Features:

  • Interface Between the Analog Field Instruments and C300 Controller Backplane
  • Integrates 16-Channel Differential AI Acquisition with Redundant IOTA Support
  • Functions in Conjunction with the Series 8 and C300 Process Control Systems
The 8C-TAIDB1 51307133-175 operates as the AI IOTA Redundant Module in a C300 rack, providing reliable analog input signal conditioning and conversion for all channels within the module. It continuously accepts incoming analog signals (1–5 VDC voltage or 4–20 mA current via 250 Ω resistor) and converts these to digital data with a 16-bit ADC, distributing this data through the IOTA backplane to support steady state operation of the C300 controller and associated I/O modules. Seamless channel operation is standard with the 8C-TAIDB1, and the redundant IOTA architecture allows seamless switchover to a backup path in the event of a primary signal path failure. The 8C-TAIDB1 51307133-175 has incorporated G3-grade conformal coating and universal differential input capability within the Series 8 IOTA rack.

The 8C-TAIDB1 51307133-175 provides essential analog input functions common to the entire IOTA assembly, and is a critical component of the control loop path, directly affecting the proper, normal operation of the overall process control system. One or two 8C-TAIDB1 51307133-175 modules are deployed per IOTA base depending on the desired redundancy level. The 8C-TAIDB1 occupies a 12-inch redundant IOTA slot in the rack and is always mounted on the dedicated AI IOTA base.

For Dual Redundant IOTA applications, the C300 System requires a second 8C-TAIDB1 51307133-175 module installed in the redundant slot. In addition to standard single module operation, the redundant configuration also performs automatic switchover. The C300 dual IOTA configuration executes failover using the internal circuitry specified in the IOTA options. Using this method, the redundant IOTA system continually monitors the health of both modules. If the system detects that the primary 8C-TAIDB1 51307133-175 is no longer providing stable output (outside configured accuracy/tolerance levels), it will automatically transfer the load to the secondary module and place an event in the System Event List.

The 8C-TAIDB1 51307133-175 Honeywell AI IOTA Redundant Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
