Honeywell 51202343-001 Alarm Cable

Overview

The Honeywell 51202343-001 Alarm Cable is designed for use in control systems that require alarm reporting through digital input (DI) channels. It is commonly used with Honeywell’s Series C 24V digital input I/O modules and associated IOTAs to facilitate the connection of power supply alarm contacts to 24V DC digital inputs on the IOM (Input/Output Module).

Key Features

Cable Length: 12 feet
Functionality: Used to connect power supply alarm contacts to 24V DC digital inputs.
System Integration: The cable connects with DI 24V modules (CC-TDIL01, CC-TDIL11) for alarm generation and reporting.
Alarm Configuration: Digital input channels are incorporated into the control strategy to trigger and report alarms based on their process values (PVs).

Control Strategy Overview

A typical alarm control strategy involves the following components:

Control Module: Contains DI channel blocks where each PVs (outputs) are connected to a PVFL input of a FLAGARRAY block that is configured for alarming.
Normal Condition: The normal condition of the alarm input is ON.
Alarm Triggering: Alarms are triggered when the PV deviates from its normal condition, based on the configured thresholds.

Prerequisites

Modules: The system must have Series C 24V digital input I/O modules and associated IOTAs installed and configured.
Alarm Cable: Ensure you have the Honeywell 51202343-001 alarm cable (12-foot length) to connect the power supply alarm contacts to the 24V DC digital inputs.

Installation Steps

Connecting the Alarm Cable:
- Plug the connection end of the alarm cable into the alarm connection on top of the power supply.
Wiring Configuration:
- Connect the twisted pair wires to terminal block 1 on the DI 24V IOTA. Ensure that the alarm pins are correctly connected as per the specified configuration.
