Product Overview

The TC-PIL081 is a Honeywell temperature input module with 8 input channels referenced to a single common. This module is configurable for input channel groups 0 to 3 and 4 to 7, supporting thermocouple or RTD sensor types. It is designed for demanding industrial automation environments requiring precise temperature measurement and intrinsically safe operation.

Technical Specifications Analysis

The TC-PIL081 offers a 16-bit resolution with a response time of 4 ms. It supports thermocouple types E, J, K, N, R, S, and T with accuracy of +/- 0.5% of mV input for E, J, K, N types and +/- 0.8% for R, S, T types. RTD sensor types include Pt 100, Pt 200, Ni100, Ni200, Ni120, and Cu10 with accuracy of 0.1% of span for most types. The module operates within an ambient temperature range of –20°C to 70°C and stores from –20°C to 100°C. It has a power consumption of 0.19 power supply unit load and dissipates 1.6W. The weight is 0.247 kg (0.54 lb) and dimensions are 76 x 94 x 46 mm (3.0 x 3.7 x 1.8 inches).

Application Scenarios & Usage Methods

In oil and gas refineries, the TC-PIL081 monitors temperature in distillation columns using thermocouple types K and J. Users configure the filter cutoff to 2 Hz to reduce noise. In chemical plants, it tracks RTD sensors for reactor temperature control, employing 3-wire measurement to compensate for lead resistance. For power generation, the module measures turbine bearing temperatures with Pt 100 sensors, setting the temperature format to Celsius and enabling fault detection for sensor breakage.

Installation Guide & Packing List

Mount the module on a terminal base with keyswitch position 2. Ensure intrinsically safe power is supplied through the base. Use shielded multicore cable with isolation greater than 500V per channel for EMC compliance. The packing list includes the TC-PIL081 module and documentation. No additional accessories are included.

Purchasing Advice

When selecting the TC-PIL081, verify that your application requires 8 input channels and supports the specified thermocouple or RTD types. The module is suitable for hazardous areas with CENELEC classification II (1) 2G EEx ia/ib IIB/IIC T4. For reliable supply, consider purchasing from PetroPartsOnline, a trusted source for industrial automation parts.

Repair & Maintenance Tips

Periodically inspect the module for dust or corrosion, especially in G3 pollution environments. Clean with a dry cloth and store within –20°C to 100°C when not in use. Avoid exposing the module to relative humidity above 95% non-condensing. Check for loose connections on the terminal base to maintain signal integrity.
