DCS Introduction

Our Intelligent Remote Redundant Ethernet I/O Expansion Units Are Reliable, Redundant with Hot Swappable I/O, Robust for Rugged Industrial Environments. They Support our eLogger and EZ Data Logger Software

The iDCS-8000 is a distributed modular I/O system which communicates with numerous controllers via different communicating interfaces. The iDCS-8000 provides an easy installation of the I/O modules and process cabling. It is highly modularized and flexible so that I/O modules can be combined to suit many applications including the most known types of signals, digital analog, pulse and HART. The iDCS-8000 can be mounted in many configurations to fit most requirements both in single or fully redundant applications.

The iDCS-8000 is a redundant system designed for harsh environments such as oil refining plants, chemical plants, pharmaceutical manufacturing, and water treatment. Moreover, the iDCS-8000 offers the advantage of easy maintenance because the modules, power, communication and I/O, and termination boards can be easily hot-swapped. Besides, there are many functions built-in in iDCS-8000, like auto configuration, fault detection, dual watchdog, etc.

This video demonstrates the redundancy of the iDCS-8830 system.


The DCS modular I/O System features redundant power modules, redundant controllers and gateways, and 8 IO module slots in 4 redundancy groups.

DCS features



The iDCS-8000 offers cost-effective solutions to practically all needs for a field-device, including basic analog and digital I/O, pulse and HART, as well as high-integrity solutions. It allows for hot-swapping to replace devices without having to shut down the system, and auto configuration so that your last settings automatically configure upon replacement.

DCS features 2


The iDCS-8000 offers availability-improving features such as:

- Hot swap of modules, a faulty I/O module can be replaced on-line without powering the station down and without the rest of the station being affected.
- It ensures that only modules of the right type can be inserted when on-line replace.
- Automatically re-configure to the same parameters when plugging a replaced module.
- Redundancy options in all modules, power, communication, I/O.


DCS features 3

The I/O modules plugged in iDCS-8000 station can be configured into single or redundant operation. Users can easily upgrade I/O security in a same station by adding same module and configuring into redundant operation without any additional wiring.

I/O redundant switching < 1ms

DCS features 4

The iDCS-8000 features quick I/O redundant switching under 1ms.

Up-to-date I/O

DCS features 8

The I/O modules plugged in the iDCS-8000 station will automatically update I/O data to communication module. This feature not only decreases the delay for updating I/O data but also acquires up-to-date I/O data.

Easy Diagnostic

The communication and I/O modules provide several LED indicators to help the user to locally identify status and working properly.

Various Communication Interfaces

The iDCS-8000 provides connectivity to the most popular industry-standard such as Modbus, Profibus, Ethernet/IP, DeviceNet, and CANopen. The various communication interfaces help user to integrate most controllers and PLCs.

Rugged Industrial Environment

Dual watchdog design
The iDCS-8000 series I/O modules provide module watchdog and host watchdog. The module watchdog is a hardware watchdog, and the host watchdog is a software watchdog. The module watchdog is designed to automatically reset the microprocessor when the module hangs. The host watchdog monitors the host controller (PC or PLC). The output of module can go to the safe value state when the host fails. 

DCS features 5
- Wide range operating temperature (-25 °C ~ +75 °C)

Full Software Support

- DCS Utility

DCS features 6

- OPC Servers

OPC is an industrial standard interface based on OLE technology. With the OPC server, I/O modules can be easily integrated to any software that has OPC client capability.

- EZ Data Logger

DCS features 7

EZ Data Logger is a small data logger software. It can be applied to small remote I/O system. With its user-friendly interface, users can quickly and easily build a data logger software without programming.
