40-ch isolated digtial input32 bit counter rs485 modbus rtu

S5302 Ethernet digital input module has total 40 channels isolated wet contact or dry contact or open-collector input, input channel 1 to 24 also can work as 32-bit counter input, the maximum frequency is 500Hz for total 24 channels and 5000Hz for only one channel.S5302 can connect to PC through  RS485 port, serial port support modbus protocol. All these communication port has static, over current, over voltage protect.  

Highlights:

l        RS485 with MODBUS protocol can connect up to 254 device

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 40 channels, improve frequency for small count input

l        Surge-protected Rs485 ensure reliability

l         A lot of spare FLASH can be used to store user's parameters

l         DIN support available

Wiring Diagram _ RS485

Dry contact input, relay contact

S5302 has 2 group input,input 1 to 24 and input 25 to 40.Each input has a jumper to config the corresponding group input work in DRY contact mode or WET  contact mode. The jumper inside the case and default is WET contact.DGND is the common for dry contact input1 to 40. 

Wet contact input, 0-36VDC

S5302 has 2 group input, input 1 to 24 and input 25 to 40.Each input has a jumper to config the corresponding group input work in DRY contact mode or WET contact mode. The jumper inside the case and default is WET contact. DVCC1 is common input for input I1 to I24, DVCC2 is common input for input I25 to I40. Never connect anything to DGND in WET contact input mode.

Power supply

       24VAC: power supply positive input, has reverse protection, accept AC and DC input

-           : Power supply negative input

RS485 Port

        B: Connect to B of RS485

        A: Connect to A of RS485

        R: Connect to GND of RS485 if necessary

 Inputs

DVCC1: Power source input for digital input 1 through 24

I1 ~ I24: Digital input channel 1 through 24

DVCC2: Power source input for digital input 25 through 40

I25~I40: Digital input channel 25 through 40

DGND: common for digital input 1 through 40, available in dry input mode
