Features:
- 16 digital input channels operating at 48/60 V UC rated voltage with optical galvanic isolation in 4 distinct groups.
- Wide logic state signal evaluation range from 0 to 10 V for signal "0" and 30 to 72 V for signal "1".
- Fast response performance with input delay times of 2 to 13 ms (0 to 1) and 10 to 25 ms (1 to 0).
The Siemens 6ES5432-7LA11 is a factory-configured digital input module designed specifically for installation in SIMATIC S5-115U and S5-115H rack assemblies.
This module processes external binary process signals from field sensors and switches, converting them into internal logic voltage levels through optocouplers for reliable signal transmission across long distances.
During system integration, field wiring must be routed through a dedicated 24-pin front connector, maintaining efficient low-power backplane operation within the system rack.
The Siemens 6ES5432-7LA11 is available in new surplus and fully tested refurbished condition, backed by standard warranty coverage not provided by the original manufacturer (OEM).
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Digital signal acquisition from field switches, pushbuttons, and sensors in SIMATIC S5-115U automation racks.
- Industrial process monitoring requiring high electrical noise immunity over long field cable distances.
- Fault-tolerant PLC control systems using SIMATIC S5-115H redundant configurations.
- Requires no complex module firmware setup or software parameterization for hardware deployment.
- Input address mapping is assigned directly within the central controller user program.
- Operates via standard hardware jumper configurations on the underlying rack backplane.
- Meets VDE 0160 standards for electrical clearance and insulation voltage ratings in control systems.
- Tested at 500 V AC to verify robust galvanic separation between field circuits and system ground.
- Complies with industrial safety regulations for low-voltage signal conditioning and isolation.
- Pure hardware-based input module requiring no firmware updates or microcode maintenance over its operating lifecycle.
- Input addresses and operational behavior are defined entirely within the SIMATIC S5 central processing unit program.
- Ensures long-term interchangeability across existing S5-115U subracks without system software modifications.
