Key Features

• Supports 8 independent channels configured specifically for accurate 3-wire RTD temperature sensor monitoring.
• Performs hardware-level sensor linearization and conversion directly to Centigrade or Fahrenheit on the module.
• Provides clean signal performance via a configurable mains frequency filter providing a sharp notch filter at 50 Hz or 60 Hz.
• Features integrated continuous hardware diagnostics checking for open-circuit, short-circuit, and sensor ground faults.
• Delivers precise 14-bit signal processing resolution optimized for sensitive thermal tracking applications.

Installation Notes

• Mount the module securely onto an approved S800 Module Termination Unit (MTU) including compact or extended bases like TU810V1 or TU830.
• Connect all process field wiring with shielded cables using 3-wire configuration schemas to maintain required measurement accuracy.
• Ensure that all connected RTD sensor elements are explicitly isolated from ground loops.
• Verify that the MTU mechanical keying code matches position AF perfectly before insertion to prevent equipment damage.
