Relay Application

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
