ABB DI821 3BSE008550R1 Digital Input
Key SpecificationsVOGI
1. Input Characteristics
8 channels: Supports AC (AC 164-264V / 11mA) and DC (DC 175-275V / 1.6mA) inputs.
Structure: Each channel contains current limiting elements, EMC protection and optical isolation barriers.
2. Monitoring Function: Channel 1 monitors channels 2-4, channel 8 monitors channels 5-7; LED alarm is triggered when voltage disappears, error signal is read through ModuleBus.
3. Redundancy and communication: Support redundancy configuration (e.g. AC800F system), integrated ModuleBus protocol, compatible with ABB AC800 series.
4. Certification & Service: CE certification, 1 year warranty.
Key FeaturesVOGI
1. 8-channel independent input: ABB DI821 supports AC (AC 164-264V/11mA) and DC (DC 175-275V/1.6mA) signal inputs, compatible with industrial-grade high and low voltage scenarios.
2. Channel structure: Each channel of ABB DI821 integrates current limiting elements, EMC protection elements and optical isolation barriers to ensure signal stability and anti-interference capability.
3. Voltage monitoring function: Channel 1 and 8 can monitor other channels separately (Channel 1 monitors 2-4, Channel 8 monitors 5-7), triggering LED alarms and transmitting error signals via ModuleBus when voltage is abnormal.
4. Redundant Configuration: ABB DI821 supports redundant control with AC800F and other systems to ensure continuous system operation in industrial scenarios.
5. Integrated ModuleBus protocol: ABB DI821 is compatible with ABB AC31 and AC800 series PLCs, supports S800 I/O system expansion, and can realize redundancy through MTU modules (such as TU840). Communication.
6. Long distance connection: ABB DI821 supports up to 600 meters shielded cable connection, suitable for distributed industrial equipment layout.
7. High isolation capability: Rated insulation voltage of 50V, dielectric test voltage of 500V AC (1 minute) to meet the requirements of harsh electrical environments.
8. Low power consumption: Typical power consumption of 3.1 watts, external 24V power supply requires only 25mA, energy-saving and suitable for compact control cabinets.
