DESCRIPTION
● Three-phase delta-star motor control,
● current decrease during high power
motor start,
● device mode optical signalling (LED
red),
● supply voltage optical signalling (LED
green),
● trigger by applying supply voltage,
● starting time adjustment (STAR sys-
tem),
● interval time adjustment of STAR to
DELTA switching,
● two independent relay outputs, dry
contact 2 x NO/NC of 10 A capacity,
● mounting in distribution boards (TH35
rail).
The PCM-08 time relay is used to
control the STAR-DELTA contactor
switch. It is applied in three-phase mo-
tor control systems. This control me-
thod allows to reduce starting currents
in case of motor units with a capacity
of more than 4-5 kW and additionally it
provides safety. The PCM-08 device has
two independent relay outputs activated
according to the settings of P1-P3 po-
tentiometers. It is possible to adjust the
starting time (in the STAR system) and
time interval of star to delta switching.
Relay operation is triggered by applying
power supply voltage to the L, N supply
terminals. The device is designed to be
mounted in distribution boards (TH35
rail). The LEDs on the front panel in-
dicate power supply (LED green), and
device operating mode (LED red).
