Features:
- Low Level Analog Input field termination
- Series C Input Output Termination Assembly format
- Separate termination and plug-in electronics arrangement
DC-TAIL51 51307601-176 forms the fixed wiring interface for low-level analog channels in a Series C cabinet.
The IOTA layout of DC-TAIL51 51307601-176 keeps field conductors landed while the associated LLAI electronic module is handled as a separate component.
DC-TAIL51 51307601-176 must be identified by the complete PWA number because nearby LLAI assemblies can use different connector or electronics combinations.
The Honeywell DC-TAIL51 51307601-176 Low Level Analog Input IOTA is listed as Discontinued / Obsolete by OEM. Apter Power can support sourcing, documentation, and exact-part review.

Temperature-sensor termination
- Thermocouples: DC-TAIL51 51307601-176 accepts low-level thermocouple signals through the LLAI path.
- RTDs: Resistance temperature detectors are supported by the same sixteen-channel IOTA.
- Module pairing: The IOTA is documented for use with the CC-PAIL51 input module.
- Millivolt range: The nominal thermocouple span is -20 mV to +100 mV.
Per-channel electrical separation
- Isolation count: All sixteen DC-TAIL51 51307601-176 channels are fully isolated.
- Common-mode limit: The maximum published value is ±250 VDC or VAC RMS.
- Input loading: Thermocouple channels present 1 MΩ impedance at dc.
- Channel structure: Isolation is maintained individually rather than by a single shared input group.
Input response boundaries
- Scan interval: DC-TAIL51 51307601-176 acquires each input on a one-second schedule.
- Passband: The published response extends from dc to 4.7 Hz at -3 dB.
- TC protection: Thermocouple inputs tolerate -10 V to +10 V without damage.
- RTD protection: RTD inputs tolerate -1 V to +2 V at 100 mA without damage.
Published error characteristics
- Gain error: DC-TAIL51 51307601-176 is specified at 0.050% of full scale maximum.
- Temperature stability: The maximum published coefficient is ±20 ppm/°C.
- Long-term drift: Honeywell lists a 500 ppm long-term drift value.
- Measurement context: These limits apply to the documented low-level analog input path, not to unrelated Series C modules.
