Rated protection fuse on UP 10 A fast
Galvanic isolation Yes, per module
Current consumption
From 24 VDC power supply at the terminals UP/L
+ and ZP/M of the CPU/bus module
ca. 2 mA
From UP at normal operation / with outputs 0.15 A + output loads
Inrush current from UP (at power up)

2
s
Max. power dissipation within the module 6 W (outputs OFF)
Weight (without terminal unit) Ca. 300 g
Mounting position Horizontal or vertical with derating
(output load reduced to 50 % at 40
°C per group)
Cooling The natural convection cooling
must not be hindered by cable
ducts or other parts in the switch-
gear cabinet.
NOTICE!
Attention:
All I/O channels (digital and analog) are protected against reverse polarity,
reverse supply, short circuit and continuous overvoltage up to 30 VDC.
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 Inputs
Parameter Value
Number of channels per module 8
Distribution of the channels into groups 4 groups of 2 channels each
Terminals of the channels I0 to I7
Ä Chapter 1.5.1.2.9.3 “Electrical Connection”
