Overview

Circuit diagrams

The number of digital and analog inputs and outputs can be expanded with terminal expansion board EB1 (Expansion-Board ¹⁾.

On terminal expansion board EB1, there are:

• 3 digital inputs
• 4 bidirectional digital inputs/
• outputs
• 1 analog input with differential signal, for use as current or voltage input
• 2 analog inputs (single ended), that can also be used as digital inputs
• 2 analog outputs
• 1 input for the external
• 24 V supply for the digital outputs.

Terminal expansion board EB1 is installed in a slot in the electronics box.

Boards LBA and ADB must be moved to allow installation.

The terminal strip has the following terminals:

• 3 digital inputs
• 4 bidirectional digital inputs/outputs

The ground cables are protected with a reactor. In the installed state, Terminal 46 is on the top.

Note

The external 24 V supply is necessary and must be designed for the currents of the digital outputs.

Connectable cross-section: 0.14 – 1.5 mm² (AWG 16)
