System compatibilityAS-B872-100 belongs to MODICON 800 series analog output module. Compatible with MODICON 984 series CPU,800 series backplane and RIO remote I/O rack system. It can cooperate with 800 series digital input, digital output and analog input modules. Suitable for chemical,water treatment,metallurgy,old production line process control system renovation and replacement as industrial spare part.

FunctionAS-B872-100 is 4-channel isolated analog current output module. It receives digital control commands from PLC CPU, converts digital signals into 4~20mA analog current signals to control field transmitters,valve positioners and regulators. It supports DIP switch configuration, with overcurrent protection and channel fault monitoring. Widely used for field analog actuator control of industrial process control system, serving as reliable analog output spare part.

InstallationCut off rack power before installation. Insert the AS-B872-100 module into MODICON 800 backplane slot and lock the card. Wire field 4-20mA output cables to the swing-arm terminal block. Set channel configuration via DIP switch, complete output calibration and channel test via Modsoft software before formal operation.

InterfaceBackplane bus connector,field analog signal swing-arm terminal block,channel status LED indicators for AS-B872-100 MODICON analog output module.

FeatureMODICON AS-B872-100 4-channel isolated 4-20mA analog output module,individual channel isolation,DIP switch parameter setting,built-in overcurrent protection,standard single slot rack design,swing arm terminal for convenient wiring,IP20 cabinet protection. This discontinued legacy industrial spare part used for old MODICON 984 PLC analog output control maintenance and replacement.

DiagnosticModule not recognized: check rack power supply,backplane contact and module insertion for AS-B872-100. Output signal deviation: check DIP switch setting,channel calibration and load resistance. No analog output: inspect field wiring,loop power supply and overcurrent protection trigger. Channel unstable output: check cable shielding and grounding to eliminate interference. Fault alarm: read module diagnostic information through Modsoft programming software.

Product BriefAS-B872-100 is MODICON 800 series 4-channel 4-20mA isolated analog output module. It converts PLC digital commands into analog current signals to regulate field valves and transmitters,classic spare part for legacy industrial process automation equipment overhaul.
