16 Channel Multi-Parameter Datalogger | Temperature RTD Pressure 4-20mA 0-5V Voltage with RS485

The SPSGT71R is a high-integration, color touchscreen data logger designed for advanced process monitoring and industrial automation. This item ships direct from the manufacturer. Please allow 10-15 business days for order processing and shipment. Built for flexibility and reliability, it supports multi-channel input, control output, and seamless communication across a wide range of applications. Engineered for demanding environments, the SPSGT71R accommodates 1 to 16 channels of analog input, along with 1 to 6 relay outputs for precise control and response. It also provides 1 to 6 channels of 24V DC sensor power supply, simplifying system integration and reducing the need for external power sources. Dual communication interfaces, RS232C and RS485, enable easy connectivity to external devices and control systems. The RS232C interface supports direct connection to a micro printer for on-site data output and reporting. Built-in power-off protection and clock protection ensure data integrity and continuous operation, even in the event of power interruptions. Applications Ideal for use in petrochemical processing, food production, environmental monitoring, and medical applications, the SPSGT71R enhances operational visibility and supports smarter, intelligent manufacturing and energy management.
