Solid State Remote Power Controller E 1048-600
At the appropriate input level (>8.5 V), the opto decoupled input in the
SSRPC will switch on a power transistor to connect the load to the plus
pole of the load circuit supply (U
B
).
The transistor will switch off when
- the control voltage (U
E
) is removed
- there is a short-circuit/overload in the load circuit.
Status indication is provided by two LEDs (red and green).
Thermal-magnetic overload protection occurs at approx. 1.4 times rated
current. See time/current characteristic curves.
The SSRPC is fitted with blade terminals DIN 46244-A6.3-0.8 and is
suitable for plug-in mounting with various E-T-A sockets.
Control circuit
ON condition:
If a voltage higher than 8.5 V is applied to the input terminals (-IN, +IN),
the control current (from the PLC) will flow through the opto coupler.The
output transistor will be conductive.
OFF condition:
A control voltage lower than 5 V will switch the output transistor off.
Load circuit
The load circuit switches depending on the control signal (“0” or “1”). It
is electronically monitored for faults. In the event of a short-circuit the
circuit is disconnected after max. 250
μ
s whilst upon inadmissible
overload it is disconnected according to the time/current curves shown.
Fault indication output
The fault indication circuit (F+, F-) is opto decoupled from the load and
control circuit.
In the OFF condition (i.e. 0 < U
E
< 5 V), this circuit will provide wire break
indication, with the transistor output being open.
In the ON condition, the circuit will provide short-circuit and overload
monitoring and indication.
