Schneider Electric DTA202ASHDTA200 PLC Module

Schneider Electric DTA202ASHDTA200 is a Modicon backplane assembly for TSX Compact/984-series PLCs, pairing a five-slot AS-HDTA-200 primary subrack with a two-slot DTA202 expansion subrack to form a compact, scalable I/O backplane. The AS-HDTA-200 base backplane accepts a single CPU and up to three I/O modules, while the DTA202 expansion adds two I/O slots and must be placed as the last rack in a linear configuration. Compatible with Modicon Micro CPUs, including models such as 512/612, and TSX Compact I/O modules, this combination is designed for 984/A120 Compact systems. The AS-HDTA-200 base measures 142 mm high by 213.4 mm wide by 31 mm deep, while the DTA202 expansion measures 142 mm high by 91.5 mm wide by 31 mm deep. This DTA200-based backplane assembly enables scalable I/O expansion in space-constrained automation installations, offering a modular path from a single-CPU setup to a multi-module TSX Compact configuration.
