Product Description

SIEMENS 6ES7 134-4JB51-0AB0

The SIEMENS 6ES7 134-4JB51-0AB0 is an analog input module belonging to the SIMATIC ET 200S distributed I/O system. This electronic module is specifically designed for acquiring temperature signals from thermocouples (TC) and resistance-based sensors. It features two analog inputs with high resolution (16 bits including sign) suitable for precise temperature measurements in various industrial automation processes. It supports multiple thermocouple types and resistance ranges, offering flexibility for different sensor applications within a compact 15mm width.
