(ITS-100) Valve limit switch box is the automatic control system to detect the valve state A field instrument, used to open or close the valve position to switch the amount of signal output, the program controller to receive or computer search sampling, after confirmation Execute the next step. The product can also be used as an important control system in the valve chain protection and remote alarm instructions. Design and beautiful appearance, with a three-dimensional position indicator can clearly identify and display the location of the valve, the internal 8-contact circuit board PCB board wiring to facilitate the prevention of short circuit, the control method can be selected according to the site environment proximity switch, magnetic switch and installation Signal feedback device.
Overview: Valve limit switch box is the automatic control system to detect the valve status of a field instrument for the valve to open or close the position of the switch to the signal output, the program controller to receive or computer search sampling, confirm the implementation of the next step program. The product can also be used as an important control system in the valve chain protection and remote alarm instructions.
Features:
◇ three-dimensional position indicator can clearly show the location of the valve.
◇ die-cast aluminum alloy shell, powder coating, compact design beautiful appearance, reduce the valve packaging volume, reliable quality.
◇ Two-wire interface dual 1/2 NPT pipe interface.
◇ signal feedback device.
◇ switch position can be clearly identified by the indicator.
◇ Multi-contact internal circuit board internal 8 contacts (6 for the switch, two for the spiral-shaped electrical conduit link) wiring board meet the micro-switch standard, DPDT switch optional and valve position transmitter (4 ~ 20mA ), Mechanical micro-switches, proximity switches, magnetic switches, etc. and can be used for solenoid valve connection.
◇ fast position cam; adjustable switch adjustable cam through the spline and spring installation; switch cam position without tools can be quickly adjusted.
◇ instead of wiring with PCB board to prevent short circuit.
◇ Ambient temperature: -20 ~ 85 ℃, waterproof and dustproof Protection class: IP67, Explosion-proof grade: ExdII BT6, Eexd IICT6, in line with EN50014 / 50018 standard.
