Notes:
2. This model comprises a total of 12 inputs. Input functionality can be adapted as follows:
12 inputs may be used as digital inputs. They may be wired, in a group, and set to either
npn or pnp via a single jumper.
In addition, according to jumper settings and appropriate wiring:
- Inputs 10 and 11 can function as either digital or analog inputs.
- Inputs 0, 2, and 4 can function as high-speed counters, as part of a shaft-encoder,
or as normal digital inputs.
- Inputs 1, 3, and 5 can function as either counter reset, as part of a shaft-encoder,
or as normal digital inputs.
- If inputs 0, 2, 4 are set as high-speed counters (without reset), inputs 1, 3, 5 can function as
normal digital inputs.
3. pnp/npn maximum frequency is at 24VDC.

Analog Inputs
Number of inputs 2, according to wiring as described above in Note 2
Input type Multi-range inputs: 0-10V, 0-20mA, 4-20mA
Input range 0-20mA, 4-20mA 0-10VDC
Input impedance 243Ω >150KΩ
Maximum input rating 25mA, 6V 15V
Galvanic isolation None
Conversion method Successive approximation
Resolution (except 4-20mA) 10-bit (1024 units)
Resolution (at 4-20mA) 204 to 1023 (820 units)
Conversion time One configured input is updated per scan. See Note 4
Precision 0.9%
Status indication Yes – if an analog input deviates above the permissible range, its
value will be 1024.
Notes:
4. For example, if 2 inputs are configured as analog, it takes 2 scans to update all analog values.
