Logical I/O blocks

Slope [Slpe] and Intercept [Icpt]

CM110664en_07 279 | 351

Solution examples:

Zener diode Voltage divider

Active setpoint adjuster BSG61

(Datasheet CE1N1992)

Slope must be adapted to 0...5 V

(0.01 -> 0.005)

Precision resistance, e.g., VISHAI

MBB/SMA 0207

Switch position 1 (Setpoint limit

control) Setpoint 100%

[Icpt] and [Slpe] for BT devices

Note for all U10 inputs

The physical inputs are designed for 0 -10V with narrow high and low tolerance limits. If a value falls

outside this range, the input transmits an error signal. However, provided it is established that the

peripheral devices are in order, an error signal can be prevented by using a transient voltage suppressor

(10 V Zener diode and two resistors). A faulty response from the analog input signal supplied cannot

subsequently be detected in the automation station.
