At its core, the ACC-72EX acts as a bridge between analog sensors and digital control systems, converting raw signals from thermocouples, pressure transducers, or accelerometers into actionable data. Its CANopen and MODBUS RTU compatibility ensures plug-and-play integration with PLCs, HMIs, and industrial PCs, while hot-swappable design minimizes downtime during maintenance. The module’s wide input range (±10V) and EMI/RFI shielding make it robust in electrically noisy environments, such as steel mills or automotive assembly lines.


What sets the ACC-72EX apart is its scalable architecture, allowing users to daisy-chain multiple modules via Delta Tau’s UMAC system for large-scale deployments. For example, a single PMAC2A-ETH controller paired with three ACC-72EX modules can monitor 216 analog points simultaneously, as demonstrated in petrochemical plants for real-time process optimization. Backed by Delta Tau’s reputation for reliability, the ACC-72EX ensures consistent performance in harsh industrial conditions.

Key Features and Benefits


  1. Ultra-Precise Signal Conditioning
    The ACC-72EX employs auto-zero calibration and programmable gain amplifiers to eliminate drift and noise, ensuring accurate readings even in low-level signal applications. For instance, in semiconductor wafer inspection systems, the module’s 16-bit resolution enables detection of micron-level thickness variations.
  2. Multi-Protocol Connectivity
    With native support for CANopen and MODBUS RTU, the ACC-72EX integrates seamlessly with both Delta Tau’s motion controllers and third-party devices. This flexibility allows users to retrofit legacy systems or build hybrid architectures, as seen in automotive paint shops where MODBUS RTU is used for conveyor speed control alongside CANopen for robotic arm synchronization.
  3. Scalable and Redundant Design
    The module’s daisy-chaining capability via Delta Tau’s UMAC system supports up to 254 nodes per network, making it suitable for distributed control systems. Redundant power inputs ensure continuous operation during transient voltage fluctuations, critical for applications like oil rig monitoring.
  4. Hot-Swap Capability
    Engineers can replace faulty ACC-72EX modules without powering down the entire system, reducing mean time to repair (MTTR) by 50% compared to non-hot-swappable alternatives. This feature is particularly valuable in 24/7 manufacturing environments.
  5. EMI/RFI Immunity
    The module’s shielded enclosure and isolated channels mitigate electromagnetic interference, ensuring stable performance in proximity to high-power equipment. This is critical in steel mills, where induction furnaces generate intense electromagnetic fields.
