The 6B50-1 / 6B50-2 is a digital I/O module from Analog Devices that can be configured individually and remotely reconfigured to suit a variety of sensor types and input ranges. It is used for remote data acquisition, machine monitoring, remote energy management and process monitoring and control applications.
The 6B50‑1 and 6B50‑2 are 24‑channel digital I/O boards designed for process monitoring, machine monitoring, remote energy management and laboratory data acquisition. They interface with the 6B Series signal‑conditioning modules and can be mixed on a 16‑channel backplane for high‑density applications.
Each board includes a microcontroller, non‑volatile memory for configuration, RS‑232C (6B50‑2) or RS‑485 (6B50‑1) serial communication, and selectable baud rates up to 19.2 kBaud. Power modules can switch up to 3 A, and the boards operate over an industrial temperature range of –25 °C to +85 °C.

Each 6B50‑1 or 6B50‑2 board provides 24 digital I/O channels that can be configured as inputs or outputs.
The 6B50‑2 uses an RS‑232C interface, while the 6B50‑1 communicates via RS‑485 on the 6B Series backplane.
The boards support software‑selectable baud rates of 300 k, 600 k, 1.2 M, 2.4 M, 4.8 M, 9.6 M and 19.2 M.
The modules are rated for operation from 0 °C to +70 °C and can be stored from –40 °C to +85 °C.
