ABB M10 Series User Manual

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).
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.

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 outputs which are
listed in technical data section in case a ex-
ternal load is connected.
Spark suppression is necessary for con-
necting contactor (except AF type) to en-
sure a reasonable service life of output re-
lays. (Fig 13)
