Description
Product Description
The Honeywell 05701-A-0512 rack assembly is a modular mounting chassis developed for the Honeywell SIEGER System 57 gas detection platform. This 19-inch half-width rack provides mechanical housing and backplane connectivity for multiple detection control cards, enabling compact installation of multi-channel gas monitoring systems in industrial environments.
Engineered with a rear-wired configuration and a dual-chamber internal layout, the rack separates sensitive electronics from field wiring interfaces. This design improves electromagnetic compatibility and simplifies maintenance procedures. The rack supports up to eight individual single-channel control modules along with a dedicated engineering interface slot, making it suitable for scalable gas detection installations.
Widely used in hazardous industrial facilities, the 05701-A-0512 rack ensures organized module integration, stable signal distribution, and reliable power routing within System 57 detection systems.

Key Design Characteristics
Compact Multi-Channel Integration
The half-width rack structure allows multiple detection channels to be installed in a limited cabinet space, supporting scalable gas monitoring systems.
Rear Field Wiring Architecture
All signal and power wiring connections are located at the rear panel, enabling quick module replacement and reducing disruption to adjacent channels during maintenance.
Dual-Chamber Electromagnetic Protection
The rack separates control electronics from field connection terminals, improving shielding against electromagnetic interference and ensuring stable signal integrity.
System 57 Modular Compatibility
Designed specifically for the System 57 architecture, the rack supports a range of compatible control cards including gas detector input modules and relay interface cards.
Industrial Environmental Tolerance
The rack assembly operates across wide temperature and humidity ranges, supporting reliable installation in demanding industrial control cabinets.
Typical Applications
Oil and gas processing plants requiring continuous monitoring of combustible or toxic gases
Chemical manufacturing facilities implementing centralized gas detection control systems
Power generation stations monitoring hazardous gas presence in turbine halls or fuel handling areas
Industrial safety systems requiring modular gas monitoring infrastructure in control cabinets
FAQ
What modules can be installed in the 05701-A-0512 rack?
The rack supports System 57 single-channel control cards such as gas detector input modules, alarm relay cards, and other compatible System 57 interface modules.
Does the rack include power supply functionality?
The rack itself distributes power through the backplane but relies on external DC power input or compatible power modules within the System 57 configuration.
Can the rack operate with other Honeywell gas detection systems?
No. The 05701-A-0512 is specifically designed for the Honeywell SIEGER System 57 platform and is not interchangeable with other Honeywell detection systems such as Sensepoint or Searchline platforms.
Is field wiring affected when replacing control cards?
No. Because of the rear-wired design, control cards can be removed or replaced from the front without disturbing field wiring connections.
