SPT-86L Temperature and Voltage Transmitter

Explore the SPT-86L Module, an advanced temperature and voltage-to-current transmitter. Designed for versatility, it supports the 4-20 mA standard and features RS-485 data reading capabilities. It offers a broad input range, including Pt 100/500/1000, multiple thermocouples (K/S/J/T/N/R/B/E), and 0-60 / 0-75 / 0-100 / 0-150 mV options – though only one input is usable at a time. The module ensures precise measurements with full linearisation and automatic cold junction compensation in thermocouple mode. Its configurable milivoltage input and direct current output control adapt to diverse applications. Easily set up via RS-485 and S-Config software, the SPT-86L is also available with optional factory pre-configuration for added convenience.

  • Electrical Connections: 10-30V DC, max. 0.65 W consumption
  • Media Compatibility: Wide temperature range for various sensor types
  • Special Features: RS-485 Modbus RTU, EEPROM memory, DIN rail mounting

SPT-86L Product Highlights

The SPT86L Temperature and Voltage Transmitter is a versatile module that serves as an insulated temperature and voltage to current transmitter, complying with the 4-20 mA standard. It offers the convenience of data reading through the RS-485 interface. This transmitter module features a single input that supports a wide range of measurements, including Pt 100/500/1000, thermocouples K/S/J/T/N/R/B/E, and 0-60 / 0-75 / 0-100 / 0-150 mV. However, only one type of input can be used at a time. The measurement inputs are equipped with full linearisation of characteristics and automatic compensation of the cold junction temperature in the thermocouple mode. The Pt mode supports various connection methods such as 2-, 3-, and 4-wire configurations, while the millivoltage input offers selectable characteristics like linear, square, square root, or user-defined. By default, the measurement output is delivered to the current output, but the current output can also be controlled directly through the serial interface. Configuration and data reading can be performed via the RS-485 (Modbus RTU) interface using the S-Config software on a PC. Additionally, each unit can be preconfigured at the factory upon request.
