Description

CDT6-2T Independently Adjustable Dual On-Delay Timers

CDT6-2T provides two independently set power-on delays in one 18mm-wide DIN rail timer. The two changeover outputs can switch at different times after the same supply is applied. This supports staggered load switching to reduce coincident starting demand and can replace two separate timers where their required functions match.

Each delay has a range selector and an adjustment knob. The overall timing range is 0.1s to 10 days, with ON/OFF positions. Choose the 10A or 16A contact version and the required supply; the range includes 220VAC and wide-range 12–240VAC/DC options.

Contact arrangement	2: two changeover contacts
Contact rating	10: 10A; 16: 16A
Supply	M: 220VAC; W: 12–240VAC/DC; A–Z letter combinations: custom voltage. AC frequency is 50–60Hz.

Common Complete Models

Model	Function	Output contact Ith / Ie	Supply
CDT6-2T210M	Two independently adjustable power-on delays; two changeover contacts	10A / 2.5A	220VAC, 50–60Hz
CDT6-2T216W		16A / 5A	12–240VAC/DC; 50–60Hz for AC

These two common models identify the complete contact/supply selections. The ordering guide also permits the other listed rating, supply and custom choices; use the full specified code when ordering.

Independent Output Timing

CDT6-2T timing chart with common supply Un, control S and independently delayed outputs 15-18 and 25-28 — After supply Un is applied, output 15–18 closes after t1 and output 25–28 closes after t2. The chart also shows the S input resetting both outputs and restarting their separate delays after release.

Set t1 and t2 independently to determine the two switching times. The example chart shows t2 longer than t1; select the required values for the application. Front-panel R1/R2 indications identify the two relay outputs. The technical table specifies green power and red relay-output indication.

Connection and Dimension Drawings

CDT6-2T relay connection symbols showing supply A1/A2, control S and both changeover contact groups — The middle symbol shows both 2T changeovers: 15 common, 16 NC, 18 NO and 25 common, 26 NC, 28 NO. The adjacent views illustrate the first output and supply/control connection. A1/A2 are supply terminals; S is the reset/control input shown in the timing chart.

CDT6-2T front and side outline with four adjustment knobs and 90mm by 18mm by 65mm overall dimensions — The module is 18mm wide, 90mm high and 65mm deep. Upper side-profile sections are 31mm and 19mm. The front view shows the two terminal rows and separate range/value knobs for each delay.

The selection document lists CCC with GB/T14048.5 and CE with EN60947-5-1; request certificate document numbers from CNTD as needed. Select the applicable contact duty rating for each controlled load.

The manufacturer requires specially designed equipment and written confirmation for high reliability energy systems, applications involving personal safety or major property risk, harsh or outdoor environments, fire or explosion risks, and military or aerospace use.
