enclosure in RAL 7035 –– 1 c/o (SPDT) contact (250 V / 6 A) –– Width of only 17.5 mm (0.689 in) –– 2 LEDs for the indication of operational states Approvals A UL 508, CAN/CSA C22.2 No.14 EAC R E CCC L RMRS Marks a CE b RCM Order data Type Rated control supply voltage Time range Output Order code CT-MFD.12 24‑48 V DC, 24‑240 V AC 0.05 s ‑ 100 h 1 c/o (SPDT) contact 1SVR 500 020 R0000 Functions Operating controls 1 Rotary switch for the preselection of the time range 2 Potentiometer with direct reading scale for the fine adjustment of the time delay 3 Rotary switch for the selection of the timing function 4 Indication of operational states U: green LED V control supply voltage applied W timing R: yellow LED V output relay energized 5 5 Circuit diagram 2CDC 251 089 F0006 1 4 2 3 Application With their structural form and their width of only 17.5 mm, the CT‑D range timers are ideally suited for installation in distribution panels. 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. This reduces inventory and saves money. Operating mode The CT‑MFD.12 has 1 c/o (SPDT) contact and provides 7 timing functions. The function is rotary switch selectable on the front of the unit. Each function is indicated by an international function symbol. One of 7 time delay ranges, from 0.05 s to 100 h, can be selected with another rotary switch. The fine adjustment of the time delay is made via an internal potentiometer, with a direct reading scale, on the front of the unit. 2 - Electronic timer CT-MFD.12 | Data sheet Function descriptions / diagrams A ON‑delay This function requires continuous control supply voltage for timing. Timing begins when control supply voltage is applied. The green LED flashes during timing. When the selected time delay is complete, the output relay energizes and the flashing green LED turns steady. If control supply voltage is interrupted, the output relay de‑energizes and the time delay is reset. Control input A1‑Y1/B1 is disabled when this function is selected.
