PM180 Substation Automation Unit 9
AC/DC Inputs
The PM180 is provided with a set of fully isolated AC/DC inputs for connecting to the
AC feeders or 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 2000% overload (10A/20A input currents, to
100 Amps fault currents)

One AC/DC voltage input (up to 400VAC/300VDC) for
monitoring the station battery
Digital and Analog I/O module Options
The PM180 has three I/O expansion slots for hot-swap plug-in I/O modules. The
following I/O options are available:

16 DI x 3 – up to three 16-channel digital input modules: 16
optically isolated inputs per module; options for dry contacts,
10-30V, 20-250V 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.

8 RO x 3 – up to three 8-channel relay output modules: eight
relays per module; unlatched, latched and pulse operations,
failsafe operation for alarm notifications; programmable pulse
width; direct remote relay control through communications.

4 AI/AO x 2 – up to two combined 4-channel AI/AO modules:
four optically isolated analog inputs and four analog outputs
per module with internal power supply; options for 0-1mA,
±1mA, 0-20mA, 4-20mA, 0-50mA and ± 10V inputs and
outputs; 100% overload currents for 0-1mA and ±1mA AI/AO
(0-2 mA and ±2 mA ranges are available).
Communications Options
The PM180 has extensive communications capabilities:
Standard communication ports

Three independent universal serial communications ports
(RS-232/485, RS-422/485 and RS-485, up to 115,200 bps,
MODBUS RTU/ASCII and DNP3.0 protocols)

Infrared port (MODBUS RTU/ASCII and DNP3.0 protocols)

Ethernet 10/100Base-T port (MODBUS/TCP, DNP3.0/TCP
and IEC 61850 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
Optional communication ports
The PM180 has three expansion slots for hot-swap plug-in communication modules.
In addition, each COM module is equipped with a serial RS-422/485 communication
port. The following COM module options are available:

Embedded 56K modem for communications through public
telephone lines (MODBUS RTU/ASCII and DNP3.0 protocols)

Embedded Cellular modem for communication through public
cellular network (MODBUS/TCP and DNP3.0/TCP)

10/100Base TX or 100Base FX (optical port) backup Ethernet
port (MODBUS/TCP, DNP3.0/TCP and IEC 61850 protocols,
