Description Features
The ASSR-5211 is specifi cally designed for high current Compact Solid-State Bi-directional Signal Switch
applications, commonly found in the industrial equip-
Single Channel Normally-off Single-Pole-Single-Throw
ments. The relay is a solid-state replacement for single-
(SPST) Relay
pole, normally-open, (1 Form A) electromechanical relays.
600V Output Withstand Voltage
The ASSR-5211 consists of an AlGaAs infrared light-
0.2A or 0.4A Current Rating
emitting diode (LED) input stage optically coupled to
Low Input Current: CMOS Compatibility
a high-voltage output detector circuit. The detector
consists of a high-speed photovoltaic diode array and
Low On-Resistance:
driver circuitry to switch on/off two discrete high voltage
2.5 Typical for DC-only, 10 Typical for AC/DC
MOSFETs. The relay turns on (contact closes) with a
High Speed Switching:
minimum input current of 3mA through the input LED.
0.7ms (Ton), 0.07ms (Toff ) Typical @ I = 5mA
F
The relay turns off (contact opens) with an input voltage
High Transient Immunity: >1kV/s
of 0.8V or less.
High Input-to-Output Insulation Voltage
The ASSR-5211 connection A, as shown in the schematic,
(Safety and Regulatory Approvals Pending)
allows the relay to switch either ac or dc loads. The con-
nection B, with its advantages of reduced on-resistance - 3750 V for 1 min per UL1577
RMS
and higher output current, allows the relays to switch dc
