Form A, Solid State Relay (Photo MOSFET)
(60V/0.2A/10)
Data Sheet
Description Features
The ASSR-12XX Series consists of an AlGaAs infrared
Compact Solid-State Bi-directional Signal Switch
light-emitting diode (LED) input stage optically coupled
Single and Dual Channel Normally-off Single-Pole-
to a high-voltage output detector circuit. The detector
Single-Throw (SPST) Relay
consists of a high-speed photovoltaic diode array and
60V Output Withstand Voltage
driver circuitry to switch on/off two discrete high volt -
age MOSFETs. The relay turns on (contact closes) with a 0.2A or 0.4A Current Rating
minimum input current of 3mA through the input LED.
(See Schematic for ASSR-1219 Connection A and B)
The relay turns off (contact opens) with an input volt -
