System compatibilityAS-B875-101 belongs to MODICON 984 series analog input module. Compatible with MODICON 984 CPU,984 backplane and related rack power supply modules. It collects field analog signals for 984 PLC system. Suitable for chemical plant,water treatment,energy plant,packaging machinery pressure,flow,level,temperature signal acquisition renovation and replacement as industrial spare part.

FunctionAS-B875-101 4-channel analog input module. It receives 4~20mA current signals from field transmitters such as pressure sensor,flow meter and level transmitter. The module converts analog current signal into digital value and transmits to PLC CPU for logic calculation and data recording. Built-in signal overrange detection and module self-diagnosis function. Widely used for analog field signal collection in continuous process control, serving as reliable analog input spare part.

InstallationCut off rack power and field transmitter power before installation. Insert AS-B875-101 module into MODICON backplane slot and lock the card. Check gold finger contact condition. Connect field 4-20mA signal wiring to terminal block. Configure channel scaling parameters,verify signal reading accuracy and complete function test before formal operation.

InterfaceBackplane bus connector,4-channel analog input terminal block,channel status and fault LED indicators for AS-B875-101 MODICON analog input module.

FeatureMODICON AS-B875-101 analog input module,4 points 4-20mA current input,12-bit high precision conversion,250Ω built-in resistor,overrange alarm,standard single slot rack structure,industrial anti-interference design. This discontinued legacy industrial spare part used for old MODICON 984 PLC system analog signal acquisition maintenance and replacement.

DiagnosticModule not recognized: check rack power supply,backplane contact and module insertion for AS-B875-101. Signal reading zero: inspect transmitter power supply,signal wiring and loop breakage. Inaccurate analog value: check loop impedance,scaling configuration and electromagnetic interference. Overrange alarm: verify field signal exceeds 4~20mA range. Intermittent signal fluctuation: check shielding grounding and terminal loose.
