Product Introduction

The HK-MXB-0320 in the MX-Basic series is an EtherCAT industrial Ethernet bus interface that integrates a mixed I/O module for digital input and output. It can provide an ideal 16 channel industrial field 24V NPN/PNP digital logic input signal for higher-level EtherCAT master station controllers, and provide safety protection for current limiting and electrical isolation of the captured signals.
At the same time, HK-MXB-0320 can also convert the command signal issued by the main station controller into a 16 channel NPN/PNP industrial 24V digital logic signal output, with a maximum driving current of 0.5A/CH, which can be used to drive relays, indicator lights, and digital logic signals.
HK-MXB-0320 is divided into two models: HK-MXB-0320-1100 and HK-MXB-0320-2200. HK-MXB-0320-1100 is a PNP type 16 channel digital input and 16 channel digital output module, and HK-MXB-0320-2200 is an NPN type 16 channel digital input and 16 channel digital output module.
The 16 input and 16 output channels, EtherCAT communication interface, and power interface of HK-MXB-0320 all have corresponding LED indicators for quick observation and diagnosis of signal and command status.
