Cost-effective RS-485 Remote I/O Module: ADAM-4000
AD-ADAM-4000 series modules are compact, sensor-to-computer interface units designed for reliable operation in harsh environments. Built-in microprocessors independently provide intelligent signal conditioning, analog I/O, digital I/O, data display, and RS-485 communication through Modbus protocols. With RFID and USB technology, users have additional options for configuration and inspection, even when unpowered.
AD-ADAM-4100 series modules are robust data acquisition and control units supporting wider operating temperature, higher noise immunity and wide power input.

RS-485 Serial I/O:
ADAM-4000/4100 Series
The ADAM-4000/ 4100 series featuring rugged industrial-grade cases are specially designed for reliable operation in harsh environments.
Built-in microprocessors independently provide intelligent signal conditioning, analog I/O, digital I/O, data display, and RS-485 communication through Modbus RTU protocols.
