Functional characteristics

High-speed counting

Supports an input frequency up to 1 MHz, suitable for counting and speed measurement of high-speed rotating equipment such as servo motors and stepper motors.

It provides counter, rate measurement and encoder modes to meet the needs of different application scenarios.

Flexible configuration

Users can perform module configuration and debugging through RSLogix 5000 or other compatible software.

Supports Preset and Rollover tags for setting the preset value and reset function of the counter.

Support the Period Rate and Continuous Rate modes, allowing users to dynamically adjust the Settings of the counter at runtime.

Output control

It provides 4 output ports, each of which can be independently controlled. It is suitable for outproducing switch signals (such as control relays, indicator lights, etc.).

The output delay time is 20 μs (nominal value) /50 μs (maximum value) from turn-off to turn-on, and 60 μs (nominal value) /300 μs (maximum value) from turn-on to turn-off.

The rated output current of each port is 20 mA (within the range of 5V) or 1.0 A (within the range of 12/24V).

Strong anti-interference ability

The Σ-Δ analog-to-digital converter and optocoupler isolation technology are adopted to ensure stable operation in industrial noise environments.

Supports differential input and high-speed differential input, suitable for high-noise environments.

Remote rack support: It can be connected to the remote rack via the 1756-CNB/CNBR module to achieve the expansion of the distributed control system.

Application scenarios

Industrial automation: Applicable to industrial automation systems that require precise counting and speed measurement, such as CNC machine tools, packaging machinery, printing machinery, etc.

Servo and stepper motor control: It is used to measure the rotational speed and position of servo motors and stepper motors to achieve closed-loop control.

Encoder interface: Supports signal acquisition for incremental encoders (such as Allen Bradley 845 encoder) and photoelectric sensors (such as Allen Bradley 10,000 series).

Process control: It is used to measure and control parameters such as flow rate, speed and position in industrial processes.

Safety control: Used in conjunction with the SIL2 safety level module, it is suitable for safety-critical applications.
