EL3060 CONTINUOUS GAS ANALYZERS | OI/EL3060-EN REV. A 39
Electrical connections
Terminal assignment in the terminal housing of the control unit
NOTE
Not all signal input and outputs are actually assigned, depending on the
configuration of the gas analyzer.
Digital inputs
Opto-electronic coupler with 24 V DC internal power supply. Activation with
floating contacts or with Open-Collector drivers NPN.
Digital outputs
Floating double-throw contacts, max. contact load rating 30 V/1 A. The relays
must always be operated within the specified data. Inductive or capacitive
loads are to be connected with appropriate protective measures (freewheel-
ing diodes for inductive and series resistors with capacitive loads).
