The 1769-IA8I is a 1769 Compact I/O module. This module is an AC input module that is designed with individually isolated input channels. It is capable of receiving 79-132VAC voltage signal range with frequency of 47-63 Hz.

The 1769-IA8I input channels has input response time of 20 ms for OFF to ON and OFF to ON signal transitions. It draws 5.1 mA current from the backplane and dissipated heat amounting to 1.81 Watts. The module’s minimum ON-state signal voltage is 79 VAC while the maximum ON-state signal voltage is 132VAC. Similarly, the minimum ON-state current is 5 mA at 74VAC and maximum ON-state current of 12mA at 120VAC. Conversely, the maximum OFF-state signal voltage is 20VAC while the maximum OFF-state current is 2.5 mA.

The 1769-IA8I individually isolated input channels provides isolation rating of 1517V AC for 1 s or 2145V DC for 1 s. Isolation is measured from the input point to bus and group to group 132V AC working voltage isolation according to IEC Class II reinforced insulation. This module is a single slot width module that mount directly to any available slot of the chassis. It supports DIN rail and direct panel mounting, following the standard supported mounting methods of the Logix platform.

The 1769-IF8I must not be mounted more than Eight (8) modules away from the power supply. This is referred to as the power supply distance rating. Additionally I/O power supply such as 1769-PA2, 1769-PB2, 1769-PA4, 1769-PB4 may be installed to provide sufficient power supply to the CompactLogix bus.

It also comes with LED status indicators and can be mounted using a DIN rail or panel mount. The 1769-IA8I module can either be Series A or B and it can be configured using the RSLogix5000 software. The entire module measures 1.38 x 3.43 x 4.65 inches and has an open-type enclosure.

The input voltage of the 1769-IA8I ranges from 79 to 132 Volts AC at 47 to 63 Hertz, while its voltage rating is 100 to 120 Volts AC. It has a maximum off-state voltage of 20 Volts AC and a minimum on-state voltage of 79 Volts AC. It also has an off-state current of 2.5 mA and an on-state current that ranges from a minimum of 5 mA at 74 Volts AC and a maximum of 12 mA at 120 Volts AC. The 1769-IA8I’s current draw is 90 mA at 5.1 Volts and an inrush current of 250 mA. The power dissipation is at 1.81 W while the input impedance is 12 KΩ at 50 Hertz and 10 KΩ at 60 Hertz. It also has a power consumption of 33.6 W. The 1769-IA8I has a non-condensing relative humidity of 5 to 95% and a delay response time of 20 milliseconds for both the ON and OFF states. It has an operating vibration of 5g at 10 to 500 Hertz and a relay operating vibration of 2g. The 1769-IA8I’s operating shock is 30g when panel-mounted and 20g when DIN-rail-mounted, its relay operating shock is 7.5g when panel-mounted and 5g when DIN rail-mounted and its non-operating shock is 40g when panel-mounted and 30g when DIN rail-mounted. The 1769-IA8I’s operating temperature range is from 0 to 60 degrees Celsius while its storage temperature is from -40 to 85 degrees Celsius.
