ADAM-4021-DE The ADAM-4000 series is a set of intelligent sensor-to-computer interface analog I/O modules containing a built-in microprocessor. They are remotely controlled through a simple set of commands issued in ASCII format and transmitted in RS-485 protocol.The 4000 series provide signal conditioning, isolation, ranging, A/D and D/A conversion, data comparison, and digital communication functions. Some modules provide digital I/O lines for controlling relays and TTL devices.Buy and compare our RS-485 I/O modules below.
