Description
The HSSR-8400 consists of a
high-voltage circuit, optically
coupled with a Light-Emitting
Diode (LED). This device is a
solid-state replacement for single-
pole, normally-open (1 Form A)
electromechanical relays used for
general purpose switching of
signals and low-power ac/dc
loads. The relay turns on (contact
closes) with a minimum input
current, I
F
, of 5 mA through the
input LED. The relay turns off
(contact opens) with an input
voltage, V
F
, of 0.8 V or less. The
detector contains a high speed
photosensitive FET driver circuit
and two high voltage MOSFETs.
This relay’s logic-level input con–
trol and very low typical output
on-resistance of 6
Ω
make it
suitable for switching of audio
frequency signals in telecom
applications. Connection A, as
shown in the schematic, allows
the relay to switch either ac or dc
loads. In this configuration, the
150 mA output current rating
allows it to switch small loads
that are driven from 110 Vac and
220 Vac power lines. Connection
B, with the polarity and pin
configuration as indicated in the
schematic, allows the relay to
switch dc loads only. The
advantage of Connection B is that
the on-resistance is significantly
reduced and the output current
capability increases by a factor of
two.
The electrical and switching
characteristics of the HSSR-8400
are specified from -40°C to
+85°C.
