          PRODUCT DESCRIPTION

          6ES5456-4UA12 AC digital output module

          Siemens 6ES5456-4UA12 is a sixteen-channel AC digital output module for SIMATIC S5-135U and S5-155U controllers. Its outputs switch 115 to 230 V AC loads and are divided into two electrically isolated groups of eight, with fuses protecting groups of four outputs.

          The permissible load-supply range is 88 to 264 V AC at 47 to 63 Hz. Available output current depends on ventilation: up to 2 A per channel with ventilation, or 1 A without it, subject to the separate group limits. A front-connector enable circuit and the load-specific current limits form part of the installed output arrangement.

          SYSTEM & REPLACEMENT CHECK

          Information needed before ordering

          Three direct checks to secure your system integration and minimize ordering risks.

          Information

          System integration Replacement check Manuals & support
          SYSTEM INTEGRATION

          Integrate 6ES5456-4UA12 within SIMATIC S5-135U/155U

          Assign the sixteen output addresses in the S5 rack configuration and wire the two isolated load groups according to the 456-4UA12 diagram. The module is an AC output assembly and must not receive a DC-load circuit in place of the specified supply.
          Design the ventilation and current budget together. With ventilation each four-output group permits 6 A total, while without ventilation the limit is 4 A; lamp groups remain subject to their lower 2.5 A aggregate limit.
          Fit the specified 6.3 A fast fuses and preserve the front-connector enable arrangement. The typical 39 W dissipation is significant for enclosure thermal planning, and the 300 m unshielded line limit does not remove the need for suitable cable routing.

          Features:

          • Digital outputs: 16
          • Rated load supply: 115 to 230 V AC
          • SIMATIC S5-135U/155U
          Use 6ES5456-4UA12 only within the documented SIMATIC S5-135U/155U arrangement and applicable installation instructions.
          INTERCHANGEABILITY

          Replace 6ES5456-4UA12 within SIMATIC S5-135U/155U

          Isolate every AC supply feeding the module before removing the front connector. Record the output addresses, group supply wiring and enable jumper, and identify the fitted fuses and cabinet ventilation arrangement.
          Match the 456-4UA12 model and its sixteen AC outputs. Related S5 modules can differ in load voltage, channel current and connector arrangement; the original 2 A rating is valid only under its specified ventilation conditions.
          After replacement, verify fuse continuity and the enable circuit before restoring the load supplies. Test the affected outputs against the connected loads, checking leakage-sensitive devices and aggregate current under the actual enclosure conditions.

          Features:

          • Intergroup insulation test: 2000 V AC
          • Mating terminals and installed configuration
          • Post-exchange functional validation
          Use 6ES5456-4UA12 only within the documented SIMATIC S5-135U/155U arrangement and applicable installation instructions.

          FREQUENTLY ASKED QUESTIONS

          Questions buyers ask about 6ES5456-4UA12

          Direct answers about identity, compatibility, stock, warranty, payment and shipping.

          • Does 6ES5456-4UA12 always deliver 2 A per channel?

            No. 6ES5456-4UA12 permits 2 A with ventilation and 1 A without ventilation, with additional limits for each group of four outputs.

          • Which AC supply span is permitted for 6ES5456-4UA12?

            6ES5456-4UA12 accepts 88 to 264 V AC at 47 to 63 Hz, covering its nominal 115 to 230 V AC load supply.

          • How are 6ES5456-4UA12 outputs fused?

            6ES5456-4UA12 uses a 6.3 A fast fuse for each group of four outputs; fuse protection is conditional short-circuit protection.

          • What current limit applies to an unventilated 6ES5456-4UA12 group?

            Four outputs on 6ES5456-4UA12 are limited to 4 A total without ventilation, rather than four times the individual channel rating.

          • Why might an 6ES5456-4UA12 output show current while off?

            6ES5456-4UA12 allows up to 5 mA off-state residual current. Check whether the receiving load is sensitive to that leakage.

          • What heat load does 6ES5456-4UA12 add to the enclosure?

            The 6ES5456-4UA12 manual lists 39 W dissipation at rated operation, making ventilation part of the electrical selection.

          • What must an 6ES5456-4UA12 purchase enquiry state about cooling?

            State 6ES5456-4UA12, the installed rack and whether forced ventilation is present. The usable output loading depends on that arrangement.

          • Which parts should an 6ES5456-4UA12 quotation distinguish?

            Quote the 6ES5456-4UA12 electronics, front connector and fuses explicitly; connector and protection hardware should not be assumed from the module number.
