Data Acquisition Modules, Data Acquisition Modules S142

Data Acquisition Modules, Data Acquisition Modules S142 Introduction : The DAM142 is for monitoring 24 digital input( can be used as pulse counter) . It supports Modbus RTU Protocol over RS485 serial port. Powered up by 10~ 30VDC. The DAM142 is used widely in industrial automation control systems. E.g.: Base Transceiver Station, diesel generator rooms, engine room, transformer substations, telecommunication equipment rooms, power supply systems and so on. The DAM142 is an industrial class, high reliability, low-power consumption, high stability and high precision data acquisition module. The DAM142 with fire retardant shell, standard 35mm DIN rail makes it easy to install in fields. Mainly Features: 24 digital input, Dry contact or Wet contact( logic: 0~ 0.5V or NC= 0, + 3~ 30V or NO= 1, input voltage range: 0^ 30V, Input Max. voltage range: -10^ 40V) , can be used as pulse counter input: counter sampling frequency: 1KHz, impulse width of high or low level must > 1mS, Max. counter value is 4 bytes: FFFFFFFFH; Wide range power supply with reverse polarity connection protection; Modbus RTU Protocol; ESD Protection circuit for RS485 serial port; Using industrial-grade chips; Built-in watchdog ensure it reliability; Lightning protection ensure it stability; LEDs for status indication makes it easy to program in filed.
