1 DESCRIPTION
LPC-2.DO4 is a snubberless zero crossing triac digital output module. It can be used in a wide range
of operation.
LED indicates triac output contacts' state. If it is on, the module's connection pins are shorted (refer
to the Table 5).
Module is powered from internal BUS.
NOTE: For proper system configuration and data allocation please refer to LPC Composer software
help menu.

NOTE: Special care must be taken in case of high inductance loads, e.g. Relays or contactors. High
inductance load may cause output fail to close. In that case, use of appropriate snubber is advised.

Dimensions in milimeters.
EXTERNAL SWITCH OR CIRCUIT-BREAKER AND EXTERNAL OVERCURRENT
PROTECTION: The unit is allowed to be connected to installation with
over current protection that has nominal value of 16 A or less.
RECOMMENDATION ON SWITCH OR CIRCUIT-BREAKER PROTECTION:
There should be two poles main switch in the installation in order to
switch off the unit. The switch should meet the requirements of
standard IEC60947 and have a nominal value at least 6 A. The switch
or circuit-breaker should be within easy reach of the operator. It
should be marked as the disconnecting device for the equipment.
All connections, module attachments and assembling must be done
while module is not connected to the main power supply.

Mounting instructions:
1. Switch OFF main power supply.
2. Mount LPC-2.DO4 module to the provided place inside an electrical panel (DIN EN50022-35
rail mounting).
3. Mount other LPC-2 modules (if required). Mount each module to the DIN rail first, then
attach modules together through K1 and K2 connectors.
4. Connect digital output wires according to the connection scheme in Figure 2.
5. Switch ON main power supply.
Dismount in reverse order. For mounting/dismounting modules to/from DIN rail a free space of at
least one module must be left on the DIN rail.
NOTE: LPC-2 main module should be powered separately from other electrical appliance connected
to LPC-2 system. Signal wires must be installed separately from power and high voltage wires in
accordance with general industry electrical installation standard.
