Basic I/O

Current Output, active or passive, with HART

Status Output / Control Input

Status Output

Pulse / Status Output

Modular I/O

Current Output, active or passive, with HART

Pulse / Status Output, active or passive, highC or

Namur

Modular carrier with 1 or 2 I/O modules

Each module: 1 out of following 3 in-/output

functions:

Current Output, active or passive

Pulse / Status Output, active or passive, highC or

Namur

Control Input, active or passive, highC or Namur

Profibus DP I/O

Profibus-DP, active

Fieldbus I/O

Profibus-PA or Foundation Fieldbus

RS 485 Modbus

Modbus with or without termination

The options separated by “/” are software selectable (can be changed by the user)

The options separated by “or” are hardware versions (must be ordered as such)

All outputs are passive unless otherwise indicated

HighC means High Current input/output, Namur means that the in-/outputs are according to the NAMUR

NE43 standard
