I/O Terminal Block Terminal Assignments
The diagrams below show terminal assignments for the different types of I/O Terminal Block that
can be used with the module. The Terminal Block with Box Terminals has 25 terminals for each
module. Each accommodates one AWG #14 (avg 2.1mm2
cross section) to AWG #22 (avg
0.36mm2
cross section) wire, or two wires up to AWG #18 (avg. 0.86mm2
cross section). When an
external jumper is used, single-wire capacity is reduced from AWG #14 (2.10mm2
) to AWG #16
(1.32mm2
).
The I/O Terminal Block with Barrier Terminals has 18 terminals per module. Each terminal can
accommodate one or two wires up to AWG #14 (avg 2.1mm2
cross section).
The I/O Terminal Block with Connectors has one 20-pin male connector per modulePower Sources
No loop power is required for this module. The excitation current for the RTDs is provided by the
module, which automatically matches the excitation current to each configured RTD type.
LED
A single indicator shows module status:
ON: normal operation
Intermittent flashing: module fault
OFF: loss of backplane power or fatal fault
