Single-Function I/O Boards
North Atlantic Industries (NAI)
NAI offers, and continues to support, primary or single-function I/O boards designed for a specific, single-purpose application. Based on the specialized application itself, from the interface connectors through the motherboard, to the specific function, these boards typically address I/O function integration challenges requiring higher current capacity, layout, and/or grounding requirements. They are specifically designed for rugged defense, industrial, and commercial applications.

P104 LVDT/RVDT Measurement Board
73LD4
-
NAI’s 73LD4 is a PC104-compliant LVDT/RVDT Measurement Board with six separate transformer-isolated channels. The channels can incorporate up to six programmable LVDT/RVDT-to-Digital Tracking Converters in a stack-through module. Each channel is programmable for 2-, 3-, or 4-wire inputs that automatically range between 2.0 volts and 28 volts, so there is no need to purchase multiple boards set for specific inputs. Operating frequency between 360 Hz and 10 kHz can be specified. Each channel also produces differential incremental encoder (A & B) outputs with programmable resolution and a zero-degree marker pulse.

VME Programmable Resistor Board
6906
Programmable Resistor Module
NAI’s 6906 is a single-slot, 6U VME Programmable Resistor Board that can incorporate up to six isolated programmable resistor output channels that simulate resistive transducers (e.g., thermocouple, TAT probe, etc.) and always deliver a true resistor output. This programmable resistor is designed to accommodate multiple resistor values or mixed configurations (different channels with different values) up to a total of six channels.

P104 Synchro/Resolver Simulation Board
73DS2
Simulator
NAI’s 73DS2 is a PC104-compatible Synchro/Resolver Simulation Board with three isolated channels. These channels can incorporate up to three Digital-to-Synchro/Resolver Converters with 1.2 VA drive capability in a stack-through module. With galvanic isolation, one of the outputs can be grounded without affecting performance.

P104 Synchro/Resolver Measurement Board
73SD4
-
NAI’s 73SD4 is a DSP-based, PC104-compliant Synchro/Resolver Measurement Board with six separate, isolated channels. These channels can incorporate up to six Synchro/Resolver-to-Digital Tracking Converters in a stack-through module. Each channel also produces differential incremental encoder (A & B) outputs (with programmable resolution) and a zero-degree marker pulse. Commutation outputs are available for 4-, 6-, or 8-pole brushless DC motors that eliminate the need for Hall Effect sensors, thereby reducing both processor time and bus traffic.

VME PWM Servo Motor Driver
64PW3
-
NAI’s 64PW3 is a 6U VME Servo Motor Driver/Amplifier Board featuring a dual, four-quadrant, bi-directional, PWM servo amplifier. Specifically targeted for DC servo motor applications, this board has an amplified power stage that uses a Pulse Width Modulation (PWM) control signal to provide motor control for both brush and brushless motors. Each motor drive accepts a 65 VDC power input and provides a 5 Amp maximum continuous current output (8.5 Amp peak).

3U cPCI Synchro/Resolver Simulation Board
75DS2
Simulator
NAI’s 75DS2 is a Synchro/Resolver Simulation Board with four independent, isolated channels. These channels can incorporate up to four Digital-to-Synchro/Resolver Simulation Converters with 1.5, 2.2, or 3 VA drive capability, or either two or four Digital-to-LVDT/RVDT Simulation Converters. One of the outputs on each channel can be grounded without affecting performance.
