Two-channel binary-input counter
This model includes four inputs. Two of them can
function as counters, and all four inputs can function as
binary inputs. Both counter and binary inputs serve to
monitor voltage signals or signals coming from a dry
contact. The binary input changes are registered
immediately, irrespectively of the recording interval
setting. To safe record the input status, the signal must
be present for at least 1 s. Binary inputs can capture
connected/disconnected voltage status. The counter
states are recorded according to the set
Record interval.
Input signals are connected to a pluggable terminal
block. The device’s ingress protection is IP 20. Due to
its low ingress protection the device is not suitable for
using in dusty rooms or rooms exposed to water
ingress. The maximum length of the input wires should
not exceed 30 m. It is recommended to use shielded
cables. The battery in the device cannot be charged.
Optional input configurations:
•
2 x c 2 x binary input
•
1 x c 3 x binary input
•
4 x binary input
Connection:
The procedure for connecting the wires to the terminals
can be found in
Annex 4 .
