The following are located on the TM31 Terminal Module:

• 8 digital inputs
• 4 bidirectional digital inputs/outputs
• 2 relay outputs with changeover contact
• 2 analog inputs
• 2 analog outputs
• 1 temperature sensor input (KTY84-130 or PTC)
• 2 DRIVE-CLiQ sockets
• 1 connection for the electronics power supply via the 24 V DC supply connector
• 1 PE/protective conductor connection

The TM31 Terminal Module can be snapped onto a TH 35 top-hat rail to EN 60715 (IEC 60715).

The signal cable shield can be connected to the TM31 Terminal Module via a shield connection terminal, e.g. Phoenix Contact type SK8 or Weidmuller type KLBU CO 1. The shield connection terminal must not be used for strain relief.

The status of the TM31 Terminal Module is indicated via a multicolor LED.
