Features:
- Acquires four mutually isolated three-wire RTD input channels.
- Supports independently configured Pt100 and JPt100 sensors.
- Processes resistance through excitation, isolation, V/F conversion and CPU scanning.
SRT012 acquires resistance-temperature signals for the TOSDIC-CIE DS intelligent I/O arrangement and converts four field RTD channels into digital process values.
A controlled excitation current is applied to each three-wire RTD. Resistance detection and the analog V/F conversion path determine the sensor value, while the three-wire connection compensates for lead resistance.
Confirm the UIOU59 base card, channel sensor type, three-wire terminal assignment, configured filter and engineering scaling. Do not substitute the similarly named STC012 thermocouple module.
Availability is reviewed against the exact SRT012 order identity and requested supply condition; manufacturer lifecycle status: Active / Available from OEM.

- An analog multiplexer and internal CPU sequence the four isolated channels. The selected 50 or 60 Hz filter determines the documented update cycle, and channel data is exchanged over redundant RS-485 buses.
- The module is used for plant temperature measurement where Pt100 or JPt100 sensors are connected to legacy Toshiba DPCS/TOSDIC installations, including process vessels, rotating equipment and utility systems.
- Communicates with the intelligent I/O system through redundant RS-485 buses.
- Converts four three-wire RTD signals into digital temperature values.
- Supports independently configured Pt100 and JPt100 sensors on each point.
- Uses selectable 50 Hz or 60 Hz filtering for stable measurement.
- Provides four isolated resistance-temperature input channels.
- Updates channel data every 186 ms at the 50 Hz filter setting.
- Reduces update time to 159 ms when the 60 Hz filter is selected.
- Requires the UIOU59 base card with two modules per documented arrangement.
- Three-wire terminal assignments must follow the configured sensor type and scaling.
- The similarly named STC012 thermocouple module is not an interchangeable substitute.
