Current monitoring module for
HD series solid state relays
Current monitoring HD D0340I
Dimensions of HD series relay with the current monitoringProduct description:
The HD D0340I current monitoring module is a
supplement to the HD solid state series, and permits
monitoring and diagnosis of one or more loads
(maximum five loads).
It makes it possible to detect power failure,
temporary or permanent no-load as well as a short
circuit of the relay.
The module uses a current converter permanently
to measure the load current, and compares this with
the nominal value.
The nominal value can be set either using the Teach
key on the front of the module or an external digital
Teach input (see setting sequence diagram).
A current -16% lower than the nominal value (0.84
x nominal value) indicates that there is a temporary
no-load condition.
If the module detects a fault, the diagnostic output
is activated and the fault type is displayed by the 3
LEDs on the front panel. These LEDs also display
all other statuses.
