Number of channels per module | 8 | |
Distribution of channels into groups | 1 group of 8 channels | |
Connections of the channels I0- to I7- | Terminals 1.0 to 1.7 | |
Connections of the channels I0+ to I7+ | Terminals 2.0 to 2.3 | |
Input type | Bipolar (not with current or Pt100/Pt1000/Ni1000) | |
Galvanic isolation | Against internal supply and other modules | |
Configurability | 0…10 V, -10…+10 V, 0/4…20 mA, Pt100/1000, Ni1000 (each input can be configured individually) | |
Channel input resistance | Voltage: > 100 kΩ, current: ca. 330 Ω | |
Time constant of the input filter | Voltage: 100 µs, current: 100 µs | |
Indication of the input signals | One LED per channel | |
Conversion cycle | 2 ms (for 8 inputs + 8 outputs), with Pt/Ni… 1 s | |
Resolution | Range 0…10 V: 12 bits Range -10…+10 V: 12 bits + sign Range 0…20 mA: 12 bits Range 4…20 mA: 12 bits |
|
Conversion error of the analog values caused by non-linearity, adjustment error at factory and resolution within the normal range | Typ. | ± 0.5 % of full scale at 25°C |
Max. | ± 1 % of full scale (all ranges) at 0…60 °C or EMC disturbance |
|
Relationship between input signal and hex code | See table, Measuring Ranges | |
Unused voltage inputs | Are configured as “unused” | |
Unused current inputs | Have a low resistance, can be left open-circuited | |
Input data length | 16 bytes | |
Overvoltage protection | Yes |
