Manufacturer: SIEMENS Model: 6ES7231-4HF32-0XB0 Product Type: Analog Input Module Number of Input Channels: 8 Voltage Range: ± 10V, ± 5V, ± 2.5V Current Range: 0-20ma/4-20ma Resolution: 12-bit + sign (13-bit ADC) Weight: 0.207 KG Dimensions: Not available SIEMENS The 6ES7231-4HF32-0 XB0 analog input module is an integral part of the SIMATIC S7-1200 series. Designed for industrial automation applications.The module provides high accuracy and reliability, and can handle many types of analog signal inputs, such as voltage and current signals. Its eight input channels can be flexibly configured to meet the needs of different application scenarios. In addition, the module uses advanced signal processing technology to ensure the stability and accuracy of data acquisition. It is suitable for occasions requiring precise measurement and control, such as temperature monitoring, pressure detection, etc.

The BT51T 24DC safety relay is a compact universal/expansion safety relay designed to monitor safety devices (e.g. emergency‑stop buttons, safety switches/interlocks, safety mats/edges, light‑curtains, gates/doors) and provide multiple safety‑rated outputs. It accepts either single‑ or dual‑channel safety inputs, supports supervised reset/test input (ensuring downstream contactors or valves have dropped before restart), and can function as a stand‑alone safety relay or as an output‑expansion relay. Its compact width (22.5 mm) and DIN‑rail mounting make it suitable for installation in control cabinets, and front‑panel LEDs provide status indication (supply, relay, and output status). Delay for output drop (soft‑stop) is configurable between 0 and 1.5 s, enabling controlled shutdowns when required.

The EOCRDS1-30NBQ is a compact and reliable electronic motor protection relay from the EOCR-DS1 series, part of Schneider Electric's motor protection portfolio (originally developed by nVent/Samwha EOCR). This microprocessor-based relay is specifically designed to provide essential protection for three-phase AC motors against common electrical faults in an ultra-compact, space-saving package.
