VXi VT1529A/B 사용자 설명서

The VT1422A is comprised of the main A/D module and optionally, a 
Connector or Terminal Module. The Option 001 Connector Module provides 
sixteen RJ-45 jacks to allow easy connection of the VT1422A to Remote 
Signal Conditioning Units (RSCUs) like the VT1529A/B Remote Strain 
Conditioning Unit. Optional conventional terminal modules include a 
Terminal Module with screw-clamped terminal blocks (Option 011) and 
another with spring-clamped terminal blocks (Option 013).

The Spring Terminal Module and Screw Terminal Module provide:

•

Terminal connections to field wiring.

-- Allows a mix of direct field wiring with some connections to 

Remote Signal Conditioning Units

•

Strain relief for the wiring bundle.

•

Reference junction temperature sensing for thermocouple 

measurements.

•

Ground-to-Guard connections for each channel.

The RJ-45 Connector Module provides:

•

Easy mass terminated plug-in connection to Remote Signal 

Conditioning Units.

•

Allows some direct analog or digital field wiring to be connected to 

RJ-45 modular plugs that are then plugged into the Connector Module.

•

Note: Since the RJ-45 Connector Module was designed for connection 

to RSCUs, it doesn’t provide an on-board isothermal reference 
thermistor or connection to the VT1422A’s on-board current source. 
This means that the RJ-45 Terminal Module is not suitable for direct 
connection to thermocouples.

Each SCP includes a set of labels to map that SCP's channels to the Terminal 
Module's terminal blocks. See “Installing SCPs: Step 4, Labeling” on 
page 28

Figures 2-4 through 2-6 show the layout and feature location of the Terminal 
Modules available for the VT1422A.
