3.4.2. Parameters
Tab. 3.5: Table of digital and analog input and output parameters
passive
– bipolar SSR switch design
– voltage for supplying load max. 30 V DC, 24 V AC
– switched current typically 300 mAresistance in on state
max. 1 Ω
– protection against current overload in on state
– protection against overvoltage in off state
2 × optically separated
digital output
passive
– passive optical element design
– input voltage 0–2,3 V will be evaluated as log. 0
– input voltage 2–30 V will be evaluated as log. 1
– max. value of input voltage 30 V
2 × optically separated
digital input
active
– current source 4–20 mA
– load resistance max. 250 Ω
– settings accuracy better than 0.1 %
