Solid State Remote Power Controller E-1071-623/627
Description
The E-T-A Solid State Remote Power Controllers E-1071-623/627
are electronic control modules suitable for inductive loads such as
electromagnetic valves (solenoids), magnetic brakes etc.
They are used:
•
•
•
for safe and quick switching of loads
for monitoring the electrical condition of the loads
for compensating different cable lengths
The load connected to the relay should be operated with a higher voltage
(DC 28…60 V) than its rated voltage (DC 24 V) because the load current
is controlled electronically (pulse-controlled characteristics). This is
to ensure that in industrial plants with different cable lengths (supply
cables, load cables) an increased inrush current can be applied to
each load. During hold duty the load current is reduced to a smaller
value (approx. 60 % of the current rating), thus reducing the operating
temperature and extending the life of the loads.
E-1071-623
The double pole electronic switching output prevents inadvertent
start-up or dangerous machine movements as may arise upon a
ground fault in systems with ungrounded power supply (‘IT systems’)
(see EC Machinery Directive or EN 60204 part 1 “Safety of Machinery
- Electrical Equipment of Machines”, para 9.4.3.1).

General data
The current rating of the applicable load at its rated voltage should
be set between 0.1...3.1 A. The holding current of the load is internally
adjusted to 60 % of the set current rating. This holding current can
be measured by means of a voltmeter connected to the 2 mm current

The current rating is set by means of a rotary switch (switch
setting 0 A - 1 A - 2 A) and a 270° potentiometer (setting range
between 0.1...1.1 A). The sum of the two settings should equal the
current rating of the load.

Faulty setting of current rating
The red LED (failure indication) blinks in the event of a faulty setting.
The load is disconnected only after approx. 15 sec if the current rating
value is not corrected and the red LED will be permanently lighted.
Reset is only possible by switching on again.
The tolerance range, in which faulty setting will not be indicated, is
approx. 30 % of the holding current.

The load capacity is no longer ensured when the minimum operating
voltage falls below UB min = 28 V. The RED LED (fault) will indicate
and the output will be switched off. Only when an operating voltage
of 29.4 V is exceeded will the load be switched on again and normal
operation status is restored.
