The CI801 Fieldbus Communication Interface module links S800 I/O systems to higher‑level controllers.
It uses the PROFIBUS‑DPV1 protocol for reliable industrial communication across process plants.
This module manages signal processing, supervision, OSP handling, and I/O module configuration.
It provides galvanically isolated power to connected I/O modules for improved noise immunity.
HART pass‑through functionality enables HART device management over the same bus.
Hot Configuration In Run allows parameter changes without stopping system operation.
The module includes fused input power protection for safe and stable operation.
The CI801 is widely used in process industries with marine and hazardous area approvals.
The CI801 operates as a PROFIBUS DP‑V1 slave on industrial fieldbus networks.
It supports full supervision of the I/O ModuleBus for system diagnostics.
Isolated power output protects connected I/O modules from electrical interference.
Typical 24 V DC power consumption is 140 mA under normal operating conditions.
The module supports HART pass‑through for smart field device communication.
Hot Configuration In Run allows online setup changes without process interruption.
Input power is fused to prevent damage from overcurrent or short‑circuit events.
It is designed for use with ABB HI Controller systems in distributed I/O architectures.
No line or module redundancy is provided in this standard model.
Hot‑swap functionality is not supported by the CI801 module design.
The CI801 carries CE marking and complies with EN 61010‑1 and UL 61010‑1.
Hazardous location approvals include Class I Div 2, Zone 2, and ATEX Zone 2.
Marine certifications include ABS, BV, DNV‑GL, and LR for shipboard applications.
Operating temperature range is 0 °C to +55 °C (certified for +5 °C to +55 °C).
Storage temperature spans ‑40 °C to +70 °C for transport and long‑term storage.
Pollution degree is rated 2 per IEC 60664‑1 for industrial environments.
Corrosion protection meets ISA‑S71.04 G3 harsh environment standards.
Relative humidity tolerance is 5% to 95% non‑condensing.
Protection class is IP20 per EN 60529 and IEC 529.
The module complies with RoHS 2011/65/EU and WEEE 2012/19/EU directives.
Width of the CI801 is 85.8 mm (3.38 in.) for standard cabinet mounting.
Height including latch is 136 mm (5.35 in.) for rack installation.
Depth measures 58.5 mm (2.30 in.) to fit compact control panels.
Net weight is 0.3 kg (0.66 lbs.) for lightweight modular installation.
Mount the CI801 in a suitable S800 I/O rack or mounting position.
Connect 24 V DC fused power to the module input terminals carefully.
Attach the PROFIBUS‑DPV1 fieldbus cable to the communication port.
Ensure proper bus termination and grounding per ABB installation guidelines.
Wire I/O ModuleBus connections to downstream S800 I/O modules securely.
Verify environmental conditions stay within 0 °C to +55 °C during operation.
Maintain vertical mounting temperature limits at or below 40 °C where applicable.
Configure bus address and communication parameters via system software tools.
Confirm HART pass‑through and hot configuration settings before operation.
Perform a system test to validate communication and I/O module control.
