4.6 STRUCTURAL INFORMATION
The PS1550 power system consists of:
A) a chassis:
1550/RFD
A 19’’rack predisposed to accept 4 stacked units including extractable fan box.
B) an Input Module:
1550/TB-IN is the terminal module for power inputs (230 Vac, 115 Vac, 130 Vdc) also including the terminal
board for alarm relay contacts.
C) an Output Module; three different versions exist (figure 2):
1550/TB-OUT is the standard output module with 16+16 terminals suitable for connections up to 4 Amperes ea-
ch.
1550/TB-OUT 4/20 is an optional output module wih 4+4 terminals suitable for connections up to 16 Amperes
each.
1550/TB-OUT 60 is an optional output module with 1+1 terminals suitable for per a single maximum power con-
nection, (~60 A).
D) two redundancy line Modules which must of the same version; based on the type of system (type-230 or type-
115) there are two possibilities:
1550/LM-230 is the module that permits working with 230 Vac input voltage.
1550/LM-115 is the module that permits working with 115 Vac or 130 Vdc input voltage.
