About the Modules 19
•
Autobaud (will match baud of existing devices on the network)
•
Sequential auto addressing
The 1734-OV2E, 1734-OV4E, and 1734-OV8E modules are protected sink
output modules protected to 1 A. 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-OV2E, 1734-OV4E, and 1734-OV8E
modules feature the following (note that 1734-OV2E, 1734-OV4E, and
1734-OV8E modules have no wire-off indication):
•
Output diagnostics (short circuit and reporting bits per channel)
•
Current limited outputs
•
Autobaud (will match baud of existing devices on the network)
•
Sequential auto addressing
T
he 1734-OA2 and 1734-OA4 ac output modules have sourcing outputs,
which source a voltage of up to 0.75 A per channel. The outputs are not
isolated from each other. For this module, ac outputs are 120/220V ac
nominal, with a range of 74…264V dc.
The 1734-OA2 and 1734-OA4
modules feature the following:
•
Autobaud (will match baud of existing devices on the network)
•
Sequential auto addressing
Relay Output Modules
Two versions of relay modules are:
•
1734-OW2, 1734-OW4 relay module.
•
1734-OX2 relay module.
The 1734-OW2 and 1734-OW4 relay outputs are Type A (Normally Open),
the 1734-OX2 relay outputs are Type 2 Form C. Both modules’ outputs sink or
source a current with respect to power or return. Contact outputs are isolated
from each other. Each output is rated 5…240V rms at 2 A (current is load
dependant). Features include:
•
Autobaud (will match baud of existing devices on the network).
•
Sequential auto addressing.
