External digital input module ENA-DI
Characteristics:
ENA-DI is a digital inputs option for ENA500 power quality analyzer. Digital inputs are sampled synchronously with analog inputs of ENA500.
External digital input module ENA-DI can handle 16 or 32 digital inputs (ENADI16 or ENADI32 model). The sampling frequency per digital input is 960S/s and it is synchronized with a sampling rate ,of voltage and current inputs, of 9600S/s.
ENA500 and ENA-DI are connected to each other by cable with a length of up to 100 meters. The cable is used for data communication and power supply of ENA-DI. Each digital input has two input ranges for logical 1 (UL=16V-24V and UH=45V-250V). Digital inputs are isolated each from other.
