I/O module (optional expansion module)
The I/O module is connected and wired in the factory.
It is used to expand the inputs and outputs Control Touch controller.
Six digital inputs and six digital outputs are used to process messages and
alarms:
Inputs
Three inputs, N.C. with 24 V self potential for standard settings.
•
External temperature monitoring
•
Minimum pressure signal
•
Manual make-up of water
Three inputs, N.O. with 230 V self potential for standard settings.
•
Emergency-Off
•
Manual operation (e.g. for pump or compressor)
•
Manual operation for the overflow
Outputs
Potential-free as changeover contacts. Default settings for messages:
•
Make-up fault
•
Below minimum pressure
•
Above maximum pressure
•
Manual or Stop operation
Note!
•
For the default settings of the I/O modules, see Chapter 5.2.3 "I/O
module default settings" page 7
•
All digital inputs and outputs can be set freely as option. Settings
to be made by Reflex Customer Service, see chapter 13.1 "Reflex
Customer Service" on page 23

Danger to life from electric shock!
Risk of serious injury or death due to electric shock. Some parts of the main
board may still carry 230 V voltage even with the device physically isolated
from the 230 V power supply.
•
Before you remove the covers, completely isolate the device controller
from the power supply.
•
Verify that the main circuit board is voltage-free.

Terminator settings in RS-485 networks
Examples for the activation and deactivation of terminators in RS–485 networks.
•
DIP switches 1 and 2 are located on the main board of the controller.
•
Maximum length for an RS–485 connection is 1000 metres
