China Jfax31 4-20mA 1-5V Analog Input Conditioner Current Voltage Signal Isolator

Description:
JFAX31 intelligent voltage/ current isolator can convert DC voltage or current signal on site into needed signal to other instrument by isolated transmission.This instrument can use together with cell-combination instrument and DCS, PLCsystem. This instrument support signal isolation, signal conversion, signal distribution, signal process and etc. Thus improved the anti-interference
ability of automatic control system in industry procedure. So this system is reliable and stable.
Support display unit, the parameter and conversion of each channel can be programmed by touching button.
Features:
Signal channel, double channel.
It can measure 16 kinds of DC voltage(millivolt)/ current signal,
equipped with display unit, the users can setting input type as required.
Analog signal, RS485 output.
Input/output/power magnetic isolation.
Transmission accuracy(20ºC):0.2%FS±1word.
Response time: 50ms reached 90% of final value.
Full intelligent, digital, programmable.
Plug type terminal, convenience for installation and maintenance.
Standard 35mm DIN rail cassette installation.
Support program high-definition display unit. Support PV( measured value)
and SV( measured value) display in one screen. Displayed content
can be programmed, multiple combination, convenience for adjustment on field,
maintenance and debugging.
