Current and Voltage Monitors
E-T-A Current and Voltage Monitors
E-T-A Current and Voltage Monitors series E-107.. are
designed to monitor electrical circuits for current or voltage
over limits.
G
E-T-A Zero Current Monitors E-1076-SR signal a
current flowing in the monitoring circuit when fixed
current limits are exceeded. They feature a 17 mm wide
rail mounted housing and may also be used to switch on
an elapsed-hour meter. Internal power supply is by
means of the input signal so that no additional wiring is
needed.
G
E-T-A Current Monitors E-1077 offer the possibility to
individually set the MAX and/or MIN limit values by
means of the digital switches provided on the front of
the housing. The response delay may be selected.
Relay contacts provide for potential-free signalization.
Relay status and adjustment error is indicated by LEDs.
G
E-T-A Current Protector E-1078 is designed for low
voltage lighting systems. It monitors the lighting system
rated current that is stored, when it is switched on, in the
primary circuit of the low-voltage transformer. The
rated load is stored either by operation of the push
button on the device or via the light switch. A short-
circuit in the lamp circuit or an overload will cause the
Current Protector to immediately disconnect the system.
The product is available with a rail mounted housing (for
consumer unit installation) or in a housing for surface
mounting at or in the transformer.
G
E-T-A Combi Safety Protection E-1078-911 allows the
simultaneous connection of two powerful loads such
as a washing machine and a dryer to a 16 A socket with
earthing contact. One of the two sockets has priority
and is connected to the washing machine. When the
current required by the washing machine exceeds a set
limit of approx. 15.5 A (during heating), the second
socket is disconnected, and reconnected only when
the current falls to the set lower limit. Appliance
combinations such as dishwasher and hot-water heater
may also be operated this way.
G
E-T-A Voltage Monitor E-1079 monitors set MAX and/or
MIN voltage limits in a circuit. Limit value setting is by
means of the digital switches provided on the front of
the housing. Additional features are relay outputs,
selectable response delay, LED status indication, and
rail mounted housings.
G
E-T-A Voltage Monitor E-1079-600 is available in
a 12 mm wide housing for plug-in mounting utilising
E-T-A socket 17-P10-Si. It is designed to monitor
typical AC and DC supply voltages with set tolerances,
e.g. DC 24 V
±
25 %. The actual voltage is indicated by
two LEDs and a MOS output. This system, too, saves
additional wiring by taking its internal power supply
from the input signal.
All dimensions without tolerances are for reference only. In the interest of improved design,
performance and cost effectiveness the right to make changes in these specifications without
notice is reserved. Product markings may not be exactly as the ordering codes.
