Features:
- Switches sixteen isolated transistor outputs for 24–60 V DC circuits.
- Handles documented channel currents from 5 mA to 0.5 A.
- Provides individual slow fuses and visible short-circuit indication.
The 457 designation and 4UA12 suffix together identify this high-voltage DC transistor version. Its 40 mm width and protection arrangement differ from nearby S5 output cards.
The module converts S5 process-image bits into solid-state field switching without using mechanical relay contacts.
Before exchange, inspect each connected load and record fuse locations, commons, enable wiring and channel numbers. Energize groups gradually while observing the fault indicator.
6ES5457-4UA12 availability is verified with its 24–60 V transistor and individual-fuse configuration.

- Drive isolated DC interface relays from a legacy S5 control sequence.
- Switch panel lamps and small actuators within the documented load limits.
- Restore individually protected output channels in an S5-155U machine rack.
- A red indication identifies a short-circuit condition affecting an output.
- Sixteen 1 A slow fuses provide individual channel protection.
- External faults must be cleared before a replacement fuse or module is energized.
- Channel current is specified from 5 mA to 0.5 A for the supported field supply.
- Lamp loading is limited to the documented 0.22 A maximum.
- Typical 5 V bus demand is 120 mA while module dissipation is stated at 13 W.
- The 40 mm module width must be available in the target S5 rack position.
- Transfer the front enable and isolated field references exactly as shown in the wiring record.
- Confirm the S5 address allocation before returning program control to the outputs.
