S5138 is a high quality and low cost analog data acquisition module with 8 universal analog inputs. Each input can be 0-5V,0-10V,0-20mA,thermistor,dry contact, open-collector input,6 isolated digital input and 16 channels isolated open-collector digital output. The digital input can be dry contact, wet contact and open-collector, each input also can be 32-bit counter.S5138 has RS485 and rj45 two type interface,rs485 support standard Modbus RTU protocol and RJ45 support Modbus Tcpip protocol.It can easy integrate with PLC and labview with standard Modbus/Modbus Tcpip protocol Highlights: l Surge-protected analog inputs with 12-bit resolution and 100k sample speed l Input can be any combination of 0-5V,4-20mA,0-10V,NTC 10K thermistor, open-collector and dry contact l The channel number is configurable, can be set up from 1 channel through 8 channels, for analog input and set up from 1 to 6 for digital input, improve sample rate for small count input l Isolated digital inputs can be configured as counter input, total 32 bits,1000Hz l Total 16 channels isolated open-collector digital output l Standard ModBus TCPIP protocol,easy work with PLC l Standard ModBus protocol allows for up to 254 unique devices on one RS485 network l A lot of spare FLASH can be used to store user’s parameters l Can update your firmware via ISP through RS485 network, can provide any hex file to help you finish some logic control l DIN support available Application: ü Remote data acquisition ü Process monitoring ü Industrial process control ü Energy management ü Supervisory control ü Security systems ü Laboratory automation ü Building automation ü Product testing ü Direct digital control Technical data: Analog Input Resolution--------------------------------------------------------------------------------12-bit Analog Input Channel Number------------------------------------------------------------------------------8 Analog Input range----------------------0-5V,0-10v,0-20mA, thermistor, dry contact,open-collector Analog Input Protection---------------------------------------------------------------------Lightning,static Analog Input Accuracy---------------------------------------------------------------------------------±0.1% Analog Input Zero drift-----------------------------------------------------------------------------±3uV/℃ Analog Input Sample Rate-----------60 sample/second(8 channels),900 sample/second(1 channel) Digital Input Channel Number----------------------------------------------------------------------------- 6 Digital Input Range-------------------------------------------------------------------------------+4V~+36V Digital Input Signal----------------------------------------------wet contact, dry contact, open-collector Digital Input Counter Frequency-------------------------------100Hz@6channels;1000Hz@1channel Digital Input Counter Length---------------------------------------------------------------------------32-bit Output channel number-----------------------------------------------------------------------16 Output signal---------------------------------------------------------------------open-collector Output current----------------------------------------------------------------maximum 40mA Output BUS----------------------------------------------------------------------------------Ethernet/RS485 RS232/RS485 protocol--------------------------------------------------------------MODBUS/RTU Ethernet protocol------------------------------------------------------------------MODBUS/TCPIP Output Protection-----------------------------------------------------------------------------Lightning,static Power input----------------------------------------------------------------------------------15~24V(AC/DC Power consumption------------------------------------------------------------------------------------<0.6W Ambient temperature: Operation-------------------------------------------------------------------------- -20~85℃(-4~185℉) Storage---------------------------------------------------------------------------------------- -40~125℃(-40~257℉) Ambient humidity-----------------------------------------------------------------------------------------------10%~90%RH Material,enclosure-----------------------------------------------------------------------Flame proof plastic Enclosure rating--------------------------------------------------------------------------------------------IP31 Colour----------------------------------------------------------------------------------------------White/Black Size---------------------------------------------------------------------------------------------115*90*43 mm Wiring diagram and description:
