140CRA21100 DIO Drop Interface Module – Modicon Quantum
The 140CRA21100 is a DIO drop interface module from Schneider Electric. It belongs to the Modicon Quantum automation platform. This module uses a single port for remote I/O drops. It accepts 115/230 VAC supply voltage. The wide input range covers 85 to 276 VAC. It delivers 5.1 V output at 3 A nominal current. The design includes short-circuit and overvoltage protection. It handles 30 input words and 32 output words. The module works with 2, 3, 4, 6, 10, and 16-position backplanes. It supports RAM address, RAM, and checksum diagnostics at startup and runtime. Power dissipation is 11 W. A 7-pole terminal block handles wiring. This unit suits harsh plant environments with 4 kV ESD and 10 V/m field immunity. Operating temperature spans 0 to 60 °C. It carries UL 508, CSA Class 1 Division 2, GOST, C-Tick, and DNV approvals.
