24 Channels Isolated Digital Input and 16 Channels Isolated Digital Output RS485 Modbus Rtu

S5301 digital input/output module has total 24 channels isolated wet contact or dry contact or open-collector input and 16 channel isolated open-collector output, Each input channel also can work as 32-bit counter input, the maximum frequency is 500Hz for total 24 channels and 5000Hz for only one channel, each output can drive relay directly.S5301 can connect to PC through RS485 port with modbus protocol. All these communication port has static, over current, over voltage protect.   Highlights: l  RS485 with MODBUS/RTU protocol l  Isolated digital inputs can be configured as counter input, total 32 bits,5000Hz l  Can measure frequency from 0 to 1000Hz,the resolution is 0.1Hz l  Accept reed and hall sensor output from water meter or other meters l  Static and lightning protection for each input l  The input channel number is configurable, can be set up from 1 channel through 24 channels, improve frequency for small count input l  Isolated open-collector output can drive power relay directly l  A lot of spare FLASH can be used to store user’s parameters l  DIN support available l  Black,blue,white color case available Application:
