1.JC - JC, 7/12 - 7/11 as common impulse relay. Its function is:
A. current surge current action; B. returns C. manual reduction.
2.JC - JC, 7/21 - 7/22 are based on the functions of 7/11 - JC, JC - 7/12, and the delay function is also added.:
The A. terminal of the short delay, the automatic reset action after;
B, the terminal, and short connection time relay action, delay in the process of IF signal has disappeared relay will end delay, no action.
Relay 3. The main characteristics are: strong capability of anti interference of the ripple, the filament of cold resistance and thermal resistance difference caused by current anticlimax does not enable relay error return.
Main technical parameters
Rated DC current: 220V, 48V, 110V.
See table for action and return current.
Maximum long-term stable current see table.
| Delay time: | 2 ~ 10s, continuous adjustable. |
| Contact capacity: | No more than 250V voltage, the electric current does not exceed 5a, the time constant for 5 + 0.75ms DC sense of load, the product output contact breaking capacity is 50W. The output contact of the product can be reliable and return 5 x 104 times under the load condition of the above mentioned conditions. The output contact allows for a long time 5A. |
| Medium strength: | Products of each conductive terminal even together, on the exposed uncharged metal part or between the shell, bear 2000V (RMS) 50Hz AC voltage which lasted 1 minute test without dielectric breakdown or flashover phenomenon. |
