The 1756-IH16I is a DC input module from Allen-Bradley. the module has 16 individually isolated inputs and operates at 125 Volts DC sink or source while its rated operating voltage is between 90 and 146 Volts DC. The 1756-IH16I has an OFF to ON input delay time of 2 milliseconds (hardware delay with the filter time included) and it provides a filter duration which is selectable by the users. The user-selectable filter durations range between 0 and 2 milliseconds. For the ON to OFF input delay times, the 1756-IH16I accommodates a maximum delay from the hardware of 6 milliseconds combined with the filter time. The user-selectable ON to OFF delay times for the 1756-IH16I range between 0 and 18 milliseconds.

The 1756-IH16I DC digital input module has a normal input voltage rated at 125 Volts DC. The module draws a current of 125 mA and 3 mA at 5.1 Volts DC and 24 Volts DC, respectively. At 140 degrees Fahrenheit, the 1756-IH16I dissipates 5 watts. The minimum and maximum on-state current for the module is rated at 1 and 3 mA at 90 and 146 Volts DC. The 1756-IH16I has an off-state current of 0.8 mA and a maximum off-state voltage of 20 Volts DC. The 1756-IH16I input module uses the 1756-TBCH and the 1756-TBS6H removable terminal block housing and it has an open style enclosure rating. When not in operation, the 1756-IH16I should be stored at a temperature of between -40 and 85 degrees Celsius and it can withstand a shock of 50 G. the 1756-IH16I has 6 kilovolts contact discharges and ESD immunity. Additionally, the 1756-IH16I can accommodate an oscillatory surge of 3 kV.
