Function

Flexible input selection: The 4 channels can be independently configured as voltage (-10 to +10 V) or current (-20 to +20 mA), and can be set through the DIP switch on the circuit board, supporting a variety of sensors and transmitters.

High-resolution conversion: 16-bit resolution, using Delta-Sigma modulation, providing high-precision analog signal conversion, with an output range of -16,384 to +16,384 (current) or -32,768 to +32,767 (voltage).

Data processing: Supports scaling algorithms, which can convert the original analog data into engineering units, facilitating processing by the controller.

Fast update: All channels update in parallel with an update time of 512 µs, suitable for dynamic monitoring applications.

Diagnosis and Configuration: Configuration is carried out through the RSLogix 500 software. The LED indicator light of the module status supports the monitoring of the operating status. The DIP switch allows on-site adjustment of the input type.

Compatibility: Compatible with SLC 500 fixed or modular hardware, can be inserted into 1746 racks, and seamlessly integrated with the processor.

Detachable terminals: Simplify wiring and module replacement, suitable for maintenance and debugging.

Application scenarios

Process control: such as water treatment and food processing, connecting pressure, temperature and flow transmitters, monitoring and controlling analog signals.

Industrial automation: Used in production lines to monitor sensor signals and support small and medium-sized automation systems.

HVAC system: Monitor environmental parameters and optimize control through analog input.

Manufacturing equipment: such as injection molding machines and packaging machines, collect simulation data to achieve precise process control.

Data acquisition: Integrated with the SCADA system, it collects data from analog sensors for real-time monitoring and recording.
