Description
The T8480C Trusted TMR Analog Output Module is a safety-critical industrial control component designed for high-reliability automation systems. It is widely used in demanding process environments where stable and fault-tolerant analog output control is required.
Applications
Thermal Power Plants: Controls turbine electro-hydraulic servo systems to maintain stable speed and load.
Natural Gas Transmission: Drives pressure and anti-surge control valves for safe long-distance transport.
Refineries: Manages critical control valves in complex refining processes with high safety integrity.
Ethylene Plants: Controls compressor speed actuators to prevent abnormal shutdowns.
Desalination Plants: Regulates high-pressure pumps in corrosive continuous operation environments.
Features
40 Triple Modular Redundant (TMR) output points per Module.
Comprehensive, automatic diagnostics and self-test.
Automatic line monitoring per point to detect open circuit and short circuit field wiring and load faults.
2500 V impulse withstand opto/galvanic isolation barrier.
Automatic over-current protection (per channel), no external fuses required.
On-board Sequence of Events (SOE) reporting with 1 ms resolution.
Module can be hot-replaced on-line using dedicated Companion (adjacent) Slot or SmartSlot (one spare slot for many Modules) configurations.
FAQ
Q: What is the full-scale accuracy of the T8480C analog output module at +25°C?
A: At +25°C, calibration accuracy is ±0.1% full scale, and ±0.25% across 0°C to +60°C.
Q: What supply voltages are required for the T8480C module?
A: IMB supply is 20V DC to 32V DC, and field supply is 18V DC to 32V DC.
Q: What is the recommended output range and channel count of the T8480C module?
A: It has 40 channels in 5 groups, with a recommended 1 mA to 22 mA output range.
Q: What happens under a short-circuit condition in the T8480C module?
A: Output is limited to 22 mA under 0 Ω load to protect hardware.
Q: What is the maximum disturbance during hot swap of the T8480C module?
A: Current disturbance is limited to ±350 μA (up to 7 s) and ±10 mA (up to 50 ms peak).
