Description

Emerson  1C31116G05  Analog input module

Electrical characteristics
Input channels: Typically, it supports 16 single-ended input channels or 8 differential input channels, capable of simultaneously collecting multiple analog signals.
Signal type:
Voltage input: Supports multiple ranges, such as 0-10V DC, ±10V DC, ±1V DC, etc.
Current input: Commonly 4-20mA, 0-20mA, ±20mA, etc.
Other types: Some models may support thermal resistance (RTD) or thermocouple input (specific specifications need to be confirmed).

Input impedance:
Voltage input: Usually ≥10MΩ (high impedance, reducing the impact on the signal source).
When current is input: Typical value ≤250Ω (low impedance, ensuring accurate signal acquisition).

Accuracy and resolution:
Accuracy: ±0.1% or higher (depending on the range and environmental conditions).
Resolution: Usually 12 bits or 16 bits, providing high signal quantization accuracy.

Functional characteristics
Multi-signal compatibility: Through software configuration, it can flexibly support various types of analog signals without the need to replace hardware.
Electrical isolation: Electrical isolation (such as 500Vrms) is provided between channels and between input/output to prevent interference and fault spread.
Self-diagnostic function: Real-time monitoring of module status, supporting fault alarm (such as input disconnection, over-range, etc.).
Hot-swappable support: Supports plugging and unplugging while powered on, facilitating online maintenance and replacement, and reducing system downtime.
Communication interface: Usually communicates with the Ovation controller through the backplane bus, and some models support protocols such as Modbus RTU.
