A 7501-15 card should be used. There are three different models that are powered from different voltages: 7501-15A, 7501-15B and 7501-15C. •7501-15A is powered from a floating 130 Vdc source, usually station batteries. •7501-15B is powered from a grounded -24 Vdc source. •7501-15C is powered from a floating -48 Vdc source, usually station batteries. All cards can accept line voltages up to 150 Vdc and line currents up to 100 mA with a maximum of 5W (current times voltage).
