Features:
- True SIL 3 Scalability Without Hardware Change
- Intelligent Field Line Monitoring Reduces False Trips
- Hazardous Area Ready with Global Certifications
The ICS TRIPLEX T9401 supports simplex, dual (1oo2D), and triple (2oo3D) voting configurations using the same module. This allows you to upgrade from fail-safe to fault-tolerant operation by simply adding identical modules and changing the termination assembly (T9801→T9802→T9803), no application rewrite required.
Each channel on the ICS TRIPLEX T9401 continuously measures input voltage and distinguishes between valid ON/OFF states, open-wire faults, short circuits, and out-of-range conditions. The module reports both digital status and analog voltage value to the processor, giving maintenance teams diagnostic evidence before a nuisance trip occurs.
The ICS TRIPLEX T9401 carries ATEX, IECEx, and UL Class I Division 2 certifications (File E251761), enabling direct installation in Zone 2/Division 2 environments. Combined with an IP54 tool-accessible enclosure, the module meets the strictest requirements for oil & gas, chemical, and power generation sites without external barriers.
The T9401 ICS-TRIPLEX Digital Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Emergency Shutdown Systems (ESD):The ICS TRIPLEX T9401 monitors field contacts (pressure switches, emergency pushbuttons) and triggers safety actions with SIL 3 integrity. Its dual/TMR capability ensures no single point of failure disables the shutdown function.
- Fire & Gas Detection (F&G):With line monitoring for open/short circuits, the ICS TRIPLEX T9401 is ideal for smoke detectors, manual call points, and flame sensors. It can distinguish between a genuine alarm and a wiring fault, reducing false plant evacuations.
- Burner Management Systems (BMS):Boilers and furnaces require fast, predictable input response. The ICS TRIPLEX T9401 provides <5ms update and 1ms SOE timestamping, meeting NFPA 85/86 requirements for flame scanner and limit switch monitoring.
- Critical Process Interlocks:For high-speed packing lines, compressors, or turbine auxiliaries, the ICS TRIPLEX T9401 offers redundant input voting (1oo2D) to prevent spurious trips while maintaining fail-safe behavior.
- Temperature Extremes:Operates from -25°C to +60°C (hazardous area) and -25°C to +60°C (non-hazardous), suitable for outdoor cabinets in arctic or desert sites.
- Humidity & Condensation:10–95% RH non-condensing; conformally coated (MIL-I-46058C) to resist moisture and airborne contaminants.
- Pollution Degree:Designed for Pollution Degree 2 environments per IEC 60664-1 (typical control rooms and light industrial). Requires IP54 enclosure for Zone 2/Div 2.
- Vibration & Shock:Withstands 0.5g endurance vibration and 15g shock (11ms half-sine), meeting IEC 61131-2 requirements for skid-mounted or compressor-adjacent installation.
- Functional Safety (SIL):Certified by TÜV Rheinland to IEC 61508:2010 for use in safety functions up to SIL 3 (simplex, dual, or triple configurations). Baseplate diagnostics achieve >90% safe failure fraction (SFF).
- Hazardous Locations:ATEX: Ex ec IIC T4 Gc (Zone 2). IECEx: UL 12.0032X. UL: Class I, Division 2, Groups A, B, C, D (File E251761). Requires vertical mounting and 85°C-rated wiring.
- EMC & Electrical:Tested to EN 61326-1 Class A, EN 61131-2, and EN 54-4. Provides ±1.5kVdc isolation between channels and backplane, eliminating ground loop problems.
- Environmental Compliance:RoHS compliant; WEEE recycling scheme available through Rockwell Automation. No hazardous substances above threshold limits.
