          PRODUCT DESCRIPTION

          1746-NO4I Analog Current Output Module

          Allen-Bradley 1746-NO4I is a four-channel analog current output module for SLC 500 controllers. It provides a normal 0 to 20 mA output range through 14-bit digital-to-analog conversion, using the SLC output data representation to command connected analog circuits.

          The four outputs update in parallel within 512 microseconds and reach 95% of a step change in 2.5 ms. Each output supports a resistive load up to 500 ohms and load inductance up to 100 microhenries. Backplane requirements are 55 mA at 5 V and 195 mA at 24 V; the documented external 24 V supply option is used only according to the module installation instructions.

          1746-NO4I SLC 500 Analog I/O Analog Current Output Module
          SYSTEM & REPLACEMENT CHECK

          Information needed before ordering

          Three direct checks to secure your system integration and minimize ordering risks.

          Information

          System integration Replacement check Manuals & support
          SYSTEM INTEGRATION

          Integrate 1746-NO4I within SLC 500 Analog I/O

          Configure 1746-NO4I in the SLC 500 rack with its four output words and the documented two's-complement representation. The module provides current outputs only; it does not add analog inputs or voltage outputs to the controller.
          Connect the current loops through the assigned terminal positions using the shielding and grounding method in the installation instructions. Keep loop resistance at or below 500 ohms and inductance at or below 100 microhenries, and preserve the distinction between field-to-backplane isolation and individual-channel isolation.
          Check the available 5 V and 24 V backplane capacities before operation. If the documented external 24 V option is used, follow the specified wiring and selector arrangement. Commission each loop with known output commands and compare the measured current with the intended scaling.

          Features:

          • Current output channels: 4
          • Normal output span: 0 to 20 mA
          • SLC 500 Analog I/O
          Use 1746-NO4I only within the documented SLC 500 Analog I/O arrangement and applicable installation instructions.
          INTERCHANGEABILITY

          Replace 1746-NO4I within SLC 500 Analog I/O

          For 1746-NO4I replacement, save the controller program and output scaling, then record terminal assignments and the 24 V supply arrangement. A voltage-output 1746 module or a mixed analog I/O module is not equivalent to this four-current-output unit.
          Place the connected process in a controlled state before removing the output module. Isolate the relevant power sources and inspect the terminal block, shield connections and current-loop loads; restoring an incorrect loop connection can produce an unintended analog command.
          After fitting 1746-NO4I, restore the original rack configuration and verify all four loops at representative low, mid and high commands. Confirm current direction, scaling, fault behavior and any required response timing before releasing the outputs to automatic control.

          Features:

          • D/A resolution: 14 bits
          • Output coding: 16-bit two's complement
          • Recorded connections and functional validation
          Use 1746-NO4I only within the documented SLC 500 Analog I/O arrangement and applicable installation instructions.

          Questions buyers ask about 1746-NO4I

          Direct answers about identity, compatibility, stock, warranty, payment and shipping.

          • Does 1746-NO4I supply voltage outputs as well as current?

            No. 1746-NO4I provides four analog current outputs with a normal span of 0 to 20 mA.

          • What loop resistance can 1746-NO4I drive?

            The maximum resistive load for a 1746-NO4I output is 500 ohms.

          • What is the 1746-NO4I analog step-response time?

            1746-NO4I reaches 95% of an output step in 2.5 ms under the documented conditions.

          • Are 1746-NO4I channels individually isolated?

            Do not infer individual-channel isolation from the 500 V DC field-to-backplane isolation specified for 1746-NO4I.

          • How much backplane power should be budgeted for 1746-NO4I?

            1746-NO4I requires 55 mA at 5 V DC and 195 mA at 24 V DC.

          • What should be checked after 1746-NO4I loop replacement?

            For 1746-NO4I, test all four loop currents against known output commands and confirm scaling and safe fault response.

          • Which spare-part photos are useful for a 1746-NO4I quotation?

            Supply the 1746-NO4I label, terminal-block arrangement and external-power configuration so the ordered module and required accessories can be checked.

          • Does a 1746-NO4I order automatically include a terminal block?

            The 1746-NO4I quotation should explicitly state terminal-block and accessory inclusion; the module number alone does not define supplied scope.
