This module serves as a dedicated I/O component for the AC 800 PEC control platform, and is also a core supporting module of static excitation systems. Designed with a modular architecture and distributed control logic, it supports redundant subsystem configurations, meeting the high reliability requirements of mission-critical industrial environments such as power, heavy industry, and process automation.

Circulation Characteristics & Quality Assurance

Supply status: Predominantly distributed as brand-new, original, factory-sealed modules.

Inventory: Multiple automation suppliers—especially in Xiamen and other industrial hubs—indicate in-stock availability with MOQ = 1 piece, suitable for urgent on-site maintenance.

Warranty: Most suppliers provide a one-year warranty and global delivery, ensuring rapid response for equipment replacement and system restoration.

Installation Features

Industrial universal modular design, supporting standard DIN-rail mounting

Direct plug-in compatibility with series terminal baseplates, no customized accessories required

Flexible installation:

For local CPU racks in AC 800 PEC systems

For distributed substations through FBP (Fieldbus Plug) extension

Key Technical Parameters

1. Power Supply & Environmental Adaptation

Standard power input: 24 VDC, widely used in industrial control systems

Optional support for 110–240 VAC wide-voltage input (depending on configuration)

Operating temperature: –20 °C to +60 °C, suitable for fluctuating on-site climates

Protection rating: IP20, requiring installation within a control cabinet

Designed to remain protected from dust, condensation, and corrosive environments when installed properly

2. I/O and Communication Capability

Supports both digital and analog input/output channels

Suitable for sensor data acquisition and actuator command output

Compatible with multiple wiring topologies: 1-wire, 2-wire, 3-wire baseboard configurations

High wiring flexibility, adaptable to diverse field sensors, push buttons, limit switches, and transducers

Communication support includes:

Ethernet

Profibus

Modbus

Enables transparent data exchange and seamless integration with factory-level supervisory systems (SCADA, DCS, energy management, etc.)

3. Expansion Capability

When used as part of a distributed PEC substation, the system can expand up to:

7 additional I/O modulesAmong them, up to 4 analog modules

This allows flexible scaling of signal capacity according to plant size, device count, or process complexity.
