Insulation guaranteed by the power supply insulation from very low voltage parts reinforced; 6 mm air, 8 mm surface; 3750 V insulation
insulation from relay outputs basic; 3 mm air, 4 mm surface; 1250 V insulation
Inputs S1 NTC or PTC, depending on the model
S2 NTC or PTC, depending on the model
DI1 voltage-free contact, contact resistance < 10 ohm, closing current 6 mA
S3 NTC or PTC, depending on the model
DI2 voltage-free contact, contact resistance < 10 ohm, closing current 6 mA
S4 NTC or PTC, depending on the model
Maximum distance between probes and digital inputs less than 10 m. Note: in the installation, keep the power supply and load connections
separate from the probe, digital inputs, repeater display and supervisor cables.

Relay not suitable for fl uorescent loads (neon lights, ...) that use starters (ballasts) with phase-shift capacitors. Fluorescent lamps with electro-
nic control devices or without phase-shift capacitors can be used, within the operating limits specifi ed for each type of relay.

The correct sizing of the power and connection cables between the instrument and the loads is the responsibility of the installer.
Maximum current at terminals 4 and 7 is 12A. In the max load and max operating temp. conditions, the cables used must be suitable for ope-
ration up to 105°C.
