I/O Extension Card with Encoder Inputs (VW3A58202U)
This card includes two 24 Vdc logic inputs, one 24 Vdc open collector logic
output, one 0 to 20 mA X-Y configurable analog output, and A+, A–, B+, B–
inputs which may be used for speed correction with an i nc rem en tal encoder
or with an inductive or photoelectric sensor.
The figure to the left shows the location of the terminals for this I/O c ard, while
the tables below describe the terminals. Se e page 50 for a summary of
configurable I/O functions.

Available internal supplies
Protected against short circuits and overloads
1 output +10 V ± 1%, Is = 10 mA maximum
1 output -10 V ±1%, Is = 10 mA maximum
1 output +24 V (20 V min., 30 V max.), Is = 200 mA maximum◆
Logic Inputs LI
2 reassignable logic inputs. Impedance = 3.5 kΩ. Compatible with level 1 PLCs
according to IEC 60065A-68. Maximum shielded cable length: 330 ft (100 m).
Supply: +24 Vac (11 V min., 30 V max.)
State 0 if < 5 V, state 1 if > 11 V.
The logic inputs are sampled every 2 ms, maximum.
Logic Output LO
1 reassignable open collector logic output, compatible with level 1 PLCs according to
IEC 60065A-68.
Supply: +24 V (12 V min., 30 V max.),
maximum current = 20 mA with internal source or 200 mA with external source.
The logic output is updated every 2 ms, maximum.
Analog Output AO
1 reassignable 0 - 20 mA analog output, (x - y configurable).
Maximum load impedance = 500 Ω.
Resolution: 0.04 mA (9 bits)
Linearity: ± 0.1 mA
Accuracy: ± 0.2 mA
The analog output is updated every 2 ms, maximum.
Logic Inputs A, A-, B, B-
For incremental encoder (TTL, line driver, push pull) or open collector type
(NPN detector, three-wire inductive, or photoelectric sensor).
Nominal voltage: 24 Vdc (19.2 to 30 V).
Input impedance: 785 Ω ±10%.
Maximum signal frequency: 33 kHz with motor operating at drive controller high
speed setting (HSP).
It is preferable to use an external 24 V external supply for the incremental encoder.
◆The 200 mA is the sum of the current supplied by the +24 on the control board and
the +24 on the I/O extension card.
