Terminal expansion board EB2The number of digital and analog inputs and outputs can be expanded with terminal expansion board EB2 (Expansion-Board 2). On terminal expansion board EB2, there are: - 2 digital inputs
- 1 relay output with changeover contacts
- 3 relay outputs with NO contacts
- 1 analog input with differential signal, for use as current or voltage input
- 1 analog output
- 24 V supply for the digital outputs.
Terminal expansion board EB2 is installed in a slot in the electronics box. Boards LBA and ADB must be moved to allow installation. Terminal 490 Load rating on the relay contacts |
