AB | 1771-IFEK | Analog Input Module

The 1171-IFEK module has up to 16 single-ended inputs or 8 differential inputs which it converts to a proportional 4-digit BCD or 12-bit binary value. It has five voltages and three current input ranges for the users to select. Voltage input ranges are 1 – 5V DC, 0 – 5V DC, -5-5V DC, -10-10V DC, and 0 – 10V DC. Current Input ranges are 4 – 20mA, 0 – 20Ma, and -20 - +20mA. It requires a backplane current load of 500mA at 5V and has a channel update time of 18ms per 8 channels and 36ms per 16 channels. Its wiring is connected to the 1771-WG field wiring arm, eliminating the need for disconnecting the wires when replacing the module. The 1171-IFEK has a maximum power dissipation of 2.5W and maximum thermal dissipation of 8.52 BTU/hr. Keying bands must be put between pins 10-12 and pins 24-26 to accept only this module.
