Honeywell 8C-PDILA1 Digital Input Module

Honeywell 8C - PDILA1 is a 32-point digital input module for Honeywell Experion LX Series 8 controllers. It provides 24V DC input for monitoring binary devices such as switches, sensors and alarms. It is suitable for non-redundant applications. The following is a detailed introduction:

Main Features

Number of channels: With 32 input channels, 32 digital signal sources can be connected at the same time to meet the monitoring needs of multiple signal sources.

Isolation characteristics: Using optical isolation technology, the system isolation voltage is 1000V AC rms or ±1500V DC, which can effectively prevent external interference signals from entering the control system and improve the stability and reliability of the system.

Wide voltage range: The digital input power supply voltage range is 18 - 30V DC, with strong voltage adaptability, and can work stably under different power supply conditions.

State detection: can accurately detect the state of the input signal, the minimum detection voltage in the "on" state is 13V DC or the minimum detection current is 3mA, and the maximum detection voltage in the "off" state is 5V DC or the maximum detection current is 1.2mA.

Hot-swap support: supports plugging and unplugging of modules under power, which is convenient for system maintenance and upgrades and reduces system downtime.

Technical parameters

Input impedance: 4.2kΩ.

Absolute delay: The absolute delay after input filter and isolation is 5ms±20%.

Module current rating: 95mA.

Field resistance to ensure "on" condition: maximum 300Ω at 15V DC.

Field resistance to ensure "off" condition: minimum 30kΩ at 30V DC.

Application areas

Process control system: commonly used in industrial process control, monitoring various switch signals, such as the opening and closing status of valves, the operating status of pumps, etc., to provide accurate status information for the control system so as to make corresponding control decisions.

Machine automation: in automated production equipment, various digital input signals of the equipment, such as limit switch signals, sensor signals, etc., can be collected to monitor and control the operating status of the equipment, ensure the normal operation of the equipment and the smooth progress of the production process.

Safety system: suitable for safety-related systems, monitoring key digital inputs such as emergency stop buttons and safety door switches, and timely triggering corresponding safety measures when abnormal conditions are detected to ensure the safety of personnel and equipment.

Building automation: in the field of intelligent buildings, it can be used to monitor the switch status of lighting systems, the operating status of air-conditioning systems, the alarm signals of fire protection systems, etc., to achieve centralized monitoring and management of various equipment in buildings, and improve the intelligent level and energy efficiency of buildings.
