8 Paperless Recorder1 Input3 analog input channels support various types of signal. The following options can beSelected to input through meter configuration.Voltage signal: 0~5V,Website: , 1~5V, 0~20mV, 0~100mV;Current signal: 0~20mA, 4~20mA;Thermal resistance: Pt100, Cu50;Thermocouple: B, E, J, K, S, T.2 Output1 isolated 24VDC feedback output can supply a current as much as 75mA.3 AccuracyReal-time display: ± 0.2% F. S.;Recall accuracy: ± 0.2% F. S.;Clock accuracy: ± 2S/Day4 Record Interval8 measuring ranges from 1 second to 240 seconds: 1/2/5/20/40/60/120/240 S.5 Record Capacity4MBit. The user can allocate it to three input channels through instrument configuration(0.5MBit per unit).6 Record TimeIf the power is ON, the total record time T of every channel can be calculated byThe Record Interval t and Record Capacity n. See the formula as follows:T=0.74× N× T;Where: T: Day;T: S;N: M, it's value can be 0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5 or 4.0 (optional).For example: In case n=4.0, t=240S, this channel can record for T=710.4 days.7 Alarm Output2 passive Contact Outputs. Contact Capacity: 1A 30VDC.8 CommunicationRS485 mode: Complying with open MODBUS RTU slave protocol, and the baud rate can beSet to 1200 bps, 4800 bps, 9600 bps, 19200 bps, 38400 bps or 57600 bps.9 ScreenDisplay Resolution: 192× 64 Scan frequency: 1Hz10 Power SupplyRated AC supply voltage: 0.2A @ 90~260VAC, 45~55Hz.11 SizeOutline size: 160mm(Width)× 80mm(Heigh)× 48mm(Depth);Hole size: 152mm× 76mm.12 Net weight≤ 1.0kg.13 Storage conditionTemperature: -20~60º C.
