Honeywell TC810R1024 Control and Relay Modules

Contact Info

Product TC810R1024

The TC810R1024 is an intelligent addressable relay module manufactured by Honeywell as part of its FlashScan® series . This module provides a Form-C dry-contact relay output that can be activated either manually or through fire alarm control panel programming . It is designed to control auxiliary devices without requiring external power for the relay itself, as it draws power directly from the two-wire Signaling Line Circuit (SLC) .

Technical Specifications

Features

➟Dry-Contact Relay Output for Versatile Control: The module provides a dry-contact (Form-C) relay output that can activate various auxiliary devices such as fans, dampers, door holders, control equipment, and air handling unit (AHU) shutdown systems .

➟Powered Directly by the SLC Loop: The internal circuitry and the relay are powered directly by the two-wire SLC loop, requiring no external power supply for relay operation .

➟Built-in Type Identification: The module automatically identifies itself to the control panel, allowing the panel to differentiate between a module and a sensor address .

➟Integral LED Status Indicator: A green LED blinks each time a communication is received from the control panel and turns steady red when the relay is activated. The LED blink feature can be deselected globally for all devices on the loop .

FAQ

➪ Q1: Does Honeywell support "Hot Swapping" of I/O modules like the DC-TUIO031?

A1: Yes. The Series-C I/O architecture is designed for true hot swap (hot insertion) . If a module fails, you can remove it and install a replacement while the controller and field power remain live. However, you must ensure the replacement module has the same firmware revision as the rest of the rack to prevent automatic synchronization errors during the rebuild process.

➪ Q2: How does Honeywell ensure reliability in harsh industrial environments?

A2: Honeywell offers conformal coating (G3 protection) on select Series-C modules (often indicated by specific part suffixes like -175). This coating protects circuit boards from corrosive gases (sulfur, chlorine, humidity) found in pulp & paper mills, wastewater treatment, and chemical plants . Without this coating, modules can suffer from trace corrosion within 12-18 months in such environments .

➪ Q3: What is the "Honeywell Forge" platform?

A3: Honeywell Forge is the company's industrial IoT and enterprise analytics platform. It collects and contextualizes data from industrial systems to deliver actionable insights for asset performance, cybersecurity, and operational efficiency. The platform is central to Honeywell's "physical AI" strategy, helping customers unlock value from industrial data that is not publicly available .
