5.2.7 I/O terminals

Functions Terminals with different functions are available for extra-low voltage level. These in-

clude the following terminals, for example: The text in brackets indicates the function ac-

cording to the order designation.

– Digital input and output terminals (DI, DO)

– Analog input and output terminals (AI, AO)

– Relay terminals (DOR)

– Temperature measurement terminals (TEMP)

– Communication terminals

– Communication terminals with serial interface (RS232, RS485/422)

– Inline/AS-i master (ASI MA)

– DALI terminals (DALI)

– Master terminals (IFS MA, PB MA)

– Position detection terminals (INC-IN, IMPULSE-IN, SSI-IN)

– Terminals for open and closed-loop control

– Function terminals (PWM, CNT)

– Positioning terminals (SSI, INC)

– Temperature controller terminals (TEMPCON)

Digital input and output terminals and relay terminals are available for the low voltage

area.

The terminals are available in different sizes. This enables you to set up the station in a

modular way so that it meets your application requirements.

Protection Overload protection of the system is provided centrally by a fuse in the power terminal or

by an external fuse provided by the operator. The rating of the preconnected fuse must

be such that the maximum load current is not exceeded. For the maximum permissible

load current of an I/O terminal, please refer to the terminal-specific data sheet.

Carrying capacity of the

jumper contacts

The maximum current carrying capacity of the jumper contacts on the side is specified in

Section “Current and voltage distribution” on page 91.

Grounding (FE or PE) Connection to functional ground (24 V DC area) or protective ground (120 V AC or

230 V AC area) is established via the corresponding potential jumpers when the terminal

is snapped onto the previous terminal.
