Curtiss-Wright IP-IDLS40T0-67 / BHAS-LOW40 IndustryPack I/O Module

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.
