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. Unlike the U0843M
(U0843G) model,
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 has not a protection against the
ingress of water or dust. Do not use device at places
where such conditions can be expected. The maximum
length of the input wires should not exceed 30 m. It is
recommended to use shielded cables.
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 .
