It is from the CT-D range. 2CDC 251 094 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 –– Single‑function timer OFF‑delay –– 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-AHD.12 24‑48 V DC, 24‑240 V AC 0.05 s ‑ 100 h 1 c/o (SPDT) contact 1SVR 500 110 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 Indication of operational states U: green LED V control supply voltage applied W timing R: yellow LED V output relay energized 4 Circuit diagram 2CDC 251 094 F0006 4 1 3 2 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. Operating mode The CT‑AHD.12 with 1 c/o (SPDT) contact and offers 7 time ranges, from 0.05 s to 100 h. The time delay range is rotary switch selectable on the front of the unit. 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-AHD.12 | Data sheet Function descriptions / diagrams B OFF‑delay with auxiliary voltage This function requires continuous control supply voltage for timing. If control input A1‑Y1/B1 is closed, the output relay energizes immediately. If control input A1‑Y1/B1 is opened, the time delay starts. The green LED flashes during timing. When the selected time delay is complete, the output relay de‑energizes and the flashing green LED turns steady. If control input A1‑Y1/B1 recloses before the time delay is complete, the time delay is reset and the output relay does not change state. Timing starts again when control input A1‑Y1/B1 re‑opens. If control supply voltage is interrupted, the output relay de‑energizes and the time delay is reset.
