Each package contains two independent relays. One is normally closed (N/C) and the other is normally opened (N/O). Both relays are built with separate input LEDs and optically isolated power MOSFET outputs. The N/C and N/O outputs are able to operate either AC or DC. Connecting the two inputs either in series or parallel (depending on available power supply) will convert the (N/C), (N/O) of DIH-1378 from 2 single SPST relays into a single SPDT configuration. Each relay, A or B, is capable of carrying 150mA AC or DC continuous current and 250mA DC peak current. Each LED optically couples to a Photovoltaic (PV) IC chip which responds by generating a voltage. This voltage is internally connected to the Gate and Source terminals of the output MOSFETs, thus controlling their current. The DIH-1378 is also available screened to military specifications, as required.
