S800 I/O – TU850

The TU850 MTU can have up to 16 I/O channels. The maximum rated voltage is 50 V and maximum rated current is 15mA per I/O channel (digital input) or 25mA per two I/O channels (analog input).

The MTU distributes the ModuleBus to the I/O module and to the next MTU. It also generates the correct address to the I/O module by shifting the outgoing position signals to the next MTU.

The MTU can be mounted on a standard DIN rail. It has a mechanical latch that locks the MTU to the DIN rail. Two mechanical keys are used to configure the MTU for different types of I/O modules. This is only a mechanical configuration and it does not affect the functionality of the MTU or the I/O module. Each key has six positions, which gives a total number of 36 different configurations.

Features and Benefits

  • Complete 2-wire connections for up to 16 channels.
  • Each channel has one current limited sensor/transmitter power outlet terminal and one signal terminal.
  • Current limitation in sensor/transmitter supply is implemented with disconnectable PTC fuse.
  • Process voltage can be connected to 2 individually isolated groups, if the I/O module supports it.
  • Connections to ModuleBus and I/O modules.
  • Mechanical keying prevents insertion of the wrong I/O module.
  • Latching device to DIN rail for grounding.
  • DIN rail mounting.
