Notes:
• When using the outputs, the GND 2 connection must also be connected.
• A connection from GND 2 with GND 1 is not necessary. The potential
difference between both wires is maximum 30 V.
• All four outputs have the same electrical properties and can switch ohmic or
inductive loads (relays, valves) up to the permissible maximum current. The
diagram (page 17) shows examples of various consumers. A free−wheeling
diode must be switched in parallel for inductive loads.

When used as a limit switch, the output can be activated as required by over or
undershooting of the limit value. See description of LIV command.
