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.
