Core Features
High-Density Power Distribution

A single JPDH board supplies power to 24 I/O modules and 3 Ethernet switches, significantly reducing cabinet space requirements and supporting compact, distributed control system architectures.

Triple Redundant Power Input

The 6-pin J1 input interface supports three independent 28 V DC power feeds, greatly enhancing power supply reliability for critical turbine control applications.

Hazardous-Area Adaptation

Designed to meet the requirements for hazardous and explosion-risk environments, making it suitable for industries such as petrochemical, oil & gas, and natural gas processing.

Daisy-Chain Expansion Capability

Supports multi-board cascading (daisy-chain) connections, allowing flexible expansion of system power capacity for large-scale I/O deployments.

High-Reliability Connectors

Uses Mate-N-Lok standard connectors, rated for 600 V and 13 A, ensuring robust, long-term electrical connections in demanding industrial environments.

Typical Applications

Centralized power distribution for GE Mark VIe gas and steam turbine control systems

Turbine control installations in hazardous areas (petrochemical, oil & gas, natural gas facilities)

Centralized power management nodes for distributed I/O architectures

Critical industrial control cabinets requiring redundant power supply and high-density outputs
