The Allen Bradley 1771-ILK is an isolated analog input module. The 1771-ILK has 8 differential inputs which are 1000 Volt individually isolated. This module is conformally coated which makes is suitable to be operated in extreme and harsh industrial environments. The module has a per channel update time of 500 milliseconds, voltage ranges of -10 to +10 Volts DC, 0 to 10 Volts DC, -5 to +5 Volts DC, +1 to +5 Volts DC, and 0 to +5 Volts DC. The 1771-ILK isolated analog input module has a 15-bit resolution and current ranges of -20 to +20 milliAmps, 0 to +20 milliAmps, and +4 to +20 milliAmps.

The 1771-ILK uses natural binary data format or BDC scaling of +-9999 and puts a current load of 1.3 Amperes on the backplane. The 1771-ILK is meant to be mounted in a chassis where it should be properly grounded. The isolated analog input module has a direct current signal off delay (typical) of 20-milliseconds (+/- 9 milliseconds) and 24-milliseconds (+/- 9 milliseconds) alternating current signal off delay. The 1771-ILK uses the 1771-WD wiring arm to minimize wiring needs in case of module replacement. The 1771-ILK module has LED indicators on its front side to help in troubleshooting and or monitoring the module and all the devices connected to it. When mounting the 1771-ILK ventilation guidelines should followed to minimize overheating and maximize the operation. The 1771-ILK is marine certified and should be operated within a relative humidity not exceeding 95% without condensation. All guidelines should be followed when mounting and operating the 1771-ILK isolated analog input module.
