| ● |
Monitor three-phase
current and realize the motor’s protection; |
| ● |
Have many digital protected
functions as: short circuit, locked-rotor,
loss of phase/unbalance, ground, definite-time/inverse-time
overload, and etc. Satisfy many start modes
as direct start, and etc; |
| ● |
Standard RS-485 communication
interface and standard ModBus RTU protocol
(8 data bits/1 stop bit /without odd-parity
checking), the communication address (1-247)
and the baud rate (1200, 2400, 4800, 9600,
19200bps) all can be setup. The whole signal
measurement data and meter parameters can
be read out by RS-485 communication interface.
The longest communication distance will
reach to 1.2 km. There are 128 sets of PDM
series meters can be connected on a twisted-pair
wire at most; |
| ● |
Real-time read the measured
values of three-phase amp by communication
interface, and the meter’s protected parameters
can be remote set by the computer; |
| ● |
Event recorder function,
including protection operation value and
operate time, which is available for the
failure analysis of the accident. And it
can read the last 8 event recorders by communication; |
| ● |
3 routes switch quantity
state collection, remote monitor every kind
of the motor’s work states. 2 routes relay
protected control output (remote control),
and 1 route independent alarm control output; |
| ● |
Contact capacity of the control
