Festo
The Festo part number 549044 is an industrial component featuring an AS-Interface DC operating voltage range of 26.5 V to 31.6 V with a nominal operating voltage of 26.5 V and residual ripple <= 20 mVss, alongside a DC load voltage range of 21.6 V to 26.4 V with 4 Vss residual ripple. This device supports up to 4 inputs and 4 outputs, accommodating a maximum of 4 solenoid coils, 4 single-solenoid valves, or 2 double-solenoid valves, and includes DIL switch control elements, an M12x1 4-pin socket and plug fieldbus interface, and 1 slave per device. It provides device-specific diagnostics for undervoltage, peripheral errors, and short circuit or overload of inputs, features reverse polarity protection for all electrical operating voltage connections, operates at any mounting position, and accepts switching levels of signal 0 at <= 5 V and signal 1 at >= 11 V with permissible voltage fluctuations of +/- 10%.
