TriBox mini controller

2 channels digital transmitter

Control unit for digital sensors


2 channels digital transmitter, with 2 inputs for digital sensors and 2 analog outputs 4 ... 20 mA. The TriBox mini is compatible with all TriOS digital sensors, measurement data and sensor parameter information can be accessed via a web browser-accessible interface with Wi-Fi or Ethernet connection.

This module allows the triggering of a relay output when exceeding the programmed threshold and also makes it possible to control a compressed air injection for the automatic cleaning of the optical sensors.

Measurement principle

The TriBox mini is equipped with two sensor inputs with MC12 connectors. The analog outputs, relays and compressor control are connected via the two cable glands (on the left). The power cable is already mounted at the bottom right.
