R. Stahl, Inc.
The Best Solution to Hazardous Location Instrumentation

INTRINSPAK® Widely copied, never duplicated:

• Short circuit proof, allows live maintenance.
  
• Snap-on mounting & grounding, attaches to 35mm DIN rail, the quickest, safest installation method available.
  
• The lowest resistance available, allows the most power thru the barrier for driving field circuits.
  
• The lowest leak current available; < 1µA in critical applications, provides the greatest degree of electrical isolation.
  
• The smallest intrinsic safety barrier.
  160ma replaceable fuses, services all models.
• INTRINSPAK® intrinsic safety barriers.
  The widest selection in the industry.

Advantages:

IS-1 Network topology allows I/O about your facility.
Buss, tree & star configurations are possible using copper and fiberoptic technology.
Distributing IS-1 moves the I/O closer to your field devices saving labor and material in installation.
Networked I/O saves 30-40% cost over conventional hard wiring.
Networking solutions include Profibus, Fieldbus Foundation, ControlNet and Modbus. Other solutions available on request.
Input low level signals like TC's & RTD's directly.

Standard:

Installation can be safe area, Div.1/Zone1, Div.2/ Zone2.
All signals are monitored for short/open circuit, full HART support, fault status configurable.
Modules are hot swappable, can be mixed IS and non-IS field circuits, complete system redundancy.
Diagnostic information indicates status of the CPU & I/O as well as any faults on the field wiring.
Highest point density on the I/O modules provide a cost effective solution.
