The IS200VAICH1DAB is a VME bus Analog Input/Output Board (VAIC) designed for the GE Mark VI control system. It supports 20-channel analog input acquisition and 4-channel analog output control, integrating A/D conversion, D/A conversion, signal conditioning, and analog multiplexers (MUX). Compatible with both Simplex and Triple Modular Redundancy (TMR) architectures, it is widely used for high-precision process monitoring and closed-loop control in industrial applications such as gas/steam turbines, petrochemicals, and power generation. Featuring high reliability, strong anti-interference performance, and easy maintenance, it provides a flexible and stable analog signal interface for the Mark VI system.
Specification Parameters
Model: IS200VAICH1DAB (VAIC for functional abbreviation)System affiliation: GE Mark VI control system, VME bus moduleInput channels: 20 channels in total, including 16 channels compatible with ±10V DC/±5V DC/4-20mA, and 4 channels compatible with 4-20mA/±1mAOutput channels: 4 channels in total, including 2 channels for 0-20mA/0-200mA signals, and 2 channels for 0-20mA signals (configurable as 4-20mA standard signals)Conversion accuracy: Equipped with 16-bit A/D and D/A converters, featuring an input accuracy of ±0.1% FS and an output accuracy of ±0.2% FSRedundancy support: Compatible with Simplex and TMR architectures; in TMR mode, signals are fanned out to 3 VAIC modules with automatic switchover upon hardware failureCommunication interface: Compatible with the VME bus of Mark VI system, supporting high-speed data interaction via system backplanePower consumption: ≤31mW; adopts Surface Mount Technology (SMT), realizing low power consumption and vibration resistanceDiagnostic function: On-board LED indicators for real-time display of channel status, power supply, communication and fault alarmsPhysical characteristics: Compliant with VME standard slot size, equipped with J3/J4 latch connectors, suitable for industrial cabinet installation
Key Features
High-precision measurement: 16-bit resolution and ±0.1% FS input accuracy, suitable for high-precision monitoring requirements in industrial field applications, such as the acquisition of key parameters including turbine speed and steam pressure.
High-reliability design: Adopts industrial-grade components, SMT process and redundant architecture; withstands a wide temperature range of -40℃~+85℃ and 5-95% RH (non-condensing) environment, enabling long-term stable operation.
Flexible configuration capability: Input and output channels support software configuration of signal types and ranges without the need for hardware jumpers; compatible with different sensors and actuators, reducing the complexity of system integration.
Convenient diagnostic maintenance: LED indicators provide real-time feedback on channel status, facilitating online fault location; the modular design allows hot swapping (subject to compliance with system specifications), minimizing downtime for maintenance.
