The 1771-ARC PLC 5 I/O Adapter Module by Allen-Bradley is an I/O adapter module which provides interface between remote I/O distribution panel and the PLC 5 I/O modules and helps collect output image table status data from the distribution panel to easily update the status of outputs terminals of all output modules connected to the PLC 5 I/O Chassis. The 1771-ARC module also reads and transmits input status data from the input terminals of all input modules located on the I/O chassis to the distribution panel. The entire module is located on the I/O chassis adapter slot and uses a serial communication form with a communication rate of 25,000 bits per seconds. The module draws 900mA backplane current at 5V DC and can be placed at a maximum distance of 5,000 cable-feet from the processor. The 1771-ARC module is keyed by connecting the top connector between pin 36 and 38 or connecting the top connector between pins 54 and 56. The 1771-ARC’s operational temperature ranges between 0-60 0C at 5-95% non-condensing relative humidity and it is factory-specified to store under a temperature range of -40-85 0C.
