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
