Contact reliability To ensure the greatest possible switching reliability we recommend a minimum load of:
For silver contacts:
AC/DC = 24 V, 100 mA
For gold-plated contacts (abbreviation "702"):
AC/DC = 10 V, 5 mA
Rating surge voltage 2500 V (via the switching contacts 400 V)
Overvoltage category II

The spacing of the additional contacts can be specified in °C in relation to the setpoint of contact 1.
Prefix - = switching before reaching the setpoint value
Prefix + = switching after reaching the setpoint value
For the synchronized version, specify "0" as the sequence contact gap
