Product Description:
The 0GH-AT600 from B & R Automation belongs to the 0GH PLC Modules series and functions as an analog input card for thermocouple-based temperature acquisition inside distributed control cabinets. It converts low-level millivolt signals into digital values that the CPU can process. This supports closed-loop heating, cooling, and safety interlocks in industrial automation.
The module’s baseline accuracy is ±25 µV (±0.036%), which limits total error when reading low-level thermocouple signals. A conversion is completed every 20 ms, so the controller receives fifty updates per second for timely reaction to thermal transients. The unit has 16 differential input channels, allowing multiple zones to be monitored on one board. Temperature stability is supported by a gain drift of ±0.006 %/°C, so amplification changes only slightly as the board warms. An offset drift of ±1.1 µV/°C (±0.0016 %/°C) keeps zero shift minimal, and repeat precision of ±0.008 % helps successive samples remain closely matched when the process stays steady. The sensing front end tolerates process temperatures from -50 to +750 °C, covering applications from cryogenic storage to high-temperature ovens.
The maximum internal scan loop finishes in 235 ms, which sets the upper bound for applications that do not require faster aggregate cycle times. Resolution is matched to a step size of 0.1 °C, enabling fine setpoint tracking without excessive data traffic. The compensation range of -20 to +90 °C lets the cold-junction circuit maintain accuracy even when the cabinet temperature drifts. Linearization is handled automatically, so external lookup tables are not required. Each channel expects a Type L thermocouple made of FeCuNi alloy and referenced to DIN 43710, which keeps wiring consistent across European machinery.
