Overview
The Honeywell TC-IDA161 A is a 16-point AC input module engineered for precise signal acquisition in industrial automation and control applications. This module receives 120VAC signals from discrete input points and efficiently converts them into digital format suitable for processing by a Programmable Logic Controller (PLC) or other automation system. Known for reliable operation in harsh industrial environments, the TC-IDA161 serves as a critical interface between field devices and control systems.
Key Features
- 16-Point Input Configuration: Monitors up to 16 separate 120VAC devices, streamlining control and monitoring processes
- Wide Voltage Range: Accepts 79–132VAC input signals at 50/60 Hz for robust field compatibility
- High Isolation Voltage: 2546 VDC isolation between channels and user-to-system, tested for reliable performance
- Low Power Dissipation: Maximizes backplane efficiency with only 6.0 watts maximum power consumption
- IEC Type 1+ Compliant: Meets international standards for industrial control modules
- Industrial-Grade Durability: Compact design built for demanding environments with reliable signal detection
