| Class | MultiplexType Preset Time Limit Relay | |
| Type | LD72S | LD72SE |
| Rated Working Voltage | 85~265VAC/DC input free, other working voltage upon request | |
| Power Consumption | Less than 4.5VA | |
| Delay multiplying Factor | 0.01Sec 1Min/Sec 1HR/Min | |
| Delay Range | 1-9999 Times Delay Multiplying Factor | |
| Delay Mode | Default mode is positive delay, it also can be selected as delay down mode. Instantaneous type is without power cut memory function. |
|
| Display Mode | Sec flash indicator light works during delay process, action indicator light outputs after delay finish |
|
| Accuracy | Voltage affects error, repetitive error less than ± 50 PPM and preset error is 0 |
|
| Battery Back-Up | W/O | W(The function is also for time accumulator) |
| Weight And Outline Dimension |
About 150g, 72W* 72H* 126D | |
| Input Mode Of Reset Signal And Pause Signal | NPN or contact type, short time(ON) Impedance less than 3KΩ, open circuit(OFF) Impedance exceed 100KΩ. Signal inside adopts photoelectric coupling isolation |
|
| Reset Mode And Signal Width |
Power on reset, panel keying reset and bottom terminal reset, LED displays 0(positive mode) after reset or current dial code preset value(inverse code) | Panel keying reset and bottom terminal reset, LED displays 0(positive mode) after reset or current dial code preset value(inverse code). Power on reset(recover the delay value before power cut and the relay state) |
| Contact Capacity Of Inside Relay | When the delay value reach user's dial code preset value, contact of output relay changes. Contact capacity is impedance load max 5A/280VAC or 5A/28VDC(two groups of relays) |
|
| Operating Enviroment | Ambient Temperature: -10~+55 °C (nonfreezing) Ambient Humidity: 35~85%RH | |
| Noisy Immunity | AC2kV(between operating power terminals) or DC ± 500V, time accumulator works normally under sisturbance of 1uS impulse width |
|
| Service Life | Mechanical life: 5*106 times, electric life: 1*106 times | |
