TM31 Terminal Module Siemens

Обзор



The TM31 Terminal Module can be used to increase the number of available digital inputs and outputs and the number of analog inputs and outputs within a drive system.

The TM31 Terminal Module also features relay outputs with changeover contact and a temperature sensor input.

Дизайн



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 Weidmüller type KLBÜ 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.

Интеграция



The TM31 Terminal Module communicates with the CU310 or CU320-2 Control Unit via DRIVE-CLiQ.

1) The specified delay times refer to the hardware. The actual reaction time depends on the time slot in which the digital input or output is processed.

2) f the analog input is to be operated in the signal processing sense with continuously variable input voltage, the sampling frequency fa = 1/ttime slice must be at least twice the value of the highest signal frequency fmax.
