Siemens 7ND9400-8AJ

The Siemens 7ND9400-8AJ is a six-channel measurement module designed for precise DC voltage, current, and thermocouple input. This module supports input ranges from -10 mV up to 1 V for voltage and from -4 mA to 20 mA for current signals. It is suitable for temperature measurement using thermocouples when paired with devices like the Variograph models 7ND3521, 7ND3560, and 7ND3590, provided the firmware is updated to the required version. You can install up to two of these modules per device, though they should not be mixed with three-channel modules. Distributed by BSP Automation, this module offers reliable performance for multi-channel data acquisition applications.
