U5841 _________________________________________
Measured values:
3 x voltage input (0 - 10) V
1 x binary input. This input can be configured to voltage
or a dry contact (with open collector transistor
acceptance).
This input can capture
connected/disconnected voltage status.
Range and input levels:
Voltage inputs:
Range: (0 to 10) V DC
Accuracy: ± 10 mV
Input resistance: approx. 130 k
Ω
Binary input configured for voltage signal:
Input voltage for the „L“ level: < 0.8 V
(*)
Input voltage for the „H“ level: > 2 V
Minimum applicable voltage: 0 V
Maximum applicable voltage: +30 V DC
(*)
When the input is disconnected, the device will
measure the „L“ level.
