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

Wiring Diagram _ RS485
Dry contact input,relay contact
Digital input 1 through 24 can be dry contact input, DGND is the common for dry contact input, there are a jumper inside the board, please jump it to DRY.
Wet contact input, 3-40VDC
Digital input 1 through 24 can be wet contact input, there are s jumper inside the board, please jump it to WET when your input type need external power supply. DVCC is common input for all inputs.Never connect anything to DGND in WET contact input mode.
Isolated open-collector output
O1 through O16 is isolated open-collector output, can dry relay coil .OGND is common for external power supply.
PINs and LEDs
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 for RS485
Inputs
DVCC: Power source input for digital input 1 through 24,wet contact input available
I1 ~ I24: Digital input channel 1 through 24
