The 1734-IE8C is a POINT I/O 8-Channel High Density Current Input Module that is manufactured by Allen-Bradley and Rockwell Automation. The 1734-IE8C has 8 single-ended, non-isolated, current inputs and a resolution of 16 Bits over 0…21 milliamperes. Input current terminal is 4…20 milliamperes and 0…20 milliamperes. The 1734-IE8C has a current terminal absolute accuracy of 0.1% Full Scale at 25 degrees Celsius. Current terminal accuracy drift with temperature is 30 ppm per degree Celsius. Input impedance is 60 Ω and it has a Delta Sigma conversion type. Common mode rejection ratio for the 1734-IE8C is -120 decibels. Additional input specifications include Signed Integer data format, maximum overload that is fault protected to 28.8 Volts DC, factory calibration, and logic side indicators for network, module, and input status.

General specifications include a maximum POINTBus current of 75 milliamperes, maximum power dissipation of 0.6 Watts at 28.8 Volts DC, and maximum thermal dissipation of 2.0 British Thermal Units (BTU) per hour at 28.8 Volts DC. The 1734-IE8C has an isolation voltage of 50 Volts, tested at 1500 Volts AC for 60 seconds (inputs and field power to system – no isolation between individual inputs or inputs to field power). The 1734-IE8C has a backplane supply voltage of 5 Volts DC and available input currents of 4…20 milliamperes and 0…20 milliamperes. It has approximate dimensions of 56.0 x 12.0 x 75.5 millimeters, or 2.21 x 0.47 x 2.97 inches. The 1734-IE8C has an approximate weight of 36 grams, or 1.235 ounces. It has an open-style enclosure type rating. Environmental specifications for the 1734-IE8C include an operating temperature that ranges between -20 and 55 degrees Celsius (-4 to 131 degrees Fahrenheit) and a maximum surrounding air temperature of 55 degrees Celsius (131 degrees Fahrenheit). Non-operating temperature ranges between -40 and 85 degrees Celsius (-40 to 185 degrees Fahrenheit) and relative humidity is 5% to 95% (non-condensing).
