| Part Number: | CDT6 | - | EC | 1 | 10 | M |
|---|---|---|---|---|---|---|
| Explanation: |
Product Family CDT6 - DIN rail time relay |
Series EC - Dual-function timer: power-on delay or timed disconnection after power-on |
Contact Arrangement 1 - One changeover contact |
Contact Current Rating 10 - 10A contact version; AC-15 operational current 2.5A at 250VAC |
Power Supply M - 220VAC, 50–60Hz |
CDT6-EC provides two selectable timing functions in an 18mm-wide housing: power-on delay and timed disconnection after power-on. DIP switches select the function and timing band, while the front knob adjusts the delay. The 0.1s to 10-day range suits industrial control circuits for lighting, heating, motors and fans.
The documented common model CDT6-EC110M has one 10A changeover contact and a 220VAC rated supply. The family overview also identifies 24VDC operation; specify the required supply and obtain the applicable terminal assignment for that configuration.

| Common full model | Functions | Output | Supply |
|---|---|---|---|
| CDT6-EC110M | Power-on delay; timed disconnection after power-on | One changeover; Ith 10A, Ie 2.5A | 220VAC, 50–60Hz |
| Selection | Sequence |
|---|---|
| A: power-on delay | Applying supply Un starts delay t. The output closes when t expires. Removing Un opens the output. |
| B: timed disconnection | Applying Un closes the output immediately and starts t. The output opens after t; removing Un before t expires also opens the output. |
