Technical Specifications Item SM35-J-R20 PLC with Flat panel, Color touch display 3.5’’ SM43-J-R20 PLC with Flat panel, Color touch display 4.3’’ SM70-J-R20 PLC with Flat panel, Color touch display 7’’ Power SupplyItem SM35-J-R20 SM43-J-R20 SM70-J-R20 Input voltage Permissible range Max. current consumption npn inputs pnp inputs Notes: 20.4VDC to 28.8VDC with less than 10% ripple See Note 1 1. To calculate the actual power consumption, subtract the current for each unused element from the maximum current consumption value according to the values below: Digital Inputs Number of inputs Input type Galvanic isolation Nominal input voltage Input voltage pnp (source) Input current Input impedance Response time Input cable length Normal digital input High Speed Input 12. See Note 2 See Note 2 None 24VDC 10ms typical, when used as normal digital inputs Up to 100 meters Up to 50 meters, shielded, see Frequency table below

High speed inputs Specifications below apply when wired as HSC/shaft-encoder. Frequency (max)_See Note 3 Input type Input range Input impedance Maximum input rating Galvanic isolation Conversion method Resolution (except 4-20mA) Resolution (at 4-20mA) Conversion time Precision Status indication Successive approximation 10-bit (1024 units) One configured input is updated per scan. See Note 4 0.9% Yes - if an analog input deviates above the permissible range, its value will be 1024. 4. For example, if 2 inputs are configured as analog, it takes 2 scans to update all analog values.
