TIU-32C

The TIU-32 is a 32-channel thermocouple interface unit. Two versions are available, the TIU-32 and the TIU-32C providing output as either 0-5V analogue or via CAN.

Cold junction is provided with the TIU-32 and TIU-32C. In the case of the standard TIU-32 the 32 compensated signals are then multiplexed (32:2) to provide two 0-5V scaled outputs. Channel selection is under the control of a host ECU via 4 channel select pins.

The TIU-32C CAN-linked version is fitted with a microcontroller that samples the analogue signals and scales them accordingly ready for transmission to a control unit via the CAN bus at speeds up to 1Mbps.
