The 1756-IF8H is an is an I/O module with an analog input and it has 8 channels. It belongs to the ControlLogix series. It is manufactured by Allen-Bradley. It has a single HART modem per module. The voltage and current ratings for the backplane is 5.1 Volts DC with 300 mA of current. The 1756-IF8H has a factory-set operating temperature in the range of 0 to 60 degrees Celsius. It has an input voltage range from -10 to +10 Volts and the input currents range from 0 to 20 mA and 4 to 20 mA. 3.21 Watts of voltage and 4.01 Watts of current is dissipated from the system.
The 1756-IF8H obtains A signal from the processing value transmitter and it changes the signal to specific values for the controller’s use. It has three data formats to choose from. It multicasts system status and fault information to the users’ controller with its channel data. There are three level of tags which show the details of the specific cause causing the faults in the device. For safety purposes, the 1756-IF8H comes with an underrange and overrange detection feature that detects if the module is operating against the set limits and prevents damage to the device. It has process alarms (when the module has exceeded the configured high or low limits), rate alarms (if the rate of change between input samples exceeds the trigger), different filters, and a single HART modem. It also has a wire-off detection facility which informs when a wire is disconnected from a channel or not.
