Description
Introduction to ABB DO802 3BSE022364R1 Digital Output Module
ABB DO802 3BSE022364R1 is an 8-channel digital output module in the ABB ADVANT-800XA DCS control system S800 I/O series. It is used to convert digital instructions issued by the controller into switch signals that can drive external execution devices. It is the execution layer interface between the control system and field devices.
core parameters
ABB DO802 3BSE022364R1 DIGITAL OUTPUT RELAY
Number of channels: 8 independent digital output channels, divided into two groups of 4 channels each, each equipped with independent voltage monitoring inputs.
Output type: Relay output (dry contact), normally open (NO) configuration, passive contact.
Voltage level: 24VAC to 230VAC, with a wide range of applications, can directly drive AC loads.
Load capacity: AC 250V/5A or DC 30V/2A level, supporting inductive loads such as solenoid valves and contactor coils.
Response time: Typical value ≤ 2ms, meeting the requirements of high-speed start stop control.
Electrical isolation: The isolation voltage between channels is ≥ 2500V, and the isolation voltage between modules and buses is ≥ 1500V, effectively suppressing common mode interference.
Communication interface: Supports Profibus DP, Modbus RTU/TCP, and Ethernet/IP protocols, and communicates with S800 controller through Modulus Bus.
physical properties
Dimensions: 102mm × 119mm × 45mm.
Weight: Approximately 0.25kg.
Protection level: IP20, suitable for installation inside control cabinets.
Working temperature: The maximum ambient temperature is 55 ℃. It is recommended to reduce the rating to 40 ℃ to ensure long-term stable operation.
Power consumption: Typical full load power consumption is about 5W.
Installation method: Standard DIN rail installation, to be used in conjunction with TU810, TU812, TU814, TU818, TU830, TU833, TU838, TU850 and other terminal units to ensure electrical isolation performance.
Main functional features
Drive execution equipment: Receive instructions from 800XA controllers such as PM802F and PM866A to drive on-site devices such as relays, solenoid valves, contactor coils, motor start stop circuits, indicator lights, alarms, etc. The output characteristics of relays make them particularly suitable for driving inductive loads such as solenoid valves and contactors, which is a key difference from transistor output modules (such as DO810).
Channel status indication: Each channel is equipped with LED indicator lights, which can quickly locate the faulty channel without the need for additional diagnostic tools.
Multiple protection: Built in short-circuit protection and overload alarm function, automatically cutting off output and reporting bus in case of fault, reducing the risk of shutdown.
Hot swappable support: All S800 I/O modules support hot swappable replacement without cutting off the power supply to the I/O station system.
Redundancy capability: In a redundant configuration, when a DO module fails, the signal will be automatically cut off to a low level, and the normal DO module will continue to output at full load, ensuring the continuous operation of the system.
Parameterized configuration: Supports parameter configuration through the bus, including tag name, signal range, filtering time, etc. The filtering time supports four options of 2/4/8/16ms, effectively suppressing on-site noise interference.
Start self check: Automatically check the electrical ID of the module when powered on, and do not enter the running state when it does not match the configuration, to prevent control abnormalities caused by mismatches.
Comparison with digital output modules of the same series
DO801 (3BSE020510R1) is a 16 channel 24VDC relay output with the highest channel density. DO802 is an 8-channel 24-230VAC relay output with a wider voltage range, designed specifically for AC load scenarios. DO810 is a 16 channel 24VDC transistor output, suitable for pure resistive loads with high-frequency switches. DO814 is an 8-channel 24VDC transistor output. The core positioning of DO802 is to exchange fewer channels for wider AC voltage adaptability.
Typical application scenarios
Power industry: Start stop control of auxiliary equipment for generator sets, driving of auxiliary contacts for circuit breakers.
Chemical industry: switch drive for reactor feed valve, discharge valve, safety valve, solenoid valve control.
Metallurgical industry: synchronous control of vibration solenoid valve for continuous casting machine crystallizer.
Manufacturing industry: Start stop of production line equipment, sorting control of conveyor lines, high-speed operation of packaging machinery.
Water treatment: Pump station valve control, dust removal system pulse valve drive.
Rail transit: Relay drive for signal lights, switches, and door status.
