CI853K01 ABB 3BSE018103R1 System 800xA Dual RS-232 Module

CI853K01 Technical Overview

• The CI853K01 functions as a versatile Dual Channel RS-232 CEX-bus interface for AC 800M controllers.
• It enables high-reliability serial integration using COMLI and MODBUS RTU protocols in both Master and Slave modes.
• This module supports Hot Swap technology, allowing for maintenance without interrupting the entire control system's power.
• Engineers should refer to the CI853K01 hardware manual to verify RJ-45 pinout assignments for non-standard serial cabling.
• The unit features G3 conformal coating, making it suitable for harsh environments per ISA 71.04 standards.

Global PLC Spare HUB's Insight

• The CI853K01 is a critical link for legacy instrument integration within the System 800xA ecosystem.
• While modern systems shift toward Ethernet, the CI853K01 remains essential for connecting to older flow meters and protection relays.
• Its ability to operate within High Integrity (HI) controller environments makes it a preferred choice for safety-related monitoring.

Professional FAQ & Procurement Guide

• Question: Can I use both ports on the CI853K01 for different protocols?
• Answer: Yes, both channels are independent, allowing you to run Modbus RTU on one and COMLI on the other simultaneously.
• Question: Does this module require a separate power supply?
• Answer: No, the CI853K01 draws its 24V power directly from the controller's CEX-bus.
• Question: What cable type is recommended for the RJ-45 serial connection?
• Answer: High-quality shielded twisted pair (STP) cabling is required to maintain G3 compliance and minimize electrical noise.
• Question: Is the CI853K01 compatible with Modbus TCP?
• Answer: No, this model is strictly for serial RS-232 (Modbus RTU). For Modbus TCP, you would typically look at the CI867 module.
• Question: How many CI853 units can I install on a single CEX-bus?
• Answer: You can install a maximum of 12 units on a single CEX-bus, depending on the power budget of your controller.

Expert Selection Tips

• Always check the 3BSE018103R1 part number against your existing baseplate to ensure mechanical alignment.
• For offshore applications, verify that the CI853K01 has the specific marine certificate (e.g., DNV-GL) required for your vessel.
• If your application requires redundant serial lines, please note that this module does not support hardware line redundancy natively.
