Automated Logic M0320 Control Module

Automated Logic M0320 Control Module: Advanced Native BACnet Controller

The Automated Logic M0320 Control Module is a native BACnet standalone control unit engineered for complex multi-equipment HVAC and industrial automation architectures. Powered by a robust 32-bit microprocessor with a dedicated ARCNET communications co-processor, the M0320 delivers exceptional execution speed, high-resolution data conversion, and reliable peer-to-peer networking. Enclosed in a heavy-duty extruded aluminum housing that acts as an integrated ground plane, this module offers supreme noise immunity and electromagnetic protection for harsh electrical environments. Featuring 32 universal inputs, it seamlessly handles extensive sensor monitoring, control logic processing, and localized system integration.

Terminal Allocations & Wiring Designations

• Power Terminals (24VAC): Dedicated terminals for Hot and Common low-voltage system supply with onboard transient voltage surge suppression (TVSS).
• Universal Input Terminals (UI-1 through UI-32): Configurable software channels accepting 0–5 VDC, 0–20 mA (via shunt resistors), standard 10k thermistors, and binary dry contacts.
• Network Communications Terminals: Optically isolated connections mapped for high-speed ARCNET trunk lines (+, -, shield).

Applications

• Large-scale commercial building HVAC plant automation
• Central chiller and boiler plant optimization sequences
• Air Handling Unit (AHU) multi-zone environmental monitoring
• Industrial process control and centralized data acquisition nodes
• Marine and offshore climate control automation systems requiring robust noise isolation

Engineer Expert’s Guide

• Grounding Integrity: The extruded aluminum enclosure functions directly as an electrical reference ground plane. Ensure the chassis grounding lug is bolted securely to the control panel backplane with low-impedance copper braid to eliminate high-frequency marine/industrial common-mode interference.
• Shield Termination: When routing analog sensor lines across long engine-room or plant distances into the 32 universal inputs, terminate your cable shields strictly at one end (panel side) to prevent ground loops that corrupt low-level 10k thermistor or 4-20mA conversions.
• Firmware Synchronization: If integrating this module into an existing legacy ARCNET CMnet backbone alongside newer MS/TP trunks, verify your baud rate switches and jumper configurations prior to powering up the 24VAC circuit to prevent token dropouts on the ring network.

Frequently Asked Questions

What is the primary function of the Automated Logic M0320 control module?

The M0320 is a native BACnet standalone controller outfitted with 32 universal inputs, built explicitly to manage high-density sensor telemetry and control logic execution across complex multi-equipment commercial and industrial automation tasks.

Can the M0320 module support expansion input/output points?

Yes. The M0320 architecture supports up to five dedicated expansion modules (such as the MX0320), scaling total system point capacity up to 192 physical points.

What programming environment is required to configure the M0320?

The controller is fully compatible with Automated Logic’s EIKON® graphical programming environment, enabling engineers to build complex control loops, verify point execution, and compile control sequences without writing native code.

What power supply configuration does this module require?

The unit operates on a standard low-voltage supply of 24 VAC (±10%) at 50 to 60 Hz, drawing approximately 35 VA.
