Features:

  • Eight isolated inputs accept 115 to 230 V AC field states.
  • The input circuit handles pulse trains up to 20 Hz.
  • The 436-4 compact U format suits legacy S5 input racks.
The input stage handles pulse trains up to 20 Hz.

The UB12 order is an eight-point AC input card in a 40 mm x 255 mm x 195 mm, 0.5 kg format.

De-energize the field wiring, identify the front connector, and preserve the eight-point address order during installation.

Availability follows the UB12 input-module record and a review of the required AC field interface.

  • Monitors eight AC switch and contact states in machine panels.
  • Collects permissive feedback for S5 sequence and interlock logic.
  • Replaces an installed 436-4 input card while preserving slot and channel order.
  • The AC input card is specified for the SIMATIC S5 operating climate and cabinet conditions.
  • Its insulation arrangement is tested for the documented group and group-to-earth voltage levels.
  • Keep unused rack openings closed so the assembled station maintains the stated IP20 protection.
  • The eight input channels are isolated from one another for the 115 V AC and 230 V AC field circuits.
  • The 2-wire BERO option must be wired within the permitted input-current behavior of the AC interface.
  • Observe the front-connector isolation test boundary when checking field wiring with power removed.
  • Select the rack address and input delay in line with the existing S5 input image.
  • The pulse-input setting is suitable for the documented low-frequency AC status signals.
  • A front connector jumper defines the enable condition used by the installed control cabinet.
Description
Siemens 6ES5436-4UB12 is an eight-channel 436-4 digital input module for floating 115–230 V AC signals. It transfers discrete field states into the S5 controller through isolated input circuits.

The input points can collect switch, limit, permissive, and contact feedback in machinery panels using the 436-4 address position. Its compact U construction preserves the established front-wiring approach. The input stage is intended for a 20 Hz AC signal rate with the documented delay characteristics of the 436-4 family.

Service work should isolate the AC source, confirm the eight-channel connector order, and retain the original input grouping. The module measures approximately 40 mm × 255 mm × 195 mm and 0.50 kg. Use the module only with the specified high-voltage AC sensing circuits and preserve the original separation between field groups.

Technical notes
Install Siemens 6ES5436-4UB12 only after confirming that the eight AC input circuits are de-energized and that the common wiring matches the 436-4 position.
