Honeywell TC-PIA081 Analog Current Input Module

Overview

The TC-PIA081 is an 8-point analog current input module designed for use with 2-wire and 3-wire transmitters, featuring high accuracy and intrinsically safe design. It has been withdrawn from sale and replaced by the TC-PIA082. This module is ideal for industrial automation applications that require precise current measurement with high safety standards.

Key Features:

• Input Channels: 8 single-ended input channels.
• Accuracy: 0.1% of the signal range.
• Temperature Drift: 50 ppm/°C.
• Response Time: 4 ms to 99% of the final value.
• Resolution: 16 bits.
• Input Range:
  • Signal: 4 to 20mA
  • Extended: 2 to 22mA
  • Voltage: >15V @ 22mA.
• Intrinsically Safe: Compliant with Europe’s II (1) 2G EEx ia/ib IIB/IIC T4 (CENELEC).
• Transmission Error: 0.1% of output signal range at 293K (20°C/68°F).
• Galvanic Isolation: Input to backplane bus and power supply.

Technical Specifications:

• Input Type: 2-Wire and 3-Wire transmitters.
• Permissible Field Circuit Values:
  • 2-Wire Input: Uo = 23.7V, Io = 92.5mA, Po = 548mW.

• Filter Cutoff: Configurable for input channel groups 0-3 and 4-7 (0.5, 1, 2, 4, 10 Hz).
• Alarm Indicators:
  • Overrange, underrange, transmitter alarm, and lead breakage alarm (configurable for each channel).
  • Lead Breakage: Alarm signal via backplane bus and flashing red LED for faults.

Operating Conditions:

• Ambient Temperature: –20°C to 70°C (–4°F to 158°F).
• Storage Temperature: –20°C to 100°C (–4°F to 212°F).
• Relative Humidity: Max 95%, non-condensing.
• Protection Class: IP20 (installation in the field requires separate housing with IP54 or better).

Physical Characteristics:

• Weight: 0.203 kg (0.45 lb).
• Dimensions (H x W x D): 76 mm x 94 mm x 46 mm (3.0 x 3.7 x 1.8 inches).
