The Curtiss-Wright IP-IDLS40T0-67 / BHAS-LOW40 is a 40-channel high-power low-side driver IndustryPack module engineered for industrial I/O control. This singlewide IP module delivers open-collector driver outputs across 40 channels, with per-channel transient diode protection and board-level emitter commons accessible via 8-pin I/O connectors. It conforms to ANSI/VITA 4-1995 both electrically and mechanically, enabling direct integration into standard IP module carriers.
## Technical Specifications
• **Channel Count:** 40 channels
• **Driver Type:** Low-side (Open-Collector) Drivers
• **Power Capability:** High Power
• **Output Configuration:** 8 channels per byte-lane
• **Form Factor:** Singlewide IP Module
• **Standards Compliance:** ANSI/VITA 4-1995 (electrical and mechanical)
## Key Features
• Per-channel transient diode cathode commons routed to I/O connector
• Board-level emitter commons accessible via 8-pin I/O connectors
• Open-collector topology suitable for high-current switching applications
• Scalable architecture—stack multiple modules in quad-IP carriers for expanded channel density
## Typical Applications
• Industrial relay and solenoid control
• Process automation and machinery control
• Data acquisition systems requiring low-side switching
• Discrete I/O control in distributed industrial systems
## Compatibility & Integration
The module integrates into any standard four-module IP carrier. A single quad-IP slot yields up to 160 channels of low-side driver capability on a single computer backplane connection. Mix with other IP modules to build customized I/O solutions without redesign.
