The WIN-IO-2PT2THM is a DIN-rail mountable industrial temperature measurement module that converts two RTD (PT100/PT1000) and two thermocouple (K, J, N, R, S, T, E, B) inputs into a Modbus RTU signal over an isolated RS485 interface for integration into PLCs, SCADA, and industrial automation systems.

Features

  • Multi-channel input for two RTDs (PT100/PT1000) and two thermocouples (K, J, N, R, S, T, E, B) with high-accuracy 15-bit/19-bit ADC resolution.
  • Modbus RTU protocol over RS485 enables robust, long-distance communication up to 700 meters for remote monitoring and control.
  • Optical isolation and resettable fuse protection ensure signal integrity and safeguard against reverse polarity and electrical transients.
  • Simple DIP-switch configuration for baud rate (9600-115200 bps) and slave ID (1-15) eliminates complex software setup.
  • Compact, DIN-rail mountable industrial housing with LED status indicators, powered by 24V AC/DC for low-power, reliable operation.

Description

The WIN-IO-2PT2THM is a dedicated industrial interface module designed for precise temperature acquisition in automation and process control environments. It bridges the gap between analog temperature sensors and digital control networks by providing isolated signal conditioning for RTDs and thermocouples, outputting standardized Modbus RTU data frames over a robust RS485 bus.

Engineered for harsh industrial settings, the module incorporates optical isolation and protective fuses to defend against ground loops, ESD, and electrical fast transients (EFT). Its low-power design and DIN-rail form factor make it ideal for panel integration, while the configurable communication parameters allow seamless connection to PLCs, HMIs, and data acquisition systems without firmware modifications.

Key Features

  • Dual-channel RTD input supporting PT100 and PT1000 sensors in 2-wire or 3-wire configurations.
  • Dual-channel thermocouple input compatible with types K, J, N, R, S, T, E, and B.
  • Industrial-grade Modbus RTU slave device with RS485 interface for network integration.
  • High-precision analog-to-digital conversion (15-bit for RTD, 19-bit for thermocouple) for accurate temperature monitoring.
  • Optically isolated inputs and outputs for enhanced noise immunity and system protection.
  • Hardware-configurable via DIP switches for baud rate and Modbus slave address.
  • Compact, DIN-rail mountable enclosure with LED indicators for power and communication status.
  • Wide-range 24V AC/DC power supply with low operating current for energy-efficient deployment.

Applications

  • Industrial process control and monitoring for HVAC, manufacturing, and chemical processing.
  • Remote temperature data acquisition in SCADA systems and building automation.
  • Integration into PLC-based automation for precise thermal management.
  • Environmental monitoring and scientific data logging applications.
  • Energy management systems monitoring boiler, oven, or reactor temperatures.

Frequently Asked Questions

How do I configure the Modbus baud rate and slave address on the WIN-IO-2PT2THM?

The module is configured via physical DIP switches located on the unit. Set the switches according to the manual to select a baud rate between 9600 and 115200 bps and assign a unique Modbus slave ID from 1 to 15. No software or programming is required for this basic communication setup, making it quick to integrate into existing RS485 networks.

What types of thermocouples and RTD wiring does this module support?

It supports two RTD inputs for PT100 or PT1000 sensors, configurable for either 2-wire or 3-wire connections. The two thermocouple channels are compatible with types K, J, N, R, S, T, E, and B. Ensure you connect the sensor polarity correctly and refer to the datasheet for specific wiring diagrams and any required jumper settings for optimal accuracy.

What is the benefit of the optical isolation in this temperature module?

Optical isolation electrically separates the sensitive sensor inputs and the RS485 communication bus. This protects your main control system (PLC/PC) from voltage spikes, ground loop currents, and electrical noise commonly found in industrial environments, ensuring reliable data transmission and preventing damage to connected equipment.

How do I power the WIN-IO-2PT2THM and what are its electrical requirements?

The module operates on a wide-range 24V AC or DC power supply, with a maximum current draw of 80mA. Connect the power terminals observing correct polarity, as the module includes reverse polarity protection via a resettable fuse. The low power consumption makes it suitable for use in centralized control panels with standard industrial power sources.
