The T3480 is a six-channel 4–20 mA guarded analog output module for the ICS Regent system. Dual conversion paths, triplicated I/O Safetybus communication and continuous circuit comparison help prevent a single internal or system fault from changing an output unintentionally.
- Six 4–20 mA output channels
- Dual 12-bit D/A converters per channel
- 0–4095 application data range
- Single-module fail-safe operation
- Two-module fault-tolerant operation with hot replacement
- 2500 V minimum field-to-logic isolation

Regent processors send triplicated commands over the I/O Safetybus. Two independent logic sections vote the data and drive separate D/A paths for every channel. One path drives the field output and the other provides a reference; both signals must agree before the output is enabled.
For fault-tolerant service, two T3480 modules are wired in parallel with STATUS IN and STATUS OUT cross-strapped. One controls the loads while the standby module tests its drive circuits. Transfer to the standby module occurs in less than 5 ms after a controlling-module failure.
- System: ICS Regent I/O chassis with triplicated I/O Safetybus.
- Software: WINTERPRET I/O Configuration Editor.
- Programming: 0–4095 corresponds to 4–20 mA. Engineering units can be converted with the analog scaling function block.
- Slot keying: upper connector position 9 and lower connector position 10.
- Fault response: the chassis fault-mode jumper selects shutdown-to-zero or hold-last-state behavior.
- Confirm the catalog number, hardware revision and Regent compatibility.
- Verify the external 24 VDC supply and available current.
- Connect every output to a load. Short the two terminals of each unused channel at the I/O chassis as specified in the manual.
- For a redundant pair, verify parallel output wiring and A/B status cross-strapping.
- Confirm slot keying, fault-mode jumper position and WINTERPRET point definitions.
The T3480 is TÜV certified as non-interfering and is intended for non-safety-critical outputs within a safety system. Process safety must not depend on this module. Annual recalibration is recommended. Calibration and latent-fault testing require an operational Regent system, WINTERPRET, precision loads and the T3322 I/O module extender.
- Second T3480: required for the documented fault-tolerant configuration.
- T3322 I/O module extender: used for calibration and latent-fault testing.
- Regent I/O chassis and WINTERPRET: required system and engineering environment.
