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.
