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 8 normally-open relay outputs
Distribution of the channels into groups 2 (4 channels per group)
Connection of the channels O0 to O3 Terminals 10 to 13
Connection of the channels O4 to O7 Terminals 15 to 18
Reference potential for the channels O0 to O3 Terminal 14 (signal name R0..3)
Reference potential for the channels O4 to O7 Terminal 19 (signal name R4..7)
Relay coil power supply Terminal 20 (positive pole of the process
supply voltage, signal name L+). The nega-
tive pole is provided by the I/O bus.
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
