Curtiss-Wright / Systran ADM1224F 24-Channel, Differential-Input, +/-10V, A-D Converter Module

The Curtiss-Wright/Systran ADM1224F is a 24-channel differential-input analog-to-digital converter module engineered for high-resolution data acquisition in industrial and scientific applications. The module accepts ±10V differential signals with high common-mode rejection, delivering deterministic sampling across all channels. Its modular architecture supports expansion to 120 channels in VME systems using the VMESC5 carrier or 144 channels in PC systems using the ISASC6 carrier.

Technical Specifications

Input Channels: 24 differential input channels

Input Voltage Range: ±10V

Architecture: Three sets of multiplexers, instrumentation amplifiers, and ADCs; one set supports 8 channels

Sampling: Complete deterministic sampling of all channels with 4-bit frame counter value included in ADC data output

Current Value Table: True "on-the-fly" access to latest ADC data

Input Configuration: High common-mode rejection via differential inputs; analog reference jumpers enable per-channel selection between differential and single-ended input modes

Key Features

Differential signal conditioning for increased accuracy and noise immunity

Deterministic sampling with frame counter sequencing for all 24 channels

Per-channel configurable input mode (differential or single-ended via reference jumpers)

On-the-fly access to current ADC values without interrupting sampling

Typical Applications Precise measurement and control systems requiring multi-channel differential data acquisition in VME or PC-based platforms.
