System compatibility140CRA21210 belongs to MODICON Quantum series DIO drop remote I/O interface module. Compatible with MODICON Quantum CPU,Quantum backplane and series I/O modules. It is used for remote distributed I/O expansion via Modbus Plus bus. Suitable for chemical plant,water treatment,power plant,large-scale process control remote signal collection renovation and replacement as industrial spare part.

Function140CRA21210 DIO drop remote I/O adapter. It communicates with main Quantum CPU through Modbus Plus bus,realizes remote rack I/O data exchange. It collects discrete and analog signals from remote I/O modules and transmits to main CPU; meanwhile receives control commands from main CPU and outputs to field equipment. Built-in bus communication monitoring,module self-diagnosis and fault alarm function. Widely used for long-distance distributed I/O expansion of large industrial control systems, serving as reliable remote I/O interface spare part.

InstallationCut off rack power before installation. Insert 140CRA21210 module into Quantum backplane slot and lock the card. Check gold finger contact condition. Connect Modbus Plus communication cable and AC power supply. Configure network station address and I/O mapping,complete online communication test before formal operation.

InterfaceBackplane bus connector,Modbus Plus bus port,AC power terminal,run/fault/bus status LED indicators for 140CRA21210 MODICON DIO drop interface module.
