750-458 Eight-channel analogue input terminal thermocouple (TC), freely

The input terminal enables the direct connection of thermocouples.

Linearization across the entire temperature range is handled by the bus terminal.

To compensate for the error voltage at the terminal point in the range 0°C - 55°C, cold junction compensation is carried out using comparative measurement.

A red error LED indicated when a break in the line has occurred.

Unused channels can be deactivated.

The bus terminal is freely configurable via WAGO-I/O-CHECK and GSD files.

The versatile setting options and the high level of accuracy are impressive.

Sensor types: Type K, J, B, E, N, R, S, T, U, C; voltage measurement -30 mV to +30 mV, -60 mV to +60 mV, -120 mV to +120 mV, -240 mV to +240 mV.

Measurement error 25°C: without cold junction compensation: = ± 1 K (type E, N, K, T, J, C); = ± 2 K (type S, R); = ± 3 K (type B); measurement error for cold junction compensation: = ± 4 K.
