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.
