Description
Typical applications
Circuits with inductive load such as
- solenoids
- magnetic brakes etc.
in large plants, e.g. rolling mills where a very high availability is
required.
Features
E-1071-603
The E-T-A Solid State Remote Power Controllers E-1071-603/607 are
electronic control modules suitable for inductive loads such as soleno-
ids, 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 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 (approx. 60 % of the
current rating), thus reducing the operating temperature and extending
the life of the loads.
G
Designed for inductive loads (DC 24 V)
G
Individual adjustment to various load currents (I
= 0.1...3.1 A)
G
Significant reduction of power loss in the load by pulse-controlled
characteristics
G
Short-circuit proof (short-circuit limitation); physical
disconnection from supply after approx. 5 s
G
Inrush current monitoring
G
Physical isolation:
- opto coupler in the control circuit
- physical disconnection from supply
- opto coupler for status outputs
G
Reverse polarity and overvoltage protection in the control, load
and status circuits
G
Control current indication by YELLOW LED
G
O.K. indication by GREEN LED
G
Wire break indication by RED LED (load circuit)
G
Fault indication by RED LED (incorrect setting etc.)
G
Two status outputs for PLCs for function indication (function
signal, ON signal)
G
Temperature disconnection
G
Quick disconnection (do not connect free-wheeling diodes to the
load as the free-wheeling current is controlled electronically!)
