The DAM144 is for controlling 24 triode drivable digital output(50V/100mA,can be TTL or Pulse output). It supports Modbus RTU Protocol over RS485 serial port. Powered up by 10~30VDC. The DAM144 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 DAM144 is an industrial class, high reliability, low-power consumption, high stability and high precision data acquisition module. The DAM144 with fire retardant shell, standard 35mm DIN rail makes it easy to install in fields. Mainly Features : Ø 24 drivable digital output(triode, not relay,50V/100mA), can be setup as TTL output or Pulse output(impulse width 0.1~20S); Ø Wide range power supply with reverse polarity connection protection; Ø Modbus RTU Protocol; Ø ESD Protection circuit for RS485 serial port; Ø Using industrial-grade chips; Ø Built-in watchdog ensure it reliability; Ø Lightning protection ensure it stability; Ø LEDs for status indication makes it easy to program in filed.
