The Curtiss-Wright/Systran BHAS-REED25 is a single-wide IndustryPack (IP) module that provides Form-A dry-reed relay switching for data acquisition and control applications. This ANSI/VITA 4-1995 compliant board integrates 25 relays with 16-bit write/read-back registers, delivering no-wait-state performance for time-critical I/O operations. It connects sensors, actuators, and external devices in industrial environments where reliability and isolation are essential.

## Key Features
• Dry-reed relay switching eliminates contact arcing and electromagnetic interference in sensitive measurement circuits
• No-wait-state register access enables immediate I/O control without pipeline delays
• Normally-open contact configuration suits both switching and isolation applications
• Single-wide form factor optimizes carrier slot utilization
• Mechanical and electrical integration with standard IP Module carriers
## Typical Applications
• Multi-channel relay switching for test and measurement systems
• Sensor and actuator signal routing in automated control systems
• Isolated switching in high-noise industrial environments
• Data acquisition system expansion via modular IP architecture
## Compatibility & Integration
The BHAS-REED25 operates with any ANSI/VITA 4-1995 compliant IndustryPack carrier. When deployed in a Curtiss-Wright VMESC5 five-slot carrier, up to 125 relay contacts fit within a single VME6U backplane slot. Mix with other IP modules to build customized multi-function I/O systems.
