Connector
Description
COM A:
Communication port A, or the RJ-45 port. Used for setting tool connection and for IEC 61850, Modbus/TCP,
IEC 104, DNP3 and station bus communications.
COM B:
Communication port B, or the RS-485 port. Used for the SCADA communications for the following protocols:
Modbus/RTU, Modbus I/O, SPA, DNP3, IEC 101 and IEC 103. The pins have the following designations: Pin 1 =
DATA +, Pin 2 = DATA –, Pin 3 = GND, Pins 4 & 5 = Terminator resistor enabled by shorting.
X 1
Digital input 1, nominal threshold voltage 24 V, 110 V or 220 V.
X 2
GND for digital input 1.
X 3
Digital input 2, nominal threshold voltage 24 V, 110 V or 220 V.
X 4
GND for digital input 2.
X 5:6
Output relay 1, with a normally open (NO) contact.
X 7:8
Output relay 2, with a normally open (NO) contact.
X 9:10
Output relay 3, with a normally open (NO) contact.
X 11:12
Output relay 4, with a normally open (NO) contact.
X 13:14:15
Output relay 5, with a changeover contact.
X 16:17:18
System fault's output relay, with a changeover contact. Pins 16 and 17 are closed when the unit has a system
fault or is powered OFF. Pins 16 and 18 are closed when the unit is powered ON and there is no system fault.
X 19:20
Power supply IN. Either 85…265 VAC/DC (model A; order code "H") or 18…75 DC (model B; order code
"L"). PPositiv
