The 1746sc-INI4I is a Spectrum Control unit featuring 4-channel isolated analog input current only. This unit is manufactured by Allen Bradley and classified under the SLC 500™ series. The module features a universal analog module for four channels, each of which channels has individually configurable channels ideal for voltage, current, thermocouple, RTD, and resistance. Note that with the 1746sc-INI4I, any combination of inputs is feasible and can be used simultaneously. The 1746sc-INI4I reduces the system cost by reducing or eliminating the need to have a dedicated analog input/output. The 1746sc-INI4I has a counter or a flow meter module that supports four single-ended counters and combines input pairs so as to create quadrature counters. The 1746sc-INI4I spectrum control allows for solutions that offer cost efficiency for the complex application requirements. In addition, the 1746sc-INI4I has high performance features with an increased channel density and versatile configuration options. The 1746sc-INI4I has an LCD display feature that supports numeric keypads and has the programmable function keys. The 1746sc-INI4I has 750 Volts DC with channel-to-channel isolation. It eliminates the need for expensive external isolators. For the 1746sc-INI4I, isolation reduces susceptibility to electrical noise and prevents cross-talk between channels and the ground loop problem.

For the 1746sc-INI4I, any combination of inputs is usable simultaneously and the 1746sc-INI4I is ideal for the OEMs and system integrators. The module reduces the need for a dedicated analog module through the use of one universal analog module. The 1746sc-INI4I allows for a simple configuration through the use of ladder register settings and jumpers. The 1746sc-INI4I is configurable for voltage, current, thermocouple, RTD, and resistance.
