General Electric IS221PDIAH1B Full-duplex Ethernet port
The GE IS221PDIAH1B is a Mark VIe non-safety discrete input module (PDIA), adapted for turbine control and distributed I/O architectures. It features 32 discrete inputs and redundant communication, ensuring stable acquisition and real-time transmission of switch signals in industrial environments.
Core Performance:
I/O and Electrical Capabilities
Discrete Inputs: 32-channel 24VDC wet contact inputs, compatible with limit switches, pressure switches, and other contact signals. Single-channel rated current is 2A. Supports contact closure/opening status acquisition and is compatible with 22.5-28.6VDC power supply.
Isolation and Certification: 2500Vrms isolation between channels, UL/CE certified, suitable for Class 1 Div 2 hazardous areas, vibration/shock resistant, and fault propagation prevents damage.
Diagnostic Functions: LED status indication for each channel, supports ControlST real-time diagnostics of channel status and link quality, and rapid contact fault location.
Communication and Electrical
Communication Interface: Dual 100M full-duplex Ethernet ports, supporting IONet/Modbus TCP, redundant links ensure continuous data transmission, compatible with Mark VIe distributed I/O architecture.
Power Supply: 22.5-28.6VDC, overvoltage/reverse connection protection, operating temperature -30℃ to 65℃, suitable for harsh industrial environments.
Management and Maintenance: Supports hot-swapping; failure does not affect other channels, suitable for the continuous operation requirements of turbine control.
Compatible Terminal Blocks: IS200STCIH1A/2A, IS200TBCIH2C/H4C, IS400STCIH1A/2A/8A, etc., connected via DC-37 pin connectors for flexible installation.
