1756-IA16 Discrete Input Module

The 1756-IA16 is a Input Module that features Sixteen (16) Discrete input channels. It has Two (2) groups of Eight (8) input channels each group and operates at nominal signal voltage of 120VAC with operating voltage range of 74-132 VAC with frequency of 47-63 Hz. It is compatible for use with any  chassis.

It has Sixteen (16) input channels, grouped into Two (2) groups of Eight (8) points per group. The 1756-IA16 module's operating voltage range is from 74 to 132 Volts AC at a frequency of 47 to 63 Hertz, while both the voltage category and input frequency are 120 Volts AC and 50/60 Hertz, respectively. This module has an input delay time of 10 milliseconds for OFF to ON transition the configured filter time (user-selectable at 1 or 2 milliseconds). For ON to OFF transition, hardware delay is 8 milliseconds maximum plus filter time ( user-selectable at 9 or 18 milliseconds). At 5.1 Volts DC, the current draw is 100 milliamps and there are 2 milliamps of current draw at 24 Volts DC. The total backplane power is 0.58 Watts and it dissipates 5.8 Watts of power at 60 degrees Celsius for and 18.41 BTU/hour of thermal energy. The maximum off-state voltage is 20 Volts and the current is 2.5 milliamps.
