The 1746sc-IA8I is one of the best and most economical isolated circuit input modules that is manufactured by Allen-Bradley. The installation and operational processes of the 1746sc-IA8I are identical to those of other Allen-Bradley isolated circuit input modules, which makes for easy installation and operation. For the purposes of improving overall system integrity and eliminating crossing phases, the 1746sc-IA8I has a 1500 Volt input-to-input isolation setup. This allows for the use of multiple input types with the 1746sc-IA8I. This allows the 1746sc-IA8I to synchronize with various types of input devices and proximity switches easily as well as simplifying troubleshooting and maintenance, monitoring of high voltage control circuits, and eliminating the use of unnecessary relays and transformers.

The high-efficiency level of the 1746sc-IA8I comes from the 8 separate-common isolated inputs that are featured in the 1746sc-IA8I. The device has an excellent operating voltage range of 80 to 150 Volts AC at 47 to 63 Hertz and 85 to 170 Volts DC, respectively. The 1746sc-IA8I is universally compatible with a wide range of switches that include proximity switches, selector switches, and limit switches. Up to 8 input devices can be used simultaneously with the 1746sc-IA8I. The 1746sc-IA8I’s nominal current inputs are at 16 MA at 120 Volts AC and 2.5 MA at 120 Volts DC. The maximum input inrush current of the 1746sc-IA8I is 0.7 Amps at 120 Volts AC. The power dissipation rate of the device is 4 Watts at 120 Volts AC and DC. The 1746sc-IA8I is perfect for input, sourcing, and sinking in a discreet manner.
