| Explanation: |
Product Family CDT6 - DIN rail time relay |
Series X - Digital display multifunction time relay with 20 operating modes |
Contact Arrangement 1 - One changeover contact |
Contact Current Rating 10 - 10A contacts; AC-15 operational current 2.5A at 250VAC |
Power Supply W - 12–240VAC/DC; 50–60Hz for AC |
CDT6-X combines a digital display and button settings with 20 operating modes: five supply-controlled modes, thirteen signal-controlled modes and continuous ON/OFF modes. The timing range extends from 0.1s to 99 days. One- and two-contact versions use an 18mm-wide housing for 35mm DIN rail mounting.
Select the contact count and 10A or 16A version with the required supply. The four common complete models use the W wide-range 12–240VAC/DC supply. Front-panel MD and arrow buttons provide the documented button-setting interface, with green power and red relay-output indication.

The web labels CDT6-X1 and CDT6-X2 identify the one- and two-contact arrangements. The technical table additionally describes an M 220VAC supply version; the ordering guide and common full-model table specify W and custom supply selections. Confirm the complete code when requesting another supply configuration.
| Mode | Function and chart relationship |
|---|---|
| 01 | Power-on delay: supply starts t, then the output closes. |
| 02 | Timed disconnection: the output closes at power-on, then opens after t. |
| 03 | Repeating cycle, OFF first: OFF interval t1 alternates with ON interval t2 while supplied. |
| 04 | Repeating cycle, ON first: ON interval t2 alternates with OFF interval t1 while supplied. |
| 05 | Pulse output: after power-on delay t1, the output closes for t2. |
| 06 | Externally controlled on-delay: S must remain active through t before the output closes; the chart shows a shorter input pulse producing no closure. |
| 07 | Off-delay triggered by the falling edge of S; the chart preserves the effect of further control transitions. |
| 08 | Timed disconnection triggered by the rising edge of S, with output interval t. |
| 09 | Timed output closure triggered by the falling edge of S, with output interval t. |
| 10 | On-delay and off-delay controlled by S, with separate t1 and t2 intervals. |
| 11 | Pulse conversion: successive S pulses alternate the output state. |
| 12 | Externally controlled repeating cycle, OFF first, using t1 and t2. |
| 13 | Externally controlled repeating cycle, ON first, using t2 and t1. |
| 14 | Externally controlled pulse output, with the t1 delay and t2 output interval shown in the chart. |
| 15 | Externally controlled delayed start and stop, with t1 and t2 intervals tied to the control pulses. |
| 16 | Externally controlled dual delayed disconnection; the chart identifies t1, t2 and the combined t1+t2 interval. |
| 17 | Externally controlled delayed start, with delay t before output activation. |
| 18 | Externally controlled delayed closure; use the illustrated S/R relationship and t interval. |
| 19 | Continuous ON: output remains closed while supplied. |
| 20 | Continuous OFF: output remains open while supplied. |
