Function

Fast analog signal processing: It offers 2 fast analog input channels and 2 current output channels, suitable for processing rapidly changing analog signals such as pressure or flow.

Flexible signal selection: The input channels support 0-10V DC or 0-20mA signals, which can be configured channel by channel to adapt to various sensors and devices.

High resolution and precision: 12-bit input and 14-bit output resolution, combined with high precision, ensure reliable data conversion and control.

Noise suppression: The input channel is equipped with an internal filter to effectively suppress high-frequency noise, making it suitable for noisy industrial environments.

Compact design: Single-slot module, integrated input and output functions, saves rack space, suitable for space-constrained applications.

Fast response control: Supports a fast response control loop, with an output step response time of 2.5ms, suitable for dynamic adjustment applications.

Strong compatibility: Compatible with SLC 500 fixed (such as 1747-L20, L30, L40) and modular hardware, and supports expanded rack configuration.

Application scenarios

Industrial automation control: Used in the SLC 500 system, it processes rapidly changing analog signals and is suitable for real-time monitoring and control in production lines, such as injection molding machines and hydraulic presses.

Process control: In pressure control applications (such as hydraulic systems or pneumatic systems), the rapid input channel collects sensor data, and the output channel controls the actuator (such as a 4-20 mA control valve) to achieve closed-loop control.

Equipment monitoring: It collects rapidly changing analog signals (such as temperature, flow rate, and liquid level) for real-time data recording and equipment status monitoring, and is applied in the manufacturing industry.

High-precision regulation: By controlling the actuator through high-resolution output (such as 14-bit output), it is suitable for applications that require precise control, such as flow control valves or speed regulation.

Special metering applications: Supports total quantity measurement, metering and other functions, suitable for metering systems that require rapid response, such as filling equipment or packaging lines.
