System compatibilityAS-B814-108 belongs to MODICON B814 series relay output module. Compatible with MODICON 984 series CPU,backplane and other 800 series I/O modules. It can be used in local rack or remote RIO rack. Suitable for production line,packaging machinery,water treatment,chemical plant on-off actuator control renovation and replacement as industrial spare part.

FunctionAS-B814-108 8-point relay discrete output module. It receives control commands from PLC processor and drives built-in relays to switch field circuit. Relay contact provides isolated on-off signal to control solenoid valves,contactors and auxiliary relays. Each channel has independent fuse protection,built-in channel status monitoring. Widely used for industrial switch control of high voltage or different potential loads, serving as reliable relay output spare part.

InstallationCut off rack power and field load power before installation. Insert AS-B814-108 module into MODICON backplane slot and lock the card. Check gold finger contact condition. Wire field load cables to module terminal block. Configure module address,verify each relay action and complete function test before formal operation.

InterfaceBackplane bus connector,field load terminal block,channel status LED indicators for AS-B814-108 MODICON relay output module.

FeatureMODICON AS-B814-108 8-channel relay output module,galvanic isolation via relay contacts,independent channel fuse protection,LED status indication per channel,standard single slot rack design,anti-interference design for industrial workshop environment,IP20 cabinet protection. This discontinued legacy industrial spare part used for old MODICON 984 PLC system relay output maintenance and replacement.

DiagnosticModule not recognized: check rack power supply,backplane contact and module insertion for AS-B814-108. Relay cannot pull in: check backplane power,module configuration and PLC output command. No contact output: inspect load power supply,blown channel fuse and relay contact aging. Intermittent switching fault: check terminal loose,contact oxidation and mechanical vibration. LED abnormal: verify module hardware damage and backplane power supply.

Product BriefAS-B814-108 is MODICON B814 series 8-channel relay output module. It uses isolated relay contacts for on-off control of valves and contactors,classic spare part for legacy MODICON 984 automation equipment overhaul.
