General Description

The McNab Micromodule Output Board, Catalog #: 62139-M( )P( ), is a member of McNab's modular, solid-state (electronic) micromodules. The device offers high sensitivity with exceptional operational and temperature stability.

Configuration Codes

Generic Part Number

Output Range Parameter (See Below)

Indicates Factory Type Pre-Calibration (Nominal Zero & Span)

No "P"# Indicates 'NOT ORDERED

Application

The Micromodule Output Board may be used in electronic systems where an output analog meter signal is required from given input control signals. The device may also be used in applications where frequency to voltage conversion is the primary consideration.

Notes:

  1. When "P" is ordered, PCA will be factory calibrated to type class nominal ZERO and typical SPAN (+/-3%) FS.

  2. This SYSTEM typically will not read "ZERO" when shaft is at rest.

  3. Customer to calibrate SYSTEM ZERO by "rolling torque" method at dockside or "drag shaft" method at sea and still will not read zero at rest.

  4. 4- Electrical calibration of SPAN is then required to meet full-scale output parameter.

  5. To verify PCA "function," use McNab Field Test Fixture: PN500352.in accordance with McNab Test Procedure: PN52042.
