Example of connection designation for an output:

x20

(1) Q 1.6

1)

Output 6 (6th bit); 0 to 7 possible

Address of output byte (1st byte);

0 to 255 possible

Q = Output

1st terminal L+ (not specified in the ad- dress)

Data Memory and S5 Bus Control

g	=	Green LED (status indicator)
r	= Red LED (short-circuit indicator)
F+/F-	=	Enable input

1)Changeover of enable mode with jumper X20: Jumper inserted = Enable input active (factory setting) Jumper open = Enable input inactive.

2)The terminal is not connected internally. When this terminal is connected to the output voltages, the clearances in air and leakage paths are no longer adequate to UL and CSA, but comply with VDE.

3)By connecting L- to pin 42, a leading and trailing connection to 0 V ground is created on the module when it is inserted and removed.
