![]() ![]() This is sub-optimal in terms of noise immunity since the threshold remains unchanged. Operation without series resistor is also allowed. The recommended resistor values are 4.7 kΩ for 12V signaling and 10 kΩ for 24V signaling. To obtain the best noise immunity with 12V and 24V signaling, it is recommended to insert a series resistor in the circuit. 12V and 24V signaling voltages are also accepted. ![]() The +5V and +12V power supplies available on SYSTEM IO connectors are used for connecting the inputs. Such drivers require a user-supplied power source. Potential free contact, solid-state relay, or opto-couplers.The following drivers are compatible with the isolated current-sense inputs: The state of the port is reported through the InputState MultiCam parameter. Guaranteed 'LOW' input state when unconnected.Accepts forward and reverse input voltage up to 30 V without damage.Polarized input, protected in case of polarity reversal.Current limitation at 5 mA for any input voltage up to 30 V.Minimum high-level input voltage: 1.9 V (over 0° ~70☌ temperature range).Maximum low-level input voltage: 1.5 V (over 0° ~70☌ temperature range).Input voltage threshold: 1.65 V, adjustable using an external resistor.Input current threshold: 1 mA, not adjustable.The isolated current-sense input ports have the following characteristics: Isolated current-sense inputs (simplified schematic) ![]()
