Block PLC has analogue I/O built in as standard

Hitachi says it has been able to provide high specification analogue I/O into its standard range of EC brick PLCs without increasing unit size or introducing cost penalties.

The EC series now incorporates two analogue inputs and one analogue output. The two analogue inputs have a resolution of 11 bits, and the output has a resolution of 8 bits. All analogue I/O can be selected independently for 4-20mA or 0-10V DC, and the 24V digital inputs can be user configured for NPN or PNP input.
