The 1769-IA81 module is a compact digital input module. It is manufactured by Allen-Bradley/Rockwell Automation in the CompactLogix series. The 1769-IA81 digital input module operates on AC voltage. It is an open type of module that does not have an enclosure, which makes it easy to install but leaves it unprotected from common industrial pollutants like dust, small pieces of debris, and liquids. The 1769-IA81 digital input module can be installed inside an enclosure for protection and it can be mounted on either a panel or a DIN Rail.

The Allen-Bradley 1769-IA8I is a programmable logic controller module that runs on 120V AC. It is a digital CompactLogix module that is ideal for small and mid-size applications that require safety parameters, motion control, and complex communication. The module provides an integrated serial port and offers a memory ranging from 2-3 MB. The 1769-IA8I has display LEDs and an open-style enclosure that measures 87 mm in depth, 118 mm in height, and 35 mm in width. It weighs approximately 270 g. The module's mounting location is a DIN Rail Mount or a Panel Mount. It features 8 individually-isolated digital AC inputs. The 1769-IA8I module has a 100-120V AC voltage category. Its operating voltage ranges from 79-132V AC at 47-63 Hz. Its input delay for OFF and ON is 20 ms and its current draw at 5.1 V is 90 mA. The module's OFF-state voltage is 20V AC max and the OFF-state current is 2.5 mA max. Its minimal ON-state voltage is 79V AC and the heat dissipation is 1.81 W at most. The module's minimal ON-state current reaches 5 mA at 74V AC and reaches 12 mA at 120V AC at most. Its peak inrush current is 250 mA. The 1769-IA8I's max input impedance is 12 kΩ at 50 Hz and 10 kΩ at 60 Hz. It comes with a 132V AC working isolation voltage, tested to withstand 1517V AC for 1s or 2145V DC for 1s in dielectric tests. The 1769-IA8I has IEC Class 2 reinforced insulation and has been tested by input point-to-bus and group-to-group. The Allen-Bradley 1769-IA8I has an operating temperature of 0-60°C and a -40 - 85 °C storage temperature. It has a relative humidity of 5-95% non-condensing. Its operating vibration is 5g at 10-500 Hz with an operating relay of 2g. Its operating shock in a panel mounting is 30g and the operating shock of 20g on a DIN rail mount. The non-operating shock on a panel mount is 40g and it is 30g on a DIN rail mount.
