AR006091
________________________________________
Measured values:
3x current input,
1 x binary input. This input can be configured to accept
voltage signals or a voltage-free contact (as e.g.
an open-collector transistor). Unlike the
AR006092
model, this input can capture connected/disconnected
voltage status.
Range and input levels:
Current input:
Range: (0 to 20) mA DC
Accuracy: ± 20 uA
Resolution: better than 1 uA
Input resistance: approx. 100 Ω
Minimum current: 0 mA (open circuit)
Maximum current: limited to approx. 40 mA
Binary input configured for voltage measurements:
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 voltage-free 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 mode:
Split connection 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 separated!
Recommended calibration interval:
2 years
