TM-SG4: Terminal module for RS-485 network with termination resistors and Pull-high/Pull-low resistors.

The active terminator, thanks to the adjustable resistors via DIP switch, allows for precise calibration of RS485 line resistors, for example on MODBUS networks.

It optimizes the signal on RS-485 networks by reducing noise.

## Technical Features

 

- Pull-high/Pull-low resistance selectable via DIP switch
- Termination resistance with 15 selectable steps
- LED for power/termination indication
- DIN-Rail mounting
- Extended temperature range: -25 °C ~ +75 °C
