Available In- and Outputs

The 

rain[e]H3 

provides the following outputs:

Pulse Output:

•  1 galvanically isolated open-collector and
•  1 non-isolated open-collector
selectable as

•  Pulse Output

 

◦

Resolution: 

0.01...1 mm

 

◦

Closing time:   10...500 ms (duty cycle of 1:1) 

•  Status Output (heating ON/OFF; rain YES / NO)

Analogue Output:

•  0 / 4…20 mA
•  0...2.5 / 5 V

Serial output:

•  SDI-12

•  RS485 (Talker-, WL ASCII protocol)

•  Ethernet 100 MBit

7.6 

Factory Settings

The factory settings of the 

rain[e]H3

 according to the standard connecting diagram are:

• 

Galvanically isolated output as pulse output

 

Resolution: 

0.1 mm 

 

Closing time:   300 ms

 

Duty cycle:  

1:1

•  Non-isolated output as state output 
 

State “Heating ON / OFF“

•  SDI-12 protocol activated (on SDI-12 Interface, 1200 Bd)
•  Analogue output OFF
•  Heating activated

7.7 Connections

Connection power supply / RS485

Via the A-coded 8-pole M12 plug the power supply and outputs are connected. For the connection several cables 

with different lengths are available. These cables have a unidirectional M12 cable sleeve and only have to be 

plugged on. The pin-assignment is shown in the wiring diagram.

Connection Ethernet interface 

The Ethernet interface is connected by a D-coded M12 plug. For the connection several cables with different lengths 

are available. These cables have a unidirectional M12 cable sleeve and only have to be plugged on. Alternatively 

a D-coded cable sleeve that can be assembled is available. The pins of the Ethernet cable will be assigned by 

insulation displacement technique. Thus, no special tools are needed.

7.8 

TTerminal Assignment

All unused wires must be connected to unused pins or insulated to avoid malfunctions.
