1 24 V DC
2 0 V DC
3 Point level "OK" or "Not OK" with 24 V DC signal, depends on sensor, point level "OK" is recommended as
a wire break is reliably detected and the relay adopts a safe state
4 NA
Input signal: point level switch with device error
Connectable point level switches:
Every sensor that has two floating contacts (NEx/Ex(d)). One contact is used for point level
detection and the second contact for the device error.

Input signal: continuous level
The sensor must meet the following requirements:
• Output signal: 4 to 20 mA for 0 % to 100 % level
• NEx/Ex(d)
• 2-wire sensors (passive) or 4-wire sensors (active)
