U5841M, U5841G ________________________________
Measured values:
3 x voltage (0
– 10) V
1 x binary input. This input can be configured to voltage
or a dry contact (with open collector transistor
acceptance). Unlike the U0843M (U0843G) model, 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.
Binary input configured for a dry contact or an open-
collector transistor:
Contact resistance for the „switched-on“ state:
< 10 kΩ
Contact resistance for the "switched-off" state:
> 2 MΩ
Excitation voltage: approx. 3 V
Minimum state duration necessary for latching
the state: 1s
Connection:
Pluggable terminal block, maximum wire cross section
1.5 mm
2
. The maximum cable length is 30 m. It is
recommended to use shielded cables.
CAUTION: The inputs are not galvanically isolated!
Recommended calibration interval:
2 years
