The Allen Bradley 1746-IA8I is an input module with 8 isolated circuit inputs. The 1746-IA8I fits only into Allen-Bradley 1746 I/O racks for the SLC-500 modular and fixed systems. The 1746-IA8I has broad operating ranges, increasing its diversity of uses. It can be used with limit switches, selector switches, float switches, push-buttons and photo sensors. Additionally, the 1746-IA8I can monitor starter outputs or relay directly.


The 1746-IA8I has 1, personally isolated, point per common. Its operating voltage category is 100-120V AC at 50-60Hz and the source/sink voltage category is 100-120V DC. Its operating voltage is 80-150V AC at 47-63Hz. The 1746-IA8I has a nominal input current of 16mA at 120V AC and at 60Hz and that current is 2.5mA at 120V DC. The 1746-IA8I has a maximum input inrush current of 0.7A at 120V AC. It also has a maximum input signal delay of 17ms at 120V AC or 7ms at 120V DC during an OFF-to-ON operation, and the delay is 45ms at 120V AC or 40ms at 120V DC during an ON-to-OFF operation.


The 1746-IA8I input module has a maximum Off-state current of 4mA at 20V AC and 0.5mA at 20V DC. The 1746-IA8I’s maximum thermal dissipation is 0.5W at 120V AC/DC or 0.75W at 150V AC/DC per point and maximum total wattage of 4W at 120V AC/DC or 6W at 150V AC/DC.


The 1746-IA8I draws a 0.11A maximum backplane current at 5V and a 0A backplane current at 24V. The 1746-IA8I module has a 1500V point-point isolation. These means overloads, shorts, and other interferences in 1 circuit won’t affect devices on other circuits and different power sources can be connected to the same module without damaging components.


The 1746-IA8I’s operating temperature is 0-60° C and it has a storage temperature rating of -40-85° C at a relative humidity level of 5-95% in a noncondensing environment. The 1746-IA8I is UL/C-UL (class I, div 2, groups ABCD) for EMC and 73/23/EEC for low voltage-certified.
