ABB AC500 PLC - Technical Data of the Digital Outputs

Only additional details are therefore documented below.
Parameter Value
Process supply voltage L+
Connections Terminals 19 for L+ (+24 VDC) and 20
for M (0 VDC)
Rated value 24 VDC
Current consumption via L+ 50 mA
Max. ripple 5 %
Protection against reversed voltage Yes
Rated protection fuse for L+ Recommended; the outputs must be
protected by an 5 A fast fuse
Current consumption from 24 VDC power supply at
the L+/UP and M/ZP terminals of the CPU/bus
module
Ca. 5 mA
Galvanic isolation Yes, between the output groups and the
rest of the module
Isolated groups 2 (8 channels per group)
Surge-voltage (max.) 35 VDC for 0.5 s
Max. power dissipation within the module 2.0 W
Weight Ca. 160 g
Mounting position Horizontal or vertical
Cooling The natural convection cooling must not
be hindered by cable ducts or other
parts in the switch-gear cabinet.
No effects of multiple overloads on isolated multi-channel modules occur, as every channel is
protected individually by an external fuse.
Technical Data of the Digital Outputs
Parameter Value
Number of channels per module 16 normally-open relay outputs
Distribution of the channels into groups 2 (8 channels per group)
Connection of the channels NO0 to NO7 Terminals 1 to 8
Connection of the channels NO8 to NO15 Terminals 10 to 17
Reference potential for the channels NO0 to
NO7
Terminal 9 (signal name R0..7)
Reference potential for the channels NO8 to
NO15
Terminal 18 (signal name R8..15)
Relay coil power supply Terminals 19 and 20 (signal names L+ and
M)
Indication of the output signals 1 yellow LED per channel; the LED is on
when the output signal is high (signal 1) and
the module is powered via the I/O bus
Way of operation Non-latching type
No effects of
multiple over-
loads
