The Siemens 6ES7321-1FH00-0AA0 is a SIMATIC S7-300 SM 321 digital input module with 16 isolated inputs for 120/230 V AC signals. It reads field devices such as pushbuttons, limit switches, proximity sensors, and relay contacts and reports their states to the S7-300 CPU over the backplane bus. The inputs are optically isolated from the backplane bus.
The module mounts on the S7-300 rail and requires a 1x 20-pin front connector (sold separately).
