Description

Isolation 0-20mA/4-20mA to RS485 or RS232 Converter (support Modbus RTU) Model selection: ISOAD A□ - □ Input and Channel Code Communication interface Channel code:01 ~ 08,number of channel 01:1 channel 4-20mA/0-20mA signal input 485: output is RS-485 interface 02:2 channel 4-20mA/0-20mA signal input 232: output is RS-232 interface 03:3 channel 4-20mA/0-20mA signal input ......... 08:8 channel 4-20mA/0-20mA signal input Note: If the selected product has less than 8 channels, it is the same externalview as that of AD A08, wiring scheme, and communication protocol. The only difference is that the selected one has less channels to measure data. Mode selection eg.1: Model:ISOAD A01-485 Indicates 1 channel, 4-20mA/0-20mA signal input,input is RS485 interface Mode selection eg.2: Model:ISOAD A06-232 Indicates 6 channel, 4-20mA/0-20mA signal input,input is RS-232interface Mode selection eg.3: Model:ISOAD A08-485 Indicates 8 channel, 4-20mA/0-20mA signal input,input is RS 485interface ISOAD Series 4-20mA to RS485/RS232 Converter Inroduction: (typical @ +25℃,Vs is 24VDC (It is recommended to use power supply under high stability and precision environment.) Input type: input current 4-20mA/0-20mA Precision: @ +25℃ (table 1) Input detuning: ±0.1 uA/℃ Temperature drift: ±15 ppm/℃ (±30 ppm/℃, max) Input resistance: < 250 Ω (4-20mA/0-20mA input current) Bandwidth: -3 dB 10 Hz Conversion rate: 10 Sps Common mode restraint (CMR): 120 dB(1kΩ Source Imbalance @ 50/60 Hz) Norm mode restraint (NMR): 60 dB (1kΩ Source Imbalance @ 50/60 Hz)
