Omron DRT1-TS04P Analog Input Terminal PLC Module

The Omron DRT1-TS04P Temperature Input Terminal is a 4-channel analog input module for Omron DeviceNet/DRT1 series remote I/O systems, designed to acquire temperature data from RTD sensors and transmit it to a PLC for process control. Each of the four inputs is a platinum resistance thermometer (RTD) type, powered by a 24 V DC supply, with a conversion cycle of approximately 250 ms for all channels. It supports a operating temperature range of -20°C to +60°C, and is mounted via DIN rail or screw mounting with an M3 screw terminal block; its protection rating is IP20 and it weighs about 0.17 kg. Key features include scaling, a comparator, and data processing capabilities to support distributed temperature monitoring across networks. Common applications encompass distributed temperature monitoring and process control in manufacturing lines, HVAC systems, and other industrial environments where reliable, localized temperature data is required with reduced wiring. The module belongs to the DRT1 (DeviceNet Remote I/O) series and is currently listed as discontinued/obsolete. For replacement, Omron offers options such as the DRT2-TS04P, CRT1-TS04P, and NX-TS2101 to maintain similar functionality in migrated or legacy control schemes.
