µCAN.4.ti-BOX — 4-Channel Temperature Input Module

The µCAN.4.ti-BOX provides four inputs for measuring temperature sensors.
Signals from resistance sensors as well as thermocouples can be acquired at a total sampling rate of 400 Hz.
Sensor signals are evaluated and linearized within a rugged die-cast aluminium housing.
The CAN interface supports CANopen and SAE J1939 protocols.

Features

The µCAN.4.ti-BOX digitizes measurement values of temperature sensors and provides these values in °C
with a resolution of 0.1 °C. Module address and bitrate can be set via DIP switch or CAN bus (LSS, CiA 305);
automatic bitrate detection is also supported.

Connectivity

Up to four measurement sensors can be connected to the module.
The sensor type is selected via CAN bus. When a thermocouple type is chosen,
cold-junction compensation activates automatically.

Platinum temperature sensors: Pt100, Pt500, Pt1000
Thermocouples: types J, K, L, T

Communications

The digitised temperature values of the µCAN.4.ti-BOX are transmitted via CAN bus.
The CAN bus bitrate is adjustable from 50 kbit/s to 1 Mbit/s.
A terminating resistor can be activated via a hardware switch.
The CANopen protocol complies with CiA 301, CiA 305 and CiA 404.
Both 11-bit (CAN 2.0A) and 29-bit (CAN 2.0B) identifiers may be used for process data.
