Zelio Compact relay 20 inputs outputs - Power supply 100 to 240Vac The Schneider Electric SR2B201FU intelligent relay is a simple to implement programmable logic controller. It is easily programmed using the Zelio Soft 2 software and its intuitive interface. Easy to install, this Zelio Logic Relay mounts on a standard symmetrical DIN rail. All PLC inputs and outputs are equipped with a screw terminal block. The Zelio SR2B201FU reference is a Compact model, which means that it cannot be associated with an input/output expansion module. If you are looking for a scalable Zelio relay, prefer the Modular model which can accommodate different extension modules. This Zelio automaton is equipped with a clock and a digital display screen. Supply voltage: 100 to 240Vac Total inputs and outputs: 20 Digital inputs: 12 of which analog inputs 0-10V: 0 Relay outputs: 8 Transistor outputs: 0 Backlit display screen: Yes Clock: Yes
