ABB DI811 3BSE008552R1 Digital Input Module

Input Channels:16 digital inputs Channels are divided equally into two isolated groups of eight.

Voltage Requirements: Each channel is configured for 48 V DC power supply with current-sinking as its nature.

Input Impedance: At approximately 10kΩ.

Response time: The response time is < 1 ms.

Operation Temperature: - 25 ° C to + 60 ° C.

The 36-60V DC wide voltage input of DI811 is compatible with a variety of industrial sensor signals, and will not cause false triggering due to voltage change.

EMC strengthening: DI811 EN 61000-6-4/6-2 certified, high frequency noise and the high level of electrostatic discharge (ESD) in the industrial environment have resistance to CE, UL certification is complete,.

Modular expansion: ABB DI811 is the core unit of the S800 I/O system and it can be used in combination with AI810 analog input modules, DO810 digital output modules, etc. Only 1 system supports 256 I/O channels.

Channel status indication: The input status (ON or OFF) and fault alarm are indicated simultaneously through an independent LED for each channel of DI811(3BSE008552R1).

Self-diagnosis: DI811 (3BSE008552R1) has self-test every certain period of time, through the internal circuit of the module (such as optoelectronic isolation fault, power fail), the output of the diagnostic code by the communication interface.

Explosion proof certification: DI811 (3BSE008552R1) is approved for ATEX Zone 2 (specific type has to be verified) and IECEx Zone 2 and for explosive gas and dust environments.

Marine certificate The DI811 (3BSE008552R1) has been certified by ABS, BV, DNV GL and other China certification societies, and can be used in the automation system of offshore platforms and ships.

In the automation production such as automobile making and food processing, DI811 is used for signal collection in the limit position switches of robot arm, sensor in conveyor belt, and emergency stop button, to realize production lines starting, stopping and safety interlock with precision.

The DI811 can gather the status signals of pressure switch, temperature alarm contact and circuit breaker in the petrochemical system and power system to work with DCS system and realize closed loop control and safety interlocking of process parameters.

In the high temperature, high humidity environment of metallurgical, paper making and other industries, across the large temperature range of operation of DI811 anti-jamming design makes signal acquisition stable, do not wear the rolling mill position sensor, paper machine tension sensors.
