Description:

The DIH-134 is a State-of-the-Art Photovoltaic Solid State Relay designed for 28V DC Aircraft power applications where

speed, current overload protection and immunity to transient voltages are critical.

The DIH-134 contains current limiting networks and thermally sensitive integrated circuits that disable the output, if the

output MOSFETs approach an unsafe operating temperature. Because the thermally sensitive integrated circuits have

built-in hysteresis, the output MOSFETs are automatically restarted when a safe temperature is reached. This auto restart

feature eliminates the need for system restart signals. If the overload condition continues to exist, the cycle is repeated; if

the overload condition is removed, the relay returns to normal operation.

The package contains two independent N/O relays, with separate LED inputs and optically isolated power MOSFET

outputs. Each relay, A or B, is capable of carrying 350mA DC continuous current and 500mA 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-134 is also

available screened to military specifications, as required.
