Description
Product Introduction
1TNE968901R0100 is DC551 digital input expansion module of ABB AC500-eCo PLC system with fixed screw terminal structure, used for expanding discrete signal input points of AC500-eCo CPU, applied in cabinet assembling and spare replacement of automation projects.
Model Definition
1TNE is unified part prefix for ABB AC500 series expansion modules. 968901 stands for base hardware specification of DC551 input module. Suffix R0100 represents factory standard fixed terminal version with commercial model DC551.
Technical Specifications
Power supply sourced from PLC backplane bus, input signal DC24V. Onboard 16-channel digital input with sink/source compatible wiring mode. DIN rail installation, operating ambient temperature 0℃~+55℃, storage temperature -25℃~+70℃, IP20 protection grade for cabinet inner installation.
Interface and Communication Configuration
Front side fixed screw terminals for field sensor and proximity switch wiring. Backplane gold finger connector for plugging onto base terminal unit and data interaction with CPU via internal system bus, no independent external communication port.
Core Functions
Collect DC24V switch signals from field sensors, limit switches and proximity detectors, transmit collected digital signals to main CPU through internal backplane bus to realize remote signal expansion of control system. Front panel LED indicators display channel on-off status for convenient on-site fault inspection.
Application Scenarios
Matched with PM554/PM564/PM573 series AC500-eCo CPU, used for signal expansion of wastewater treatment equipment, packaging machinery, pump and fan control cabinets and general factory automation equipment.
Operation and Maintenance Instructions
Disconnect PLC main DC24V power before pulling out or wiring the module. Conduct quarterly maintenance to clear terminal dust with dry compressed air and check terminal screw tightness. When channel input abnormal, inspect field sensor and connecting cable first before module replacement.
