Power supply The control voltage Us needs to be applied to the A1/A2 terminals of the
side mounted electronic module, this supplies power for the magnetic coil
and the remaining lifetime indication.
Control inputs The control inputs for the contactor are connected on the 7-pole terminal
block (The terminals supplied with the unit have Cage Clamp-Technology).
Switching from Auto-
matic-/Manual control
Control of the contactor can be switched from automatic control to manual
control using the input terminals H1/H2. Manual control may be required at
start-up or to switch the contactor after loss of power on a PLC or
SIMOCODE-DP device.
Control with a PLC with
24 V DC
Control using relay out-
puts
Control directly from a PLC with
24 V DC without a coupling
device
• via PLC -control input IN+/IN–
(EN 61 131-2/Type 2)
• Current consumption ≤ 30 mA
• Operational range17 to 30 V DC
Note
H2 and A1 are internally con-
nected and therefore have the
same voltage potential

On-site control option
Control using relay outputs, for
example from:
•PLC
• SIMOCODE-DP (3UF5)
Relay outputs can control the
contactor through the H1/H2 ter-
minals.
The relay contacts are loaded to
about 5 mA plus the control volt-
age applied at the A1/A2 termi-
nals
