Sixteen temperature points do not need sixteen separate acquisition devices. HJ2009K16 is an expansion module with 16 thermocouple input channels for HJ5200 and HJ3200 remote-I/O systems. It accepts K, J, T, S, N, E, B and R thermocouple types, communicates through LINK-TX/LINK-RX, runs from 9–28VDC and mounts on DIN rail. That combination makes it worth reviewing for furnaces, heating equipment or process machinery with dense temperature monitoring. Before building the channel list, confirm the parent remote-I/O series, thermocouple type at every point, temperature range, compensation and grounding requirements.
