| Class | LT4I Intellectual Type Time Limit Time Relay | |
| Type | LT4I -AB (R denotes double cycle type for option) |
LT4I -CD (R denotes double cycle type for option) |
| Rated Working Voltage | 85~265VAC/DC input free, other working voltage upon request | |
| Power Consumption | Less Than 5W | |
| Contact Capacity | 2 groups of relay output, capacity: impedance load max 5A/250VAC or 5A/28VDC | |
| Time Range | 0.01 Sec- 9999 Sec(Choose bottom terminals) | 0.01 Sec- 99Hr/59Min(Choose bottom terminals) |
| Time Scale Mode | Decimal System | Sexagesimal |
| Display Mode | Power indicator light, action indicator light of relay, and bicolor digital displays the current delay |
|
| Data Setting Storage | Adopting EEPROM, the action mode of relay and data preset storing time not less than 10 years | |
| Action Mode Of Relay | Four kinds of modes(Remark 1) | |
| Accuracy | Voltage affects error, repetitive error less than ± 50PPM and preset error is 0 | |
| Signal Input | Reset and pause signal input is contact or NPN (emitter to common terminal 1), adopting photoelectric coupling solation, signal width should not less than 0.02 Sec |
|
| Operating Enviroment | Ambient Temperature: -10~+55 °C (nonfreezing) Ambient Humidity: 35~85%RH | |
| Service Life | Mechanical life: 5*106 times, electric life: 1*106 times | |
| Weight | About 121g | |
| Remark 1 : Output relay can preset any of the four working modes,see the following table | ||
| Code Of Preset Mode | Working mode instruction for outputting relay | |
| H-. on; d-.of | Starting delay after power on, relay closes after reaching preset value | |
| H-. of; d-.of | Not delay after power on, to make it work through panel reset key or bottom reset terminals, relay closes after reaching preset value |
|
| H-. on; d-.on | Starting delay after power on, relay closes and it releases after reaching preset value | |
| H-. of; d-.on | Not delay after power on,relay closes, to make it work through panel reset key or bottom reset terminals,relay releases after reaching preset value | |
| To set the above four kinds of working modes for relay as the following operations: for LT4I press reset without stop before power on, after power on,LED displays any of the above four codes, to set the needed one via "∧" "∨" key,then press "set" to confirm, cut off the power and power on again. |
