For 24 volt DC input modules, an internal 24 volt power connection is provided on the terminal
board to supply a limited number of input devices. Also, a 24 volt DC output is available on the
power supply module’s terminal board to supply a limited number of output devices.
Terminal Block Quick Connect Installation for 16-Point Discrete Modules
The Terminal Block Quick Connect (TBQC) Assembly is an option for certain Series 90-30
discrete I/O modules. See Appendix H for more information.
Ŷ
Remove standard terminal board from module.
Ŷ
Install TBQC faceplate (it has a 24-pin connector).
Ŷ
Mount the TBQC terminal block. It has a 24-pin connector and a terminal strip, and mounts
on a standard 35 mm DIN-rail.
Ŷ
Connect a TBQC cable between the TBQC faceplate connector on the module and the
connector on the TBQC terminal block.
Ŷ
Wire I/O devices to the terminal block.
Installation of 32-Point Discrete, 50-Pin Connector Modules
These 50-Pin modules are an older design and are not generally used on new systems, unless to
fulfill standardization requirements. They are mainly used as replacements for existing
installations. For new installations, we recommend the dual 24-pin connector style because they
have additional features not found on the older modules (LED indicators, TBQC), and it is much
easier to fabricate custom-length cables for them. Installation information is provided here for the
convenience of those still using these modules.
Using Weidmuller #912263 Terminal Block
Note: The TBQC is not available for these modules, but you may purchase a Weidmuller #912263
from your electronics distributor for this application.
Ŷ
Mount the Weidmuller#912263 terminal block. It has a 50-pin connector and a terminal strip,
and mounts on a standard 35 mm DIN-rail.
Ŷ
Connect an IC693CBL306/307 cable between the module’s faceplate connector and the
connector on the Weidmuller terminal block. See Chapter 10 for cable data.
Ŷ
Wire I/O devices to the terminal block. See the
Series 90-30 PLC I/O Module Specifications
