Ordering information
Solid State Remote Power Controller E-1071-803
The E-T-A Solid State Remote Power Controllers E-1071-803 are
electronic control modules suitable for inductive loads (DC 24 V) such
as solenoids, magnetic brakes etc.
They are used
G
for safe and quick switching of loads
G
for monitoring the electrical condition of the loads
G
for compensating for different cable lengths
The load connected to the relay should be operated with a voltage higher
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 (between 25 % and
75 % of the current rating), thus reducing the operating temperature
and extending the life of the loads.
