The Phoenix Contact 2736628, also known by its designation ASI MA IL UNI, is an AS-Interface (AS-i) Gateway module designed for the Inline I/O system. It acts as an AS-i master, enabling the seamless integration of an AS-Interface network into a higher-level Inline station. This allows communication between AS-i field devices (slaves) and various automation protocols such as PROFIBUS, PROFINET, DeviceNet, or EtherNet/IP, depending on the head station used in the Inline assembly.

Product Specifications

Model Number: 2736628 (ASI MA IL UNI)
Function: AS-Interface Gateway / AS-i Master
AS-i Specification: Version 2.1 (Extended Specification)
Slave Capacity: Supports up to 62 AS-i slaves
Local Bus Interface: Inline local bus with a transmission speed of 500 kbps
AS-i Transmission Speed: 167 kbps
Protection Rating: IP20 (Requires installation in a control cabinet)
Ambient Temperature (Operation): -25 °C to 55 °C
Current Consumption: Typically 200 mA (drawn from the AS-i network)
Electrical Isolation: 500 V AC (50 Hz, 1 min) between AS-i and the local bus
Dimensions: Width 73.2 mm, Height 119.8 mm, Depth 71.5 mm
Connection Method: Spring-cage connection for easy, vibration-resistant wiring

Product Advantages

High Integration: Specifically designed for the Phoenix Contact Inline system, allowing users to combine AS-i bus technology with other I/O modules in a single station.
Extensive Diagnostics: Features a built-in 3-digit, 7-segment display and multiple LEDs to show status, addresses, and error messages directly on the device.
Ease of Maintenance: Like all Inline modules, it features pluggable wiring and automatic power supply connection via the backplane when snapped onto the DIN rail.
Flexible Configuration: The AS-i network can be configured directly on the module using two integrated pushbuttons (Mode/Set) or through parameterization via software.
Master Functionality: Capable of managing a full AS-i 2.1 network, significantly expanding the I/O capabilities of the parent Inline system.

Important Considerations

Environmental Protection: With an IP20 rating, this module must be protected against moisture, dust, and conductive contaminants within a NEMA or IP-rated enclosure.
Power Supply Requirements: The module draws its power from the AS-i network; ensure the AS-i power supply is properly sized for the total number of connected slaves and the gateway itself.
EMC Compliance: This is a Class A product. In domestic environments, it may cause radio interference, requiring the user to take adequate protective measures.
Wiring Safety: Always use the specified stripping length (8 mm) and ensure that spring-cage connections are fully engaged to prevent intermittent signals.
Legacy Status: While still widely used, always check for the latest firmware and software (like CMD or Studio) to ensure compatibility with modern PROFINET or EtherNet/IP controllers.

Product Applications

The ASI MA IL UNI is widely applied in decentralized automation architectures where simple sensors and actuators need to be networked efficiently.

Conveyor and Logistics Systems: Connecting a large number of digital sensors and motor starters along a production line to a central PLC.
Packaging Machinery: Managing high-speed I/O transitions for sorting and packaging tasks using the AS-i bus.
Building Automation: Interfacing specialized AS-i sensors for HVAC or lighting control into a standard industrial Ethernet or fieldbus backbone.
Process Industry: Used in water treatment or food processing facilities where modular I/O expansion is required to accommodate field instrumentation.
