CANopen is one kind of the network protocols based on the CAN bus and mainly used for embedded network of machine control, such as industrial machine control , aircraft engines monitoring, factory automation, medical equipments control, remote data acquisition, environmental monitoring, and packaging machines control, etc.
CAN-2084C module follows the CiA-301 version 4.02. CAN-2084C has passed the validation of the CiA CANopen conformance test tool. Therefore, you can use it with standard CANopen master easily by applying the EDS file. The CAN-2084C is a 4/8-channel Counter/Frequency module that provides “Up Counter”, "Frequency”, “Up/Down Counter”, “Dir/Pulse Counter” and “A/B Phase Counter” modes. It provides a variety of measurement applications, such as measuring a number of time-related quantities, counting events or totalizing and monitoring position with quadrature encoders. In addition, a digital filter is used to eliminate the effects of noise. By owing to the CANopen masters of ICP DAS, you can quickly build a CANopen network to approach your requirements.

TTL Input Level
Logic Level 0: 0 to +0.8 V
Logic Level 1: 2 to +5 V
Minimum Pulse Width
1 Hz ~ (typically) 250 kHz for both counter and frequency mode, where 250 kHz is calculated as follows:
supposed that the duty cycle = 50%, by referring to the Minimum Pulse Duration of the High Level, the pulse period will be 2 µs x 2 = 4 µs, which is 250 kHz as a maximum.
Refer to the Minimum Pulse Duration of the High Level, the maximum frequency is highly affected by the duty cycle
