|---|---|---|---|---|---|---|
| Explanation: |
Product Family CDT6 - DIN rail time relay |
Series S - Repeating cycle timer with independently adjustable ON/OFF durations |
Contact Arrangement 1 - One changeover contact |
Contact Current Rating 10 - 10A contacts; AC-15 operational current 2.5A at 250VAC |
Power Supply M - 220VAC, 50–60Hz |
CDT6-S time relays repeatedly switch a control circuit ON and OFF with independently adjustable ON and OFF durations. Applications include periodic circuit energization, lighting and heating control. The range covers 0.1s to 100 days in an 18mm-wide housing for 35mm DIN rail installation.
The S-to-A1 connection selects the starting sequence: leave S open for ON first, or short S to A1 for OFF first. Choose one or two changeover contacts, the 10A or 16A contact version and the required supply.

The web labels CDT6-S1 and CDT6-S2 identify the contact arrangements. The four common full codes additionally identify current rating and supply; other selections follow the ordering guide.
Separate range/value knobs set the ON and OFF durations. The manufacturer specifies a ten-position delay range covering 0.1s to 100 days. Set each duration for the required duty cycle and use the chart corresponding to the S connection.
