CHESTER
Input

A configurable NB-IoT/LTE-M/LoRaWAN device that samples, aggregates, buffers, and reports values on four digital/analog inputs and captures changes on digital inputs.

CHESTER Input catalog application allows the measurement values on up to for input channels.

0-28 V input
voltage transmitter

Connect sensor, controller, or PLC and configure sampling and aggregation of data.

4-20 mA current
loop transmitter

Connect sensor, controller, or PLC and configure sampling and aggregation of data.

Digital input
trigger and counter

Use two digital NPN/PNP inputs. One for the trigger (switch, button, relay) and one for the counter (S0 pulse output).

Reliable operation
+ wireless connectivity

The device runs from the mains with a backup battery and transfers data over cellular networks (NB-IoT / LTE-M) or public/private LoRaWAN networks.

Application areas

Typical use cases

With CHESTER Input, you can efficiently monitor power generation and implement it into diesel generators to send machine state reports.

The multi-functionality of our device is ideal solution for a precise monitoring of failures and breaches of electric fences.

Moreover, the versatility of CHESTER Input allows for the weight measurement of bee hives and volume monitoring of grain silos.
