HART pass-through:
Media: The system has pass-through functionality and can be connected either as local I/O (S800) or as Remote I/O.
Purpose: Makes HART data available for clients, e.g. Fieldbus Builder
Protocol: HART protocol
SW interface: Process data via 4 – 20 mA signal are I/O copied to application variables. HART data (status and diagnostic data) are available via “pass-through”.
HW Interface: S800 I/O modules AI845, AI895, AO845 and AO845 S900 I/O modules AI930/931 and AO930
OPC interface: Yes, via HART OPC server

Key Parameters and Features
Core Features & Advantages
-
Versatile Relay Outputs: The module's standout feature is its relay-based outputs, which allow direct switching of a wide range of AC/DC loads (24-230V). This provides greater flexibility than transistor outputs, as it can handle both AC and DC devices from a single module . The normally open contacts also provide a safe, "dry contact" isolation between the control system and the load.
-
Robust and Reliable Design: Each of the 8 channels is individually isolated with a rated isolation of 250 V . This protects the control system from field-side surges and noise, ensuring stable operation in harsh industrial environments. The relay mechanism itself provides a high level of protection against short circuits and overloads, often more resilient than solid-state outputs in such fault conditions.
-
Simple Integration and Maintenance: As part of the S800L series, the module offers simplified installation. It has no jumpers or switches to set; addressing is automatically configured when it's mounted on the DIN rail . The front panel features LEDs for each channel, providing a quick visual indication of the output state for easy on-site troubleshooting .
Typical Applications
The DO802-eA is widely used for robust, high-voltage switching in a variety of industries:
-
General Actuation: Driving contactors, motor starters, and small relays in manufacturing plants.
-
Process Control: Operating solenoid valves, indicator lamps, and alarms in chemical, oil & gas, and water treatment facilities.
-
Power Generation: Switching control circuits for auxiliary equipment and safety interlocks.
-
Building Automation: Controlling lighting, HVAC contactors, and access control systems.
Frequently Asked Questions (FAQ)
Q1: What is the primary function of the DO802-eA?
A: It is an 8-channel relay output module that provides isolated switching of AC/DC loads up to 230V, based on commands from an ABB Freelance DCS .
Q2: What is the key difference between the DO802-eA and a transistor output module?
A: The DO802-eA uses relay outputs, which are capable of switching both AC and DC loads and provide high isolation. Transistor outputs are typically limited to DC loads and higher switching speeds but are more susceptible to damage from overcurrent or voltage spikes.
Q3: What is the rated isolation voltage?
A: The module features a rated isolation voltage of 250 V .
Q4: What system is the DO802-eA compatible with?
A: It is part of the S800L I/O family and is specifically designed for use with the ABB Freelance DCS .
Q5: Does the module require any jumpers or switches for configuration?
A: No. The DO802-eA has no physical jumpers or switches. Its address and configuration are automatically set when it is installed on the DIN rail .
Q6: What do the LEDs on the front panel indicate?
A: The front panel LEDs show the status of each output channel, providing a quick way to confirm if the output is on or off . Standard module status LEDs (Fault, Run, Warning) are also present to indicate overall health .
Q7: What are the physical dimensions of the module?
A: The module has dimensions of approximately 58.5 mm x 102 mm x 86.1 mm and weighs about 0.24 kg .
