The Series 2000 intrinsic safety isolation system from P&F Products was designed to make IS interfacing as convenient as possible.
Some areas of the interfacing system where the more obvious advantages can be seen, include the following:
* Simpler installation and commissioning: Field cables and shields can be landed directly to screw terminals on the rugged mounting board to provide tidy and secure wiring terminations. Loop-disconnect terminals (aka knife-edge) make testing and commissioning faster and easier.
* High signal density: Plug-in modules provide isolation and intrinsic safety interfacing for all types of plant signals. Multiple channels are packed into compact housings and achieve high packing density with high signal integrity.
* Integral signal marshalling facility: The ability to marshall the input/output signals into the groups and quantities related to specific system I/O cards is available through use of the patented cross-wiring option for the termination boards.
* System integration: Use standard system cables to link with the I/O cards of the instrumentation system. Interface adapter cards provide system connectivity to match all types and modularity of I/O equipment.
* Easier maintenance: The fault monitor module provides a composite logic output signal for the modules mounted on a termination board to indicate faults in the field wiring for operators or to initiate control action.
