Woodward 9907-162 Digital Input Module for 505/505E Turbine Control System

Product Description

The Woodward 9907-162 is a high-reliability 8-channel digital input module specifically designed for integration with Woodward 505/505E digital turbine governors and control systems. Engineered for industrial turbine applications, this module accepts 24 VDC dry contact or sourced digital input signals, providing isolated signal acquisition with built-in surge protection and diagnostic capabilities. It features pluggable terminal blocks for easy wiring and maintenance, LED status indicators for each input channel, and seamless communication with the 505/505E main controller via the internal backplane bus. Ideal for gas, steam, and hydro turbine control in power generation, oil & gas, and industrial manufacturing facilities, the 9907-162 ensures accurate and reliable monitoring of turbine status signals (e.g., trip conditions, limit switches, run status) in harsh industrial environments.

Key Functions

The 9907-162 digital input module delivers robust, isolated signal acquisition for turbine control system applications. Key functions include: 8 independent 24 VDC digital input channels (compatible with dry contact or sourced inputs, 18-30 VDC operating range); channel-to-channel isolation (500 VAC) to prevent cross-talk and ground loop issues; built-in surge and transient protection (±2 kV ESD, ±1 kV surge) to safeguard against electrical interference; LED status indicators for each input channel (ON/OFF) and module power/fault status; pluggable screw terminal blocks for tool-free wiring and quick replacement; direct integration with Woodward 505/505E turbine control system backplane; and compliance with industrial EMC and temperature standards for reliable operation in turbine enclosures.

Application Scenarios

The Woodward 9907-162 digital input module is primarily deployed in turbine control systems across critical industrial sectors. In power generation plants, it monitors safety interlock signals (overspeed trip, low oil pressure, vibration alarm), valve position limit switches, and generator breaker status for gas/steam turbine generators. For oil & gas production facilities, it tracks compressor anti-surge valve status, fuel gas pressure switches, and emergency shutdown (ESD) signals in turbine-driven compressor trains. In industrial manufacturing, it is used for monitoring process interlocks, motor run status, and safety limit switches in turbine-driven pumps and fans. The module is also suitable for combined heat and power (CHP) plants and marine turbine applications—all scenarios requiring reliable digital input signal acquisition for turbine control and protection.
