Spectrum 1746SC-INO4VI SLC 500 4‑Ch Isolated Analog Output Module

Spectrum 1746SC-INO4VI SLC 500 4‑Ch Isolated Analog Output Module

The SPECTRUM 1746sc ino4vi module is a high-performance, four-channel isolated analog output module that is intended for Allen-Bradley SLC 500 PLC systems. It is capable of delivering precise current or voltage outputs in the most demanding industrial environments. The four channels can be individually configured for either current or voltage, enabling the combination of output types per channel for the highest degree of flexibility in a single, compact module.

This module provides 16-bit resolution and a variety of programmable ranges, such as 0–20 mA, 4–20 mA, 0–21 mA, 0–5 V, 1–5 V, 0–10 V, and ±10 V. This capability enables the precise representation of process variables and the seamless operation of analog devices such as drives, valves, and actuators. It effectively eliminates crosstalk and safeguards the processor from electrical noise and transients that are common in congested control panels, thanks to the built-in 750 VDC channel-to-channel and field-to-backplane isolation.

The 1746SC-INO4VI is engineered to facilitate seamless integration with RSLogix 500 and standard SLC 500 racks. It offers software configuration, programmable output limits, and user-selectable safe states to ensure that outputs are driven to a predetermined value during malfunction conditions. The absence of the necessity for field calibration and the consistent performance over time are guaranteed by the continuous onboard temperature compensation, which maintains accuracy from 0 to 60 °C.

A channel update time of approximately 33.7 ms for all four channels and a typical step response of approximately 1 ms to 95% of full scale enable responsive control in fast-moving processes. This module is ideal for use in severe process, factory, and utility environments where reliability and safety are essential. It has been designed with industrial certifications, including UL/cUL, CE, and Class I, Div 2 hazardous location ratings.

Technical specifications

Benefits:

1. Gives you four completely separate analog output channels, which stops crosstalk and noise from getting in the way in industrial situations with more than one feed.
2. One module can be set up to output either current (4–20 mA) or voltage (0–10 V) on each channel, which cuts down on the number of panels and inventory needed.
3. 16-bit high resolution gives valves, motors, and actuators more accurate control signals than 12-14 bit equivalents, which makes the process more accurate.
4. 750 VDC channel-to-channel and field-to-backplane isolation keeps high-voltage transients and ground loops from getting to the PLC backplane. These are popular in marine and power plants.
5. Built-in continuous temperature correction (0–60°C) keeps the output accurate without needing to be recalibrated in the field, which cuts down on downtime in tough conditions.
