Overview

The Honeywell 8C-TDILA1 is a high-density digital input module designed for industrial automation and process control applications. Part of Honeywell's Experion PKS Series 8 I/O family, this module enables reliable acquisition of discrete signals from field devices such as switches, sensors, and relays.

It features 32 input channels, with the first 16 channels configurable for pulse accumulation and frequency measurement, while channels 17–32 function as standard digital inputs. The module also includes optical isolation for improved noise immunity and galvanic isolation rated at 1000 VAC RMS or ±1500 VDC, ensuring safe operation even in electrically noisy environments.

With its DIN rail mounting and wide operating temperature range of –40°C to +70°C, the 8C-TDILA1 is ideal for use in critical industrial environments such as refineries, chemical plants, power generation, and water treatment.

Technical Data

Typical Applications

• Discrete Signal Acquisition: Captures on/off states from switches, pushbuttons, and limit sensors.

• Pulse Accumulation: Counts pulses from flow meters, encoders, and other frequency-based devices.

• Industrial Automation: Used in packaging, assembly, and material handling systems.

• Process Control: Monitors equipment status in chemical, pharmaceutical, and food processing plants.

• Power Generation: Tracks turbine and boiler control signals for safe operation.

For example, in a water treatment facility, the 8C-TDILA1 can monitor pump status and count pulses from flow sensors to ensure accurate flow control and system diagnostics.
