Features:

  • Hardened Field Wiring Interface
  • High-Isolation Channel Protection
  • Polarized Keying to Prevent Mismating
The ICS Triplex T9881 accepts up to 16 AWG field wiring with screw terminals, ensuring secure, long-term connections in high-vibration industrial environments. The 6 mm strip length simplifies installation and reduces wiring errors.

With ±1.5 kVdc withstand voltage per channel, the ICS Triplex T9881 isolates the safety controller from field-side faults, preventing electrical damage and improving system uptime. This is critical for maintaining safety loop integrity.

The ICS Triplex T9881 uses coding pins and socket alignment to ensure only compatible analogue output modules (T9481/T9482) can be installed. This eliminates field installation errors and speeds up module replacement.

The T9881 ICS Triplex Analogue Output Termination Assembly may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The ICS Triplex T9881 termination assembly serves as the physical interface between the AADvance I/O module and field actuators. Engineered specifically for T9481/T9482 analogue output modules, this simplex TA simplifies installation by integrating all field wiring connections into a single, compact unit. Its robust design supports reliable 4–20 mA current loops for precise process control.

The ICS Triplex T9881 features 8 individual field wiring terminals, accepting conductors up to 1.31 mm² (16 AWG) with a 6 mm strip length. Each channel is isolated to withstand ±1.5 kVdc for one minute, protecting the safety controller from field-side faults. The module locking mechanism and polarization keying prevent incorrect mating, reducing installation errors.

Built for industrial environments, the ICS Triplex T9881 operates reliably across a wide temperature range and is certified for use in hazardous locations (Class I, Div 2). As part of the Rockwell Automation AADvance platform, this termination assembly supports safety integrity levels up to SIL 3 when paired with the appropriate output configuration, making it a trusted choice for critical process safety applications.
