| Explanation: |
Product Family CDT6 - DIN rail time relay |
Series M - Multifunction time relay with modes A–J |
Contact Arrangement 1 - One changeover contact |
Contact Current Rating 10 - 10A contacts; AC-15 Ie 2.5A at 250VAC |
Power Supply M - 220VAC, 50–60Hz |
CDT6-M combines ten selectable functions in an 18mm-wide DIN rail timer. Five modes respond to the supply, four timed modes use the S control input and one mode converts input pulses into alternating output states. Applications include industrial equipment, lighting, heating, motor and fan control circuits.
Three front knobs select the function, time range and delay value. The timing range extends from 0.1s to 10 days, with separate ON/OFF positions. Choose one or two changeover contacts and the required contact rating and supply through the complete model code.
| Field | Codes and meaning |

|---|---|---|---|
| CDT6-M110M | 1 | 10A / 2.5A | 220VAC |
| CDT6-M210M | 2 | 10A / 2.5A | 220VAC |
| CDT6-M116W | 1 | 16A / 5A | 12–240VAC/DC |
| CDT6-M216W | 2 | 16A / 5A | 12–240VAC/DC |
All four common models provide modes A–J. The web labels CDT6-M1 and CDT6-M2 identify one- and two-contact versions; the full code additionally specifies current rating and supply. Other choices follow the ordering guide.
| Mode | Function | Operation |
|---|---|---|
| A | Power-on delay | Applying Un starts delay t; the output closes when t expires. Removing Un opens the output. S has no effect. |
| B | Timed disconnection after power-on | Applying Un closes the output immediately and starts t. The output opens after t, or immediately if Un is removed first. S has no effect. |
| C | Repeating cycle, OFF first | Applying Un starts an OFF interval t, followed by an ON interval t. The cycle repeats until Un is removed. S has no effect. |
| D | Repeating cycle, ON first | Applying Un closes the output for t, followed by an OFF interval t. The cycle repeats until Un is removed. S has no effect. |
| E | Off-delay, S falling edge | With Un present, closing S closes the output. Opening S starts t; the output opens when t expires. Closing S again during timing resets the delay. |
| F | Timed output, S rising edge | With Un present, closing S closes the output and starts t. The output opens after t. Further S closures during timing do not restart the delay. |
| G | Timed output, S falling edge | With Un present, opening S closes the output and starts t. The output opens after t. Further S transitions during timing do not restart the delay. |
| H | On-delay and off-delay | With Un present, closing S starts a delay before the output closes. Opening S starts a delay before the output opens. Both delays use the selected t. |
| I | Pulse conversion | With Un present, each S closure changes the output state. |
| J | Delayed pulse | Applying Un starts delay t. After t, the output closes for 0.5s and then opens. |
