Set of components for the study of a All or Nothing temperature regulation loop with a PT100 temperature sensor and 4-20mA signal. These solutions of regulation are delivered with all the necessary safety leads, a user’s manual for each component and also wiring diagrams.
EDUCATIONAL OBJECTIVES
• Understanding and wiring of a regulation chain All-Or-Nothing.
• Studying, setting, control of a All-Or-Nothing regulator.
• Understanding of the link resistance / temperature as measuring
principle.
The regulator unit controls in all-or-nothing the supply of the load
from a 4-20mA signal.
EXAMPLES OF USE Enter the order value directly in the regulator.
When the 4-20mA signal from the sensor reaches the order value,
the state of the dry contact changes and opens (or closes) the supply
circuit of the load (programming of the contact state: NO or NC).
Supply of the unit in 230V (power cord)
The communicating version has the same features and includes in
addition a possible programming by software and retrieving datas
(files + curves).
• 4-20mA input on safety sockets 4mm
• 10 000 counts configurable display
• Settings of the display :
- For 4mA input, the user can choose the value displayed between -1000 and 9999
- For 20mA input, the user can choose the value displayed between 0 and 9999.
• Setting of the decimal point
• Example of a 5bars converter: :
- For 4mA, display indicates 0.000
- For 20mA, select 5.000 (for the maximum value)
• Output: 250VAC / 0.5A relay on safety sockets 4mm
• Output: 12VDC (allow the wiring a 4-20mA loop without an external supply)
• Alarms: high and low, relay output on safety sockets 4mm
• Settings: offset, hysteresis, gain, filter
• Dimensions: 145 x 185 x 100 mm
