84 24V dc 10 Input/6 2A Output Combo Module Cat. No. 1794-IB10XOB6 FLEX I/O and FLEX Integra Product Data
Wiring to a 1794-TB3 or -TB3S Terminal Base
Unit
1. Connect the associated input or output power to the corresponding
terminal on the 34-51 row (C) for each as indicated in the table
below. (Power terminals 34 thru 51 are internally connected
together.)
2. Connect the +24V dc power to terminal 34 on the 34-51 row (C).
3. If continuing power to the next terminal base unit, connect a
jumper from terminal 51 (+24V dc) on this base unit to terminal 34
on the next base unit.
4. Connect the associated input or output return to the corresponding
terminal on the 16-33 row (B) for each as indicated in the table
below. (Returns are internally connected together.)
5. Connect 24V dc return to terminal 16 on the 16-33 row (B).
6. If continuing 24V return to the next terminal base unit, connect a
jumper from terminal 33 (return) on this base unit to terminal 16 on
the next base unit.
7. Connect the individual input and output wiring to numbered
terminals on the 00-15 row (A) as indicated in the table below.
Setting Input Filter Time
(Standard Addressing Mode Only)
(not available when used with the 1794-ASB adapter)
You can select the input filter time (FT) for the input channels
(channels 00 through 09). Select the input filter time by setting the
corresponding bits in the configuration word (word 3) for the module.
For example, to set a filter time of 8ms for a dc input module at
address rack 1, module group 0, set bits 08, 09, and 10 in
configuration word 3 as shown below.
ATTENTION
!
Total current draw through the terminal base
unit is limited to 10A. Separate power
connections may be necessary.
