The DL2503 will scale one or two separate analogue inputs, so that the sensor signal matches the physical value – be that temperature, pressure, flow rate or whatever is being monitored.

The user can assign switched output signals from the analogue, to set trips or control another operation. These outputs are both relay and solid-state transistor.

When two input signals are received the DL2503 also offers a comparison mode, adding or subtracting the two signals and supplying the result as a single analogue signal, or pulse-width modulated signal, scaled as required.
