18 About the Modules
This table lists the 1734D POINTBlock modules.
Input Modules
For input modules, dc inputs are 24V dc nominal, with an input range of
10…28.8V dc, and are offered with 2, 4,or 8 sinking style inputs, or 2, 4, or 8
sourcing style inputs. The 1734-IB2, 1734-IB4, 1734-IB4D, and 1734-IB8
input modules are sinking modules. The 1734-IV2, 1734-IV4, and 1734-IV8
modules are sourcing input modules.
For input modules, ac inputs are 120V ac nominal with an input range of
85…132V ac, or 220V ac nominal with an input range of 159…264V ac, with
sinking inputs.
Features of the all input modules include the following:
•
Autobaud (will match baud of existing devices on the network)
•
Selectable input filter times (0…65 ms with 1 ms default)
•
Sequential auto addressing
Output Modules
T
he 1734-OB2, 1734-OB4, 1734-OB8, 1734-OB2E, 1734-OB4E, and
1734-OB8E dc output modules have current limited sourcing outputs, which
source a positive voltage of up to 1 A with respect to their dc return per
channel. The 1734-OB2EP sources a positive voltage of up to 2 A with respect
to its dc return per channel. The outputs are not isolated from each other. For
these modules, dc outputs are 24V dc nominal, with a range of 10…28.8V dc.
A number of output diagnostic features are incorporated to assist in
troubleshooting
.
The 1734-OB2E, 1734-OB2EP, 1734-OB4E, and
1734-OB8E modules feature the following:
•
Output diagnostics (short circuit and wire-off indication and reporting
bits per channel)
•
Current limited outputs
