The Allen-Bradley 1756-IV32 digital input module features 32 inputs grouped in sets of 16, optimized for use with ControlLogix 1756 chassis systems, requiring an RTB such as the 1756-TBCH or 1756-TBS6H for connectivity. Designed for 12/24 Volts DC operations, this module supports an operating voltage range from 10 to 30 Volts DC, drawing 120 milliamps at 5.1 Volts and 2 milliamps at 24 Volts, with a nominal input voltage of 24 Volts DC. With a maximum power dissipation of 4.1 Watts at 60 °C and a thermal dissipation of 14 BTU/hour, the module reliably processes signals with a backplane power consumption of 0.66 Watts, ensuring efficient performance with a maximum inrush current of 250 milliamps and a sophisticated input delay system adaptable to various user-configurable filter settings.
