What is a discrete device that can be closed, with no signal, but opens with 28v signal?

I have +28vdc signal (transistor output 50ma). I want to use this signal to turn on a device. the device requires a connection between two pins (remote and -vin) to turn OFF. No connection between the pins turns the device on. How can I change the 28vdc into an open circuit between the pins on the device. I thought about using the NC to C side of a mechanically relay but for various reasons I need to use small discrete electronics like opto-couplers and transistors.

From what I understand you have a +28V signal when active that is able to supply up to 50mA.

A relay would be good as it provides isolated contacts.
The relay would be a 28V type with a coil of 600 ohms or more, and a reverse diode across the coil.

The device input turns off with a short between the pins, and on when it is open, so it seems suitable for an NPN transistor or a relay contact (NC). I assume the device has a positive supply, so its negative side is the device common.

Using an opto isolator...
Connect the +28V output through a 5.6K resistor to the led anode, and the led cathode to the 28V common.. This should provide about 5mA when on. Look up the data sheet to check this is sufficient current.

Connect the + supply of the device through a 4.7K resistor to the collector of the transistor in the opto isolator. Connect the emitter to the device supply common. This provides a 0V signal at the collector when the +28V signal is on. When the +28V signal is off the collector voltage rises. The supply could be +5V or +12V at a guess. You could use a separate 5V to 12V supply for this like a wall adaptor so long as its negative is also connected to the supply common of the device..

A second NPN transistor like a 2N2222 is needed to invert this signal. Connect the collector of the opto-isolator to the base of the 2N2222. Connect the emitter to the supply common of the device and the collector to the remote input of the device.

When the +28V signal is active the transistor will be off, as required, and when the 28V is not present the transistor will be on, closing the pins to turn the device off.

The voltage at the base of the 2N2222 transistor (collector of the opto isolator) will be zero when on and about 0.7V when off.

Best to draw this out so you understand it, and write the voltages on the diagram for documentation.
