PLC selection memo — DVP20SX211S
The Delta DVP20SX211S is a DVP-SX2 2nd Generation Analog I/O Slim PLC, configured as an S-TYPE Main Processing Unit with 20 I/O points. The DC input variant is H TYPE, meaning it accepts high-speed sink/source DC signals typical for encoder or proximity sensor interfaces on a compact machine cell. At 20 I/O, this unit fits applications where analog loop control (temperature, pressure, flow) coexists with discrete logic on a single backplane, without needing a separate analog expansion module.
