• 4, 8 and 16-channel digital input (DI) modules
• Approved in accordance with the EN 50155, EN 15121, EN 50124, EN 50125 and EN 45545 railway standards for use in rail traffic

For different requirements, the digital input modules offer:

• Function classes Standard and High Feature
• BaseUnits for single or multiple-conductor connection with automatic slot coding
• Individual system-integrated load group formation with self-assembling voltage distribution bars (a separate power module is no longer required for ET 200SP)
• Connection option of sensors compliant with IEC 61131 Type 1, 2 or 3 (module-dependent) for rated voltages of up to 24 V DC or 230 V AC
• Clear labeling on front of module
• LEDs for diagnostics, status, supply voltage and faults
• Electronically readable and non-volatile writable rating plate (I&M data 0 to 3)
• Optional accessories
  • Labeling strips (film or card)
  • Reference identification label
  • Color-coded label with module-specific CC Code
  • Shielding terminal

A quick and clear comparison of the functions of the different DI modules is offered by the TIA Selection Tool.
