The Allen-Bradley 1790D-T8BV8B module is a 24 Volts DC CompactBlock LDX base module. A total of 8 universal inputs and 8 universal sourcing outputs are available on the module. The inputs on the 1790D-T8BV8B module are non-isolated sinking or sourcing type inputs. The minimum on-state voltage for the inputs is 9.6 Volts DC, the nominal voltage is 24 Volts DC, and the maximum on-state voltage is 28.8 Volts DC. The maximum on-state current per point is 8 milliamps per point at 28.8 Volts DC. The maximum off-state voltage for the inputs is 5 Volts DC maximum. The nominal input impedance is 4.8 kiloohms. LED status indicators are available on the 1790D-T8BV8B module for each of the inputs. The outputs on the module are of the non-isolating and sourcing type.

The minimum on-state voltage for the outputs on the 1790D-T8BV8B module is 10 Volts DC, the nominal voltage is 24 Volts DC, and the maximum on-state voltage is 28.8 Volts DC. The maximum on-state voltage drop for the outputs is 0.5 Volts DC. The minimum on-state current per channel is 1 milliamp. The maximum off-state leakage for the outputs is 0.5 milliamps. LED status indicators are provided for each of the outputs on the 1790D-T8BV8B module. The module includes an integrated DeviceNet interface. The field power ratings include 24 Volts DC nominal supply voltage, a 10 to 28.8 Volts DC voltage range, and power dissipation rating of 6 milliamps at 28.8 Volts DC per point. The I/O and logic are photocoupler isolated and the isolation voltage is 1250 Volts AC RMS.
