About 1746-IB16

The 1746-IB16 SLC 500 General Purpose DC Input Module by Allen-Bradley is a digital AC input module with 16 sinking 24V DC inputs and 16 points per common. The module is located on the I/O chassis slots of the SLC 500 Chassis and uses a removable terminal block (RTB). It has a sinking operational voltage range between 10 and 30V DC and draws a maximum backplane current of 0.05A at 5V DC. The 1746-IB16 has a maximum signal delay time of 8ms for both ON and OFF on the input points, the module has a maximum drop voltage of 5V DC in the OFF state. It has a maximum leakage current of 1mA and has a nominal input current of 8mA at 24V DC across the entire module. The 1746-IB16 has a net heat dissipation of 0.22W on each input point and a total heat dissipation on the entire module is 3.6W. It operating temperature ranges between 0 and 60 °C (32 and 140 °F) in a surrounding with 5-95% relative humidity, and when not in use, should be stored at a temperature range between -40 and 85 °C (-40 and 185 °F). The 1746-IB16 has a tested operational shock rating of 30G and is designed to withstand an operational vibration of 2.5G at 57-200 Hz operational frequency. It has a NEMA standard ICS 2-230 rated noise immunity and is UL-A196, CSA, and C-UL Class I, Division 2 Hazardous Environment-rated. It offers Electro-optical isolation tested at 1500V, between input terminals and control logic, and is UL, CSA, and CE-certified.
