Terminal block X4 Digital output relays

Two sets of output relays are available from
X4:1~5 in M102. Relay 1 (GR1) provides one pair
of NC and NO outputs which is configurable as
different functions, e.g. trip, alarm indication.
Relay 2 (GR2)provides one set of NC output
which is also configurable.
Only relay 1 is available in M101 version.
Digital output relays are indicated in typical
wiring diagram Fig (13).

Terminal block X4 Contactor control relays

Three sets of contactor control relays are avail-
able in M102, i.e. Relay A (CCA), relay B (CCB)
and relay C (CCC). Three relays are pre-config-
ured to respond to different motor starter con-
trol logic. For example, in a direct on line
(DOL) starter control, CCA is dedicated to be
used as open and close the contactor.
CCA and CCB are internally interlocked through
hard-wired.
Only relay CCA and CCB are available in M101.

Wiring Tip:
Take note of the rating operational
current and load type of digital out-
puts which are listed in technical data
section in case a external load is con-
nected.
Spark suppression is necessary for connect-
ing contactor (except AF type) to ensure a
reasonable service life of output relays.
GR1 & GR2 contact status may change accord-
ing to the assigned function. For example, if
GR1 is assigned as "trip", NO contact close un-
der healthy condition and open under trip.
contact status resets during power loss.

Take note of the rating operational current
and load type of digital outputs which are
listed in technical data section in case a ex-
ternal load is connected.

necting contactor (except AF type) to en-
sure a reasonable service life of output re-
lays. (Fig 13)
