Smart Power Relay E-1048-8I...
Description
The Smart Power Relay E-1048-8I.- is a remotely controllable electronic
load disconnecting relay with three functions in a single unit:
l
electronic relay
l
electronic overcurrent protection
l
status indication
The 7 pin INLINE version is designed for use with various E-T-A
terminal blocks, e. g. 17-P10-Si. A choice of current ratings is available
from 1 A through 20 A. An operating voltage range of DC 9...32 V
allows the connection of DC 12 V and DC 24 V loads.
In order to switch and protect loads remotely, it has until now been
necessary to connect several discreet components together:
- an electro-mechanic relay, control cable and integral contact
to close the load circuit
- an additional protective element (circuit breaker or fuse) for
cable or equipment protection
- a device for current measurement (shunt)
Now type E-1048-8I. combines all these functions in a single unit,
thus minimising the number of connections in the circuit and
thereby reducing the risk of failures.

Applications
Type E-1048-8I. is suited to all applications with DC 12 V or DC 24
V circuits, where magnetic valves, motors or lamp loads have to be
switched, protected or monitored:
- road vehicles (utility vehicles, buses, special vehicles)
- rail vehicles
- marine industry (ships, boats, yachts etc.)
The Power Relay is also suitable for industrial use (process control,
machine-building, engineering) as an electronic coupling relay
between PLC and DC 12 V or DC 24 V load

Integral power electronics provide a wear-resistant switching
function, insensitive to shock and vibration.
Only a fraction of the control power needed by electro-mechanical
relays is required for switching loads. This is important for battery
buffered load circuits which have to remain controlled even with
the generator off line.
The extremely low induced current consumption of less than 1 mA
is absolutely necessary for battery buffered applications.
The load circuit is disconnected in the event of an overload or
short circuit, the trip curve is also suitable for smaller motor loads.
The load circuit is permanently monitored for wire breakage.
The device additionally provides the user with a load current-
proportional analog voltage from 0 to 5 V to allow further
processing of the actual value of the current flow in a power
management system. This voltage signal can also be used for
building up a control circuit or for disconnecting the unit at a low
load current value by means of the external control.
For switching and monitoring loads of 20 A plus it is possible to
connect several units in parallel. Uniform power distribution between
units must be ensured by symmetrical design of the supply cables
(length and cross section).
Coloured label, e. g. red = 10 A, see ordering information.

Parallel connection of channels for loads of 20 A plus, several units of
identical current ratings may be
connected in parallel. To ensure equal
distribution of current between units,
symmetrical design of the supply feed
is necessary (length and cross section).
