Product Name: Display Digital LED Counter Sensor Model NO.: LD72J Theory: Digital Usage: Industrial Type: Counter Weight: 150g Trademark: LIRRD Transport Package: Carton Specification: 72mm*72mm Origin: Yueqing, Zhejiang, China HS Code: 9029109000 Product Description ClassMultiplex Type Preset CounterTypeLD72JLD72JERated Working Power85~265VAC/DC input free, outher working voltage upon requestCounting Multiplying Factor×1, ×10, ×100,×1,×10,×100,( 1 denotes to count and plus 1 for 1 input signal, 10 denotes to count and plus 1 for 10 input signal,100 denotes to count and plus 1 for 100 input signal, × denotes posifive mode × denotes in verse mode)Counting Range1-999900, 4 bits dial code preset, 1 bit counting multiplying factor setPower Cut Memory FunctionW/OW(The function is also for time accumulator)Counting Speed≤60cpsWeight and outline dimensionabout 150g, 72W× 72H× 126DSignal Input ModeNPN or contact type, short time (ON) impedance less than 3kΩ,open circuit (OFF) impedance exceed 100kΩ. Signal inside adopts photoelectric coupling isolationReset Mode And Signal WidthPower on reset, panel keying reset and bottom terminal reset, LED displays 0 (positive mode) after reset or current dial code preset value (inverse code)Power 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 CapacityOf Inside RelayWhen the counting value reach user's dial code preset value, contact of output relaychanges.Contact capacity is impedance load max 5A/28VAC or 5A/28VDC (two groups of relays)Power output of sensorMax DC12V, 20mAOperating EnvironmentAmbient Temperature: -10~+55 °C (nonfreezing) Ambient Humidity: 35~85%RHNoisy ImmunityAC2kV(between operating power terminals) or DC ± 500V,time accumulator works normally under sisturbance of 1uS impulse widthService LifeMechanical life: 5*106times, electric life: 1*106times
