Allen-Bradley 1769-IA16 16-Point 120V Input Module

The Allen-Bradley 1769-IA16 is a CompactLogix 16-point, 120 VAC input module designed for the 1769 Compact I/O backplane. Each of its 16 inputs accepts 100/120 VAC at 47–63 Hz, with an operating range of 79–132 VAC and an input delay of 20 ms (on) and 20 ms (off). The group uses internally connected commons, with an isolation rating between input points and the bus of 1517 VAC for 1 s or 2145 V DC for 1 s. Electrical characteristics include an input impedance of 12 kΩ at 50 Hz (and 10 kΩ at 60 Hz), off-state voltage up to 20 VAC and off-state current up to 2.5 mA, and on-state current from a minimum of 5 mA at 74 V AC to a maximum of 12 mA at 120 V AC, with up to 250 mA inrush. The module draws about 115 mA from the internal supply and dissipates up to 3.30 W, and weighs approximately 280 g with dimensions around 118 × 35 × 87 mm (4.65 × 1.38 × 3.43 in). Intended for industrial automation, it provides 16 digital inputs that monitor 120 VAC field devices such as sensors or switches and interfaces via the Compact I/O backplane for real-time status signals in a Rockwell Automation system.
