POWER SUPPLY
110-240VAC, 11-30VDC
RATING
IP65
The INT4-L is an ideal general purpose weighing indicator for 4 wire and 6 wire load cells. These are among the easiest of programmable panel meters to commission, programmable using the front panel push buttons which may then be locked with a rear switch. The Intuitive series offers high precision with long term reliability, available with AC or DC power supply options.
The main function of the INT4-L is to give a numeric readout of the variable being monitored and includes an excitation power output to power the load cell directly. Various optional output modules are also available to give alarm relay outputs, analogue output or digital communications, or any combination of these options.
The INT4-L has been designed to mount into a protective enclosure which will protect users from contact with power and signal wiring. These panel meters must be installed fully assembled, and must be installed according to local electrical installation rules.
When properly installed, they provide ingress protection to IP65/NMA4X from the front. To view the full specification, please download the product datasheet.
