Omron DRT2-TS04T 24VDC DeviceNet Slave Analog I/O Remote Temperature Input Terminal

Omron DRT2-TS04T 24VDC DeviceNet Slave Analog I/O Remote Temperature Input Terminal

1. Overview of the Omron DRT2-TS04T

The Omron DRT2-TS04T is a DeviceNet remote I/O terminal designed for multi-point temperature acquisition in industrial sites. Measuring only 50 mm in width, it stably connects four thermocouple signals in environments ranging from -10°C to +55°C, directly transmitting field temperature data to the PLC via the DeviceNet network at high speed. This eliminates the need for analog modules and long compensation cables, streamlining temperature control system wiring by over 60%.

The product features a built-in 16-bit, high-resolution A/D converter and supports all thermocouple types: K, J, T, E, N, R, S, and B. It has a sampling period of 250 ms and a measurement accuracy of ±0.3% F.S. Each channel features independent cold junction compensation, along with triple diagnostics for disconnection, short circuit, and over-range. Faulty channels automatically generate alarms, allowing maintenance personnel to locate anomalies in seconds using the dual-color LED on the front panel or network messages. Standard DIN rail mounting and pluggable terminal blocks ensure module replacement without rewiring.
Typical applications include multi-temperature zone monitoring for extruders, group control of heat treatment furnaces, food sterilization tunnels, and lithium battery coating ovens, all requiring distributed, high-precision temperature management. With Omron FINS command compatibility, DeviceNet plug-and-play support, and CE/UL certification, the DRT2-TS04T transforms traditional temperature control cabinets into networked, digital, and predictively maintainable intelligent temperature control nodes.

3. Intelligent Functions and Typical Applications
Channel-Specific Configuration: Thermocouple type, range, linearization, cold junction compensation, and alarm limits can be configured for each channel using DIP switches or the host configurator.
Cold Junction Compensation: A built-in high-precision sensor automatically compensates for terminal temperature; external Pt100 cold junction expansion is supported. Alarms and Diagnostics: Configurable upper and lower limits, disconnection, short circuit, and over-range alarms; alarm status is written to the DeviceNet status word in real time.
Scaling and Filtering: Supports linear scaling, digital filtering, and average/peak hold, meeting the transient temperature recording needs of extruders, heat treatment furnaces, and other applications.
Typical Scenarios:
– Four-zone closed-loop control of plastic extruders
– Distributed temperature monitoring of reflow ovens
– Group control system for lithium battery coating ovens
– Temperature traceability in food sterilization tunnels
