Allen-Bradley 1797-CEC Isolator and Connector Module Product Information

Product Description

Allen-Bradley 1797-CEC is an integrated isolator and connector module in Rockwell Automation's FlexEx I/O system, designed for safe signal transmission and device connection in industrial field environments. This module combines signal isolation and quick-connect functions, enabling electrical isolation between field sensor/actuator signals and the control system while simplifying wiring through standardized interfaces. It is suitable for signal transfer and protection in FlexEx distributed I/O networks, enhancing the anti-interference capability and installation efficiency of industrial automation systems.

Detailed Parameters

Isolation Performance：Supports 250V AC continuous isolation between signal and power, with common-mode rejection ratio (CMRR) ≥100dB (50Hz), effectively blocking ground potential differences and electromagnetic interference.
Interface Configuration：1 M12 circular connector (8-pin, A-coded) for field device connection; 1 1797 series backplane connector for system integration, supporting hot swapping.
Signal Types：Compatible with digital signals (24V DC) and analog signals (4-20mA, 0-10V), adaptable to signal transmission of sensors, solenoid valves, etc.
Transmission Rate：Supports up to 125kbps signal transmission, meeting real-time communication requirements of distributed I/O.
Operating Environment：Operating temperature -25℃~70℃, storage temperature -40℃~85℃, relative humidity 5%~95% (non-condensing), protection class IP67 (suitable for on-site installation, non-submerged).
Power Requirements：Powered via backplane bus, no external power supply needed, power consumption ≤1.5W.
Dimensions：Diameter×height approximately 45mm×80mm, M12 thread-mounted, compatible with standard sensor mounting brackets.
Certification Standards：UL 508, CSA C22.2 No.14, ATEX, IECEx certified, compliant with EN 61010-1 industrial equipment safety standards.

Advantages and Features

Integrated Design：Combines signal isolation and quick connection, replacing the traditional "isolator + terminal block" combination, reducing component count and system failure rates.
High-Protection On-Site Installation：IP67 rating allows direct mounting on machine surfaces or near sensors without additional enclosures, adapting to humid, dusty industrial environments (e.g., food washing areas, automotive painting workshops).
Strong Anti-Interference：High isolation voltage and CMRR ensure stable signal transmission in motor/frequency converter-dense areas, avoiding measurement errors caused by ground loops.
Rapid Installation & Maintenance：M12 connector supports "plug-and-play," reducing installation time by 60% compared to traditional wiring; hot-swap design enables on-line module replacement, shortening downtime.
Flexible System Adaptation：Compatible with all FlexEx I/O modules, seamlessly integrating with 1756-ControlLogix or 1769-CompactLogix systems, supporting expansion of distributed control architectures.

Application Fields

Automotive Manufacturing Workshops：In welding production lines, connects proximity sensors with FlexEx I/O modules; isolation resists strong electromagnetic interference from welding robots, ensuring accurate transmission of workpiece positioning signals.
Food & Beverage Processing：Installed near washing areas, connects level sensors, flow switches with control systems; IP67 protection withstands periodic 冲洗，isolation prevents ground faults caused by water corrosion.
Packaging Machinery：Used for signal transfer in labeling machines and filling machines, connects servo motor encoders with I/O systems; quick-connect design facilitates module 插拔 during equipment maintenance.
Logistics & Warehousing Equipment：On stackers in automated warehouses, connects travel switches with distributed I/O; adapts to vibration environments of mobile equipment, ensuring signal stability.
Metallurgical Auxiliary Equipment：Adapts to temperature sensor signal transmission around rolling mills; isolation protection in high-temperature environments avoids signal drift, ensuring equipment temperature control accuracy.

Notes

Use a dedicated torque wrench to tighten M12 connectors (3.5Nm recommended) to prevent water ingress (loose) or thread damage (over-tight).
On-site wiring must use shielded M12 cables; the shield layer must be reliably connected to the module housing to enhance anti-electromagnetic interference capability.
Hot-swap operations should be performed when the system is in "idle" state to avoid data loss during signal transmission.
Regularly check the integrity of connector seals; replace aging or damaged seals promptly to prevent moisture intrusion into the module.
The module is prohibited for underwater use or continuous high-pressure 冲洗 environments; although IP67 resists short-term immersion, long-term humidity may affect isolation performance.
