High Current Adapter for NI myRIO

Overview

The High Current Adapter for NI myRIO allows you drive high power low speed currents

using relays and open drain N-FET otputs trough MXP connector on your myRIO. The

switched signals are connected with screw terminals. For open drains a power supply is

needed.

Key Features:

 Supports 3V…16V power voltage(external power supply required)

 4 Open drain outputs

 Continuous current:3.0A(25°C)/2.2A(85°C)

 Peak output current:4.1A(t<5s)

 4 Standard 3 terminal relay outputs

 Common, Normally Closed, Normally Open

 Relay output max switching voltage:30V

 Rated current:1A

 34-pin female breakout allowing direct access to signal pins

 Uses the myRIO Expansion Port(MXP) connector
