GETTING STARTED GUIDE
NI REM-11190
Bus Power Module for Remote I/O
This document explains how to connect to the REM-11190.
Note The guidelines in this document are specific to the REM-11190. The other
components in the system might not meet the same safety ratings. Refer to the
documentation for each component in the system to determine the safety and EMC
ratings for the entire system.
Caution Do not operate the REM-11190 in a manner not specified in this
document. Product misuse can result in a hazard. You can compromise the safety
protection built into the product if the product is damaged in any way. If the product
is damaged, return it to NI for repair.

Electromagnetic Compatibility Guidelines
This product was tested and complies with the regulatory requirements and limits for
electromagnetic compatibility (EMC) stated in the product specifications. These requirements
and limits provide reasonable protection against harmful interference when the product is
operated in the intended operational electromagnetic environment.
This product is intended for use in industrial locations. However, harmful interference may
occur in some installations, when the product is connected to a peripheral device or test object,
or if the product is used in residential or commercial areas. To minimize interference with
radio and television reception and prevent unacceptable performance degradation, install and
use this product in strict accordance with the instructions in the product documentation.
Furthermore, any changes or modifications to the product not expressly approved by National
Instruments could void your authority to operate it under your local regulatory rules.
Preparing the Environment
Ensure that the environment in which you are using the REM-11190 meets the following
specifications.
Operating temperature -25 °C to 60 °C
Operating humidity 5% RH to 95% RH, noncondensing
Pollution Degree 2
Maximum altitude 3,000 m
Indoor use only.
Note Refer to the device datasheet on ni.com/manuals for complete specifications.

1. Insert the bus connector for the REM-11190 into the DIN rail.
Note Verify that you are using the red bus connector. The REM-11190 will
not function if you mount it on any other bus connector.
2. Slide the bus connector along the DIN rail until it connects to the preceding bus
connector.
Note A bus connector will not attach to a preceding bus connector with a
mounted module. Remove the preceding module before installing additional
bus connectors.
3. Repeat Steps 2 and 3 for additional bus connectors.
Installing the Module
What to Use
• REM-11190
• Mounted bus connector
What to Do
Complete the following steps to install the REM-11190 on the DIN rail.
REM-11190 Getting Started Guide | © National Instruments | 5
1. Align the REM-11190 over the appropriate bus connector.
Note Verify that the bus connector socket aligns with the socket on the
underside of the module.
2. Press the REM-11190 directly onto the bus connector and DIN rail until it clicks into
place.
Caution Tilting the module when mounting it on the DIN rail will damage the
contacts.
Installing Spring-Terminal Blocks
What to Use
• REM-11190
• Spring-terminal block
What to Do
Align the spring-terminal block over the REM-11190 and press until it clicks into place.

The supply terminals blocks contain internal jumpers. You can use the first connection for
supply and the second connection to forward a potential to the next module.
Caution Connect an 8 A external fuse to the 24 V UL supply to protect against
polarity reversal. The power supply must provide four times the nominal current of
the external fuse. This rating ensures that the fuse trips in the event of an error.
Connection Guidelines
• Make sure that devices you connect to the REM-11190 are compatible with the module
specifications.
• Push the wire into the terminal when using a solid wire or a stranded wire with a ferrule.
• Open the terminal by pressing a screwdriver into the spring lever when using a stranded
wire without a ferrule.
