Walk In Stability And Humidity Chamber - Application: Industrial

A walk-in stability chamber PLC specification typically includes details like: temperature and humidity range (e.g., 20C to 60C, 40% to 95% RH), accuracy ( 0.2C, 2% RH), uniformity ( 2C, 3% RH), data logging capabilities, alarm functions, multiple sensor points for mapping, user interface (touchscreen HMI), communication protocols (e.g., Modbus), and compliance with relevant standards like ICH guidelines; all controlled by a programmable logic controller (PLC) system for precise environmental control within the chamber.
The Display or HMI (Human Machine Interface) is a 7 Colour Touch Screen display. It shows values of temperature/ Humidity with Some other
important features:
PLC IP Address setting
Component Working Hours
Password protection for set values & calibration mode
User Manual, Troubleshooting & Preventive Maintenance procedure
Display of Alarms & Its history
Controls access to door opening. User needs to give password to unlock
The door from outside. Control access can be provided to up to 25 users.
Their activity for door access is also tracked.
Audio and visual alarms are generated for
Temperature deviation (High & Low)
Humidity deviation (High & Low)
Door Opening
Utility failure

Mains failure
System unhealthy Error.
The controlling system is fully PLC based system. It consists of PLC
controller, HMI, Relays, Contactors, Overload trip devices, Surge Arresters,
Mains MCB etc.
The control panel has IP22 protection
1. PLC(Programmable Logic Controller)
Complete operations driven through PLC with data storage capacity
of up to 5000 readings on the PLC itself (no additional hardware required)
Records temperature /Humidity readings of all connected sensors
Operates the safety devices
Ethernet communication port for PC communication
Completely modular system
Standard hardware available globally
Generates alarms upon utility failures, fault and deviation in
control parameters
Alarm trans mission to multiple locations
2. Surge Arresters
Removes second and third harmonics form supply line.
Increases the life of control panel components and
electrical components connected to control panel.
Protects electrical components of chamber form in coming surges
and Harmonics.
