AR006093
________________________________________
Measured values:
2x user configurable binary input for applying voltage or
connecting a voltage-free contact (as e.g. an
open-collector transistor). Unlike the
AR006092
model, this input is able to catch
also the „voltage
applied/not applied“
states.
2 x counting input. This input, like the binary one, can be
configured to accept voltage signals or a voltage-free
contact (as e.g. an open-collector transistor).
These counting inputs can be used as additional two
binary ones.
Input levels:
Binary or counter input configured for voltage
measurements:
Input volta
ge 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 or counter 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 M
Ω
Excitation voltage: approx. 3 V
Minimum state duration necessary for latching
the state: 1s
Counter parameters:
Range: 24 bits (16 777 215), possibility of letting
the counter overflow
Maximum pulse frequency when configuring for:
- voltage input:
max. 5 kHz
- voltage-free contact or open collector transistor:
max. 200 Hz
Further features: relative counter (count of pulses
sensed during the recording interval)
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!
