Overview
- 16-channel digital input module
- Approved in accordance with the railway standards EN 50155, EN 15121, EN 50124, EN 50125 and EN 45545 for use in rail traffic
- For flexible adaptation of the controller to the corresponding task
- For subsequent expansion of the system with additional inputs
Application
The digital module inputs records 24 V DC signals in the system and forwards them to the controller. Switches and 2-wire proximity switches can be connected.
Input modules have settable parameters and diagnostic functions and can thus be adapted flexibly to the respective process requirements.
Design
- Installation on the S7-1500 mounting rail using one single screw
- Standardized 40-pin front connector using screw terminal or push-in technology
- Standardized, harmonized front connector assignment for easier wiring
- Connectable core cross-sections: 0.25 mm2 to 1.5 mm2 (AWG24 to 16)
- Integrated potential bridges for flexible creation of potential groups
- Front connector can be set to prewiring position
- Front flap with expandable cable compartment, even if fully wired
- Unambiguous labeling on front of module:
- Module type
- Article No.
- Hardware and firmware version
- Channel numbers labeling
- Cabling diagram
Included in the scope of delivery:
- One labeling strip for manual labeling
- One U connector
- Printed front door
Function
- Uniform display and diagnostics concept:
- Module status display for ERROR (red LED) and RUN (green LED)
- Channel status display for signal state log. “0” and log. “1” (green LED) or indication of wire break (red LED)
- Display for monitoring the 24 V DC supply voltage (green LED)
- Supported functions:
- Identification and maintenance data IM0 to IM3
- Firmware update
- Module-granular shared device and MSI (modular shared input);
in combination with PROFINET these allow assignment to several IO controllers - Channel-specific parameter assignment (only HF modules)
- Hardware interrupts (only HF modules)
- Channel-granular diagnostics (only HF modules)
- Isochronous mode (dependent on the module)
