I/O options (L)
I/O extension and interface modules (+L500, +L501, ...)
Analog and digital I/O extension modules and encoder and resolver interface
modules are inserted in the optional module slots on the drive control unit.
More information: See the user's manuals of the options.
Additional terminal block X2 (+L504)
Description
The standard terminal blocks of the drive I/O board are wired to the additional
terminal block at the factory for customer control wiring.
Cables accepted by the terminals:
• solid wire 0.08 to 4 mm
• stranded wire with ferrule 0.25 to 2.5 mm
• stranded wire without ferrule 0.08 to 2.5 mm
• 28 to 12 AWG.
Stripping length: 10 mm.
Related options: The terminal blocks of all cabinet options (except +M600 to +M606)
are of the same type as terminal block X2.
Note: The optional modules inserted in the slots of the I/O board are not wired to the
additional terminal block. The customer must connect the optional module control
wires directly to the modules.
Thermistor relays (+L505, +2L505)
What the option contains
The standard thermistor relay option includes one (+L505) or two (+2L505) PTC
relays and an auxiliary relay wired to a terminal block. Other numbers of thermistor
relays must be ordered as application engineered.
Description
The thermistor relay is used for the overtemperature supervision of motors equipped
with PTC thermistors. When the motor temperature rises to the thermistor wake-up
level, the thermistor resistance increases sharply. The relay detects the change and
indicates motor overtemperature through its auxiliary contacts.
