The 1746-IA8 is an AC general purpose input module from Allen-Bradley’s SLC-500 family of processors. The 1746-IA8 has 8 input points and its operating voltage is 85-132 AC with 120V AC being the average at 47-63 Hz. The 1746-IA8 has a heat dissipation rating of 0.27W per point with a minimum of 0.25W and a total of 2.4W.


The 1746-IA8 has 8 points per common. Its backplane current consumption is 0.05A at 5V DC and the current consumption is 0A at 24V DC. In addition, the module’s maximum signal delay is 35ms in the on-state and 45ms in the off-state. The 1746-IA8 has a maximum of 30V AC off-state voltage with a maximum of 2mA off-state current. Its input current is 12mA at 120V AC, its maximum inrush current is 0.8A, and its maximum inrush current time-lapse is 0.5ms.


Although it will change or affect the operating characteristics of the 1746-IA8’s AC input, you can use a current limiting resistor to limit the inrush current. The 1746-IA8 has a communication circuit isolation of 500V DC with the backplane having an isolation voltage of 1500V AC.


The 1746-IA8 is 0.23kg in weight and it measures 13cm x 5cm x 15cm. It is KCC and ROSTECHNADZOR certified, Ul & CUL listed, CE marked, C-tick and KC-certified. It is made for working with programmable controllers. The 1746-IA8 is meant for mounting on an open-type chassis.


At 10-2000Hz, the 1746-IA8’s vibration rating is 1G. It also has a 50G shock when not operating and a 30G shock rating when operating, respectively.
