1.2.1
AC/DC Inputs
The PM180 is provided with a set of fully isolated AC/DC inputs for a connection to the AC feeders and station
battery:
Three isolated AC voltage inputs (up to 690VAC direct line-to-line input voltage)
Four standard isolated AC current inputs with an extended input range up to 1000% overload (up to 50 Amps
input currents - fault currents)
Optional up to two sets of four isolated current inputs up to 100 Amps, external CT, fault currents detector
AC/DC voltage input (up to 400V AC/DC) for monitoring fourth AC voltage or DC of the station battery
1.2.2
Digital and Analog I/O Options
The PM180 has three I/O expansion slots for removable "hot-swap" plug-in I/O modules:
DI - Digital inputs (16 optically isolated inputs per module, up to 3 modules per device; options for dry contacts,
24-250VDC wet inputs; programmable de-bounce time from 1 ms to 1 sec; free linkage to Sequence-of-Events
Recorder, Fault Recorder, control setpoints, pulse counters and Energy/TOU subsystem)
RO - Relay outputs (8 relays per module, up to 3 modules per device; unlatched, latched and pulse operations,
failsafe operation for alarm notifications; programmable pulse width; direct remote relay control through
communications)
AI/AO - Mixed analog input/output modules (four optically isolated AI and four AO with internal power supplies per
module, up to 3 modules per device; options for 0-1mA, ±1mA, 0-20mA and 4-20mA inputs and outputs; 200%
overload current for 0-1mA and ±1mA AI/AO)
1.2.3
Communications Options
The PM180 has extensive communications capabilities:
Three independent universal serial communications ports (RS-232, RS-422/RS-485, up to 115,200 bps, Modbus
RTU/ASCII and DNP3.0 protocols)
Infrared port (MODBUS RTU/ASCII and DNP3.0 protocols)
Embedded 56K modem for communications through public telephone lines (MODBUS RTU/ASCII and DNP3.0
protocols) – contact SATEC
Ethernet 10/100TX- 100FX port (MODBUS/TCP or DNP3.0/TCP protocols, up to five non-intrusive simultaneous
connections, Telnet service port)
USB 1.1 port (MODBUS RTU protocol, 12 Mbps) for fast local communications and data retrieving
1.2.4
Remote Displays
The PM180 can be ordered with an optional 3 windows LED Remote Display Module (RDM180) or 12 windows
LED Remote Display Module (RDM312) or LCD Remote Graphical Module (RGM180). Both have a fast RS-485
port and communicate with the PM180 through the MODBUS RTU protocol. Remote displays can be located at
distances of up to 0.5 km from the device. The RGM180 can also be ordered with an Ethernet 10/100Base-T port
and can communicate with the PM180 through a local network.
The RDM180 has 3-row (2x4 characters + 1x6 characters) bright red LEDs well suited for dark areas. It allows the
user to view real-time RMS and harmonics measurements, status indication parameters, and perform basic setup
operations when installing and servicing the device.
The RDM312 has 3-row x 4-window (9x4 characters + 3x6 characters) bright red LEDs well suited for dark areas.
It allows the user to view real-time RMS and harmonics measurements, status indication parameters, and perform
basic setup operations when installing and servicing the device.
The RGM180 is equipped with a color graphics LCD display with Touch Panel and has extensive dialog
capabilities, allowing the user to view different fault and power quality information in a graphical form, such as
waveforms, harmonic spectrum, phasors and data trends, review latest fault and power quality reports for fast
fault analysis, and much more.
1.2.5
Upgradeable Firmware
The PM180 uses flash memory for storing device firmware that allows future upgrading of the device without
replacing any hardware component. The new features can be easily added to your device by simply replacing the
firmware through a local RS-232/485 port, USB port or Ethernet port.
