OVATION Emerson 1C31199G04 High-Density Analog Input Module

Product Description

The Emerson OVATION 1C31199G04 is a 16-channel analog input module designed to acquire voltage and current signals in an Ovation distributed control system. It supports multiple input ranges, including 0-20 mA and 4-20 mA current signals, as well as several voltage ranges. Furthermore, its 16-bit resolution, signal isolation and diagnostic capabilities support accurate analog signal monitoring.

Input Channels and Signal Configuration

The 1C31199G04 provides 16 single-ended analog input channels. It accepts both voltage and current signals, allowing the module to handle different field signal requirements within the same hardware configuration.

• 16 single-ended input channels
• Voltage ranges: +/-10 V, +/-5 V, +/-1 V and +/-0.5 V
• Current ranges: 0-20 mA and 4-20 mA
• Configurable input ranges
• Configurable scan rate per channel

For example, the module can acquire standard 4-20 mA process signals or voltage signals from compatible field instruments. Therefore, the selected input range must match the connected signal type.

Resolution and Measurement Performance

The module uses 16-bit resolution to convert incoming analog signals into digital values for the control system. Its typical accuracy is +/-0.1% of full scale, providing a defined measurement tolerance across the selected input range.

Furthermore, its common-mode rejection of more than 120 dB and normal-mode rejection of more than 60 dB help reduce electrical interference during signal acquisition.

Input Impedance and Electrical Isolation

The input impedance depends on the selected signal type. Voltage inputs have an impedance greater than 1 Mohm, while current inputs use a 250-ohm impedance.

In addition, the module provides two specified isolation ratings: 500 VAC between channels and 1500 VAC between channels and the system. These ratings define the electrical isolation boundaries for field signal acquisition.

Frequently Asked Questions

Q: How many analog input channels does the Emerson 1C31199G04 provide?

A: It provides 16 single-ended analog input channels. Each channel supports configured voltage or current input ranges.

Q: Does the 1C31199G04 support both 4-20 mA and voltage signals?

A: Yes. It supports 4-20 mA and 0-20 mA current signals, along with four voltage ranges from +/-0.5 V to +/-10 V. Select the appropriate input range according to the connected field signal.

Q: What is the isolation rating of the 1C31199G04?

A: The specified isolation is 500 VAC between channels and 1500 VAC between channels and the system. These ratings describe different electrical isolation boundaries and should not be treated as interchangeable.
