Optional Interface Capabilities
The analyzer has optional interface capabilities for up to three additional
gas sensors. One extra digital input is also available (example, for stream
switching applications). These interfaces are located on the Micro-
Interface board.
Gas Sensor Interface Options
Gas sensor interface options include:
• 4–20 mA inputs.
• Half-bridge type sensors.
• For other types, contact AMETEK.
For gas sensor wiring details, refer to the “Analyzer Customer
Connections” drawing, part of the Final “As-Built” drawings included in
the “Supplemental Information” section of this manual.
Digital Input Options
One application for this interface is for operation with a flow switch. The
contact can be non-isolated or isolated (J106, Micro-Interface board). In
non-isolated configuration, the contact is energized from the board (15
V
DC
). In isolated configuration, the contact is energized from an external
source (15 V to 24 V
DC
).
For digital input wiring details, refer to the “Analyzer Customer
Connections” drawing, part of the Final “As-Built” drawings in the ana-
lyzer Documentation Package.
