4-Channel Isolated Analog Input Module
A Spectrum Controls analog input module designed for use with the Allen-Bradley SLC 500 platform, supporting individually configurable current and voltage inputs.
4 Isolated Channels Current / Voltage 16-Bit Resolution
01 / PRODUCT INTRODUCTION
Flexible Analog Signal Acquisition
The 1746SC-INI4VI monitors up to four isolated analog current or voltage inputs. Each channel can be configured independently, allowing different signal types and ranges to be used within one module. This flexibility can help reduce the need for separate input modules when a control system handles mixed analog signals.
Key Technical Specifications
Parameter Specification
Module Type Isolated analog input
Number of Channels 4 differential, individually isolated channels
Current Input Ranges 0–20 mA / 4–20 mA
Voltage Input Ranges 0–5 V / 1–5 V / 0–10 V / ±10 V
Resolution 16 bits
Backplane Current 550 mA at 5 VDC, typical
Chassis Position Any 1746 I/O slot except slot 0
Input ranges are configurable by channel. Confirm the intended signal type and range for each channel before commissioning.

02 / INPUT CONFIGURATION
One Module, Multiple Signal Types
The 1746SC-INI4VI is suitable for applications where current and voltage signals need to be acquired through a compact SLC 500 I/O arrangement. Each channel can be assigned its own supported input type and range, so the selected configuration should match the field transmitter or instrument connected to that channel.
CURRENT INPUT
0–20 mA
4–20 mA
For compatible current-output field instruments and transmitters.
VOLTAGE INPUT
0–5 V / 1–5 V
0–10 V / ±10 V
For compatible voltage-output sensors and signal conditioners.
03 / SYSTEM INTEGRATION
Designed for the SLC 500 I/O Environment
The 1746SC-INI4VI is intended for a 1746 I/O chassis and can be installed in an available I/O module slot other than slot 0. Its four isolated input channels allow different compatible analog signals to be handled within one module. Before installation, review the chassis power budget, field wiring, channel configuration and controller-side data handling.
CHASSIS
Check the available I/O slot and power capacity.
FIELD WIRING
Match the wiring to each selected input type.
CONFIGURATION
Verify channel ranges and processor data mapping.
04 / BEFORE YOU ORDER
Four Details Worth Confirming
01 Full part number: Confirm 1746SC-INI4VI and any suffix or revision marking.
02 Input mix: List the current or voltage range required by each channel.
03 Chassis capacity: Check the 5 VDC backplane current budget and available slot.
04 Application details: Confirm controller model, quantity, destination and required date.

05 / FREQUENTLY ASKED QUESTIONS
1746SC-INI4VI · Buyer Questions
Q1. Can 1746SC-INI4VI read current and voltage signals at the same time?
Yes. The module supports current and voltage input types in different channel combinations. Each channel must be configured for the signal type and range used by its connected field device.
Q2. What should be checked if a 1746SC-INI4VI channel gives an incorrect reading?
Check the selected channel range, wiring polarity, signal type and field-device output. Also verify the processor's data scaling and channel configuration before concluding that the module is faulty.
Q3. Does 1746SC-INI4VI use the same chassis power budget as a standard SLC 500 analog module?
Do not assume the current requirement is identical. The 1746SC-INI4VI has a typical backplane current requirement of 550 mA at 5 VDC. Check the available power supply capacity and the total chassis load before installation.
Q4. Can 1746SC-INI4VI be installed in slot 0 of a 1746 chassis?
No. The module is intended for an available 1746 I/O module slot other than slot 0. Confirm the chassis layout and the intended installation position before fitting the module.
Q5. What information is needed to match a replacement 1746SC-INI4VI?
Provide the complete catalog number, revision marking, SLC 500 chassis details and the required input configuration. If possible, include a photo of the installed module label and terminal wiring for a more accurate check.
