Expanding Inputs/Outputs You can add expansion units to all GFX types with an expansion I/O socket
to increase the number of inputs and outputs:
Local Expansion
Local expansion units are fitted directly next to the processor unit with the
expansion I/O socket connection.

Processor Unit I/O Modules Description
1760-LDF
1760-LDFA
1760-LDFC
1760-LDFCA 1760-IA12XOW6I 12 AC inputs, 6 relay outputs
1760-IB12XOB8
12
(1)
DC inputs, 8 transistor outputs
(1) Four of the digital dc inputs can alternately be used as 0 to 10V dc analog inputs. These inputs can be used as
either digital or analog, not both. For example you could use 4 analog inputs plus 8 digital inputs.
1760-IB12XOW6I 12 DC inputs, 6 isolated relay outputs
1760-OW2 2 relay outputs
ATTENTION
The following electrical separation is implemented between
the processor unit of the GFX device and the expansion
unit (separation always in local connection of expansion
unit)
• Simple isolation 400V ac (+10%)
• Safe isolation 240V ac (+10%)
Units may be destroyed if the value 400V ac +10% is
exceeded, and may cause the malfunction of the entire
system or machine.
IMPORTANT
GFX processor units and expansion units can be fed by
different DC power supplies.
