Function

Analog input processing

Supports 16 single-ended or 8 differential inputs, which can be configured as voltage (1-5V DC, 0-5V DC, -5 to +5V DC, -10 to +10V DC, 0-10V DC) or current (4-20mA, 0-20mA, -20 to + 20mA) inputs.

It offers 12-bit resolution (with signed bipolar range), converts analog signals to four-bit BCD or 12-bit binary values, and scales to ±9999.

Block Transfer programming

Communicate with the PLC-5 processor using Block Transfer Write/Read (BTW/BTR) instructions to handle analog data and configure parameters.

Supports real-time sampling (RTS), digital filtering (noise cancellation), engineering unit scaling and data format selection.

High flexibility

The channel can be independently configured to support the measurement of various process variables such as pressure, liquid level, flow rate, temperature, speed, vibration, pH, etc.

The default user configuration provides predictable fault responses when communication is interrupted, ensuring security and system stability.

Isolation and Protection

Provide electrical Isolation (Opto-electrical Isolation) to protect the system circuits from the influence of electrical transients.

The input filtering function reduces electrical noise and ensures signal quality.

Installation and Diagnosis:

Single-slot module, installed on the 1771 I/O rack (except for the leftmost slot), uses the 1771-WG wiring arm for convenient wiring and maintenance.

The front panel is equipped with green RUN and red FAULT indicator lights for convenient status monitoring.

Application scenarios

Industrial Automation

Process control: Measures process variables such as pressure, liquid level, flow rate and temperature, and is applicable to industries such as petrochemical, pharmaceutical and food processing. For example, connect a pressure transmitter (4-20 mA) to monitor the pipeline pressure.

Environmental monitoring: Interface temperature sensors or pH meters, used in environmental control systems (such as water treatment plants).

Mechanical condition monitoring: Measuring vibration or displacement to monitor the health status of equipment.

Traditional system maintenance

It is used for maintaining or upgrading old systems based on PLC-5 and extending the lifespan of existing equipment. It is commonly found in power, manufacturing or heavy industry.

Cooperate with other PLC-5 modules (such as 1771-OZL) to construct an integrated control system.

Distributed control: Communicate with the PLC-5 controller through the Remote I/O or ControlNet network, suitable for distributed I/O applications in large factories.

Mixed-signal processing: In scenarios where multiple signal types (voltage/current) are required, it offers flexible channel configuration to reduce module demands.
