Version Changes
The P634 is now fitted with an improved power supply
module.
Note that the voltage range has changed for DC input:
●
For the DC / AC variant, the range is
o
now 60 … 250 VDC / 100 ... 230 VAC
o
(previously 48 … 250 VDC / 100 ... 230 VAC).
●
For the DC-only variant, the range is
o
now 24 … 60 VDC
o
(previously 24 VDC).
A new communication module (“REB” = “Redundant
Ethernet Board”) is now available as an ordering
option.
This module can be used for redundant communication
via IEC 61850 and may be fitted to slot 2, as an
alternative to the other communication modules. The
following communication protocols are supported:
●
SHP (Self-Healing Protocol).
●
RSTP (Rapid Spanning Tree Protocol).
●
DHP (Dual-Homing Protocol).
A detailed description of the module and the
appropriate network connections is available as a
separate document (“Redundant Ethernet Board,
Application Guide”).
