1. A device designed for controlling and regulating an electro-pneumatic parking brake circuit, the device comprising:
a manual controller configured to actuate a parking brake via the electro-pneumatic parking brake circuit, the manual controller having a first circuit arrangement and a second circuit arrangement, the first circuit arrangement being a digital, bidirectional circuit arrangement and the second circuit arrangement being an analog circuit arrangement; and
control electronics electrically connected to the manual controller,
wherein the first circuit arrangement is connected to the control electronics via a first connection cable and the second circuit arrangement is connected to the control electronics via a second connection cable,
wherein the first connection cable is a digital data transmission channel configured to enable a digital data transmission between the digital circuit arrangement and the control electronics,
wherein the second connection cable is an analog data transmission channel configured to enable an analog data transmission from the analog circuit arrangement to the control electronics,
wherein the digital circuit arrangement and the analog circuit arrangement are redundantly and simultaneously actuatable,
wherein the analog circuit arrangement has a first redundant switching contact connected in series with a first resistor and a second redundant switching contact connected in series with a second resistor,
wherein the second redundant switching contact and the second resistor are arranged in parallel with the first redundant switching contact and the first resistor, and
wherein a capacitor is connected in parallel with the second redundant switching contact and the second resistor.
