Switching between 10BASE-T and
100BASE-TX takes place automatically.
Switching between half and full duplex
takes place automatically.
When terminating, short-circuit
terminals 17 and 18 with the
shorting bar.
*1 If Ethernet communication is used, the
RS-485 communication interface is used
specifically for the Ethernet-serial gate-
way function.
*2 In the case of the PR300 with the
demand measuring function, the demand
alarm release is selected.
Voltage signal
ON signal: 4.5 to 25 V DC
OFF signal: within
Ϯ1V DC
