9.9 I/O Expansion module ESIO
With I/O extension modules, WELBA controllers can be extended with additional
digital and analogue inputs or outputs.
- The 6 output relays can be operated either all with 24V DC or all with 230V AC.
- The 5 digital inputs (24V DC) can be configured via jumper as NPN or PNP
inputs. The inputs 1..4 can additionally measure a frequency up to 10 kHz.
- The 2 current inputs 4..20mA with supply voltage connection can be used for
the connection of corresponding sensors
For proper installation, please pay attention to the

9.10 USB module ESUSB
The USB module ESUSB-001 is used to read out stored data from Welba controllers
that can be read out with the Welba KONSOFT configuration software (e.g. WTS-
300 or TW-31/-32).
The USB module is connected directly to the 'RS485 PC' interface of the control unit.
