Function

Multi-type signal input

Supports multiple voltage (-10 to +10 VDC, 0 to 10 VDC, 0 to 5 VDC, 1 to 5 VDC) and current (4 to 20 mA, 0 to 20 mA, -20 to +20 mA) inputs, flexibly adapting to different sensors and devices.

Supports single-ended or differential input configuration to reduce noise interference.

High precision and resolution:

The 12-bit resolution (4096 stops) ensures precise signal acquisition and is suitable for high-precision measurement.

The accuracy is ±0.1% (voltage) or ±0.2% (current), meeting the requirements of industrial control.

Channel isolation

Provide 1000 VDC isolation between channels and input to the backplane to prevent signal interference and ground loops, and improve system reliability.

Rapid data acquisition: The conversion time per channel is approximately 5 ms, and the complete scan of 8 channels takes about 40 ms, making it suitable for real-time monitoring and control.

Overvoltage protection: Built-in overvoltage protection (voltage ± 30VDC, current ± 30mA), protecting the module from accidental overload or incorrect wiring.

Modular design: Occupies 1 I/O rack slot, uses 1771-WH wiring arms to simplify wiring, and supports continuous removal/insertion without disconnection (RIUP, power off required).

Compatible with PLC-5 processors (such as 1785-L80C) and power modules (such as 1771-P5).

Diagnosis and Configuration

Support configuring the input range and filtering parameters through RSLogix 5 or Studio 5000 Logix Designer.

Provide status data, report the validity of input signals, and facilitate fault diagnosis.

Application scenarios

Process control: In the chemical, oil and gas, or pharmaceutical industries, analog signals such as temperature, pressure, flow rate, or liquid level (such as 4-20 mA sensor signals) are collected for PID regulation or process monitoring.

Manufacturing plants: In automotive manufacturing, food processing or electronic assembly production lines, monitor sensor data (such as voltage output sensors) to support quality control or equipment status monitoring.

Energy management: In power distribution or renewable energy systems, voltage or current signals are collected (such as in battery management systems, transformer monitoring) to ensure the stable operation of the system.

Environmental monitoring: It is used in environmental control systems to collect analog signals such as temperature, humidity, and gas concentration, and is suitable for HVAC or pollution control applications.

Mechanical automation: In packaging machinery or material handling systems, monitoring analog sensors (such as displacement and speed sensors) supports precise control and feedback.
