About the Modules 3
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.
Analog Modules
The 1734 analog modules consist of input modules (1734-IE2C and 1734-
IE2V) and output modules (1734-OE2C and 1734-OE2V). Each module has
two single-ended, non-isolated channels.
The features of the analog modules depend on the type of analog module: input
or output. These are features common to both input and output modules.
•
Data - The current input and output modules operate in unipolar mode
only. Voltage input and output modules operate in unipolar or bipolar
modes. Data returned from the module is scaled by the user to any 16 bit
signed integer
(–32,768...+32,767).
•
Input modules produce 6 bytes of data.
