Zelio Smart Relay PLC Controller

HMI screen recording from my IPhone

We use Schneider Zelio SR3B101BD and the Schneider Zelio SR3B261BD for our small PLC automation and control projects requiring  a Modbus networking application.

The above image shows one of our  Schneider Zelio SR3B101BD Smart Relay PLC programmable logic controllers with a dedicated Schneider  Zelio  24VDC 1.2A PSU power supply and SR3XT43BD  five I/O analog add-on card.

This is the smallest PLC controller we use. It can be expanded to accommodate a network card and one additional I/O card should the need arise in the future to add additional inputs and outputs.
