- Input frequency range: 47-63 Hz
- Input current: 50 mA @ 5 V
- Input impedance: 10 kΩ
- Output voltage range: 5 VDC
- Output current: 10 mA
- Operating temperature range: 0-60 °C (32-140 °F)
- Storage temperature range: -40-85 °C (-40-185 °F)
- Dimensions: 3.8 x 8.9 x 1.2 cm (1.5 x 3.5 x 0.5 in)
- Weight: 0.2 kg (0.45 lbs)
Usage methods
The 1746-IA8 is installed in the SLC 500 PLC chassis. The input channels are connected to sensors or switches, and the output channels are connected to other PLC modules or devices. The 1746-IA8 is programmed using the RSLogix 500 software.
Product advantages
- The 1746-IA8 is a reliable and durable product that has been proven in many industrial applications.
- It is easy to install and use.
