The 1756SC-IF8H module is an PLC/Spectrum Controls analog I/O module that is available through the 1756 ControlLogix product family. The ControlLogix components like this one are extremely reliable and they allow communication through several different networks. The ControlLogix parts are mostly chassis-based and are easy to maintain. The most popular networks that are used for communication between these components are the ControlNet and EtherNet/IP networks. Every ControlLogix component is made according to international industrial regulations and meets all the applicable standards. The 1756SC-IF8H analog I/O module includes certifications from the C-Tick, CE, CSA, cULus, and FM standards. The controllers used with this module require either a removable terminal block (RTB) or wiring interface module (IFM) for all the field-side wiring.
The 1756SC-IF8H analog I/O module is enabled for communication through HART networks and it requires only one slot for installation, like other components of similar dimensions. The unit operates in the current mode and it features the feed-through AIFM type. The 1756SC-IF8H module has 8 available channels for either input or output. It should be mentioned that each channel comes with three terminals. The accuracy of the unit is better than 0.1% and it uses the IEEE (32-bit, floating point) data format. The resolution of the module is from 16 to 21 bits and its current rating is 0 to 20 milliAmps or 4 to 20 milliAmps. In regard to environmental conditions, the unit features a relative humidity range of 5 to 95% (non-condensing) and an operating temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit).
