Physical Characteristics and Installation
This module weighs approximately 0.65 kg and fits into any S5 standard rack. Its dimensions measure 250 mm x 25 mm x 210 mm, which occupies one single-width slot. First, slide the 6ES5470-7LA12 into a free slot on the S5 rack. Then, connect the external 24V DC supply to the front connector. Finally, wire your field devices to the screw terminals.
Channel Configuration and Output Ranges
Each channel supports both voltage and current output types. You can independently configure every channel for your specific application. For voltage outputs, the module delivers 0 to 10V or ±10V. For current loops, it provides 0 to 20 mA or 4 to 20 mA. The 12-bit resolution ensures precise analog control.
Power Requirements and Isolation
The 6ES5470-7LA12 draws its logic power from the 5V DC backplane bus. However, it also needs a separate 24V DC supply for the analog circuits. This dual-power design provides channel-to-channel isolation. Consequently, you avoid ground loops when connecting multiple field devices.
