Overview
KSA-2011-EX switch input isolation safety barrier, switch input, relay output isolation safety barrier, receives switch or proximity switch inputs from hazardous areas, and transmits them to the safety area relay output through safety barrier isolation. Each channel can be independently set to input and output same phase or opposite phase control, and also has input line fault detection alarm indication function.
Product Details
KSA-2011-EXSwitch input isolated safety barrierOverview
thatSwitch input isolated safety barrierReceive switch/proximity switch inputs from the hazardous area side, isolate them through safety barriers, and transmit them to the safe area output. Equipped with proximity switch fault detection and relay output positive and negative action setting functions.
KSA-2011-EXSwitch input isolated safety barrierMain technical parameters
Installed in a safe place, it can be connected to intrinsically safe instruments located in Zone 0, Zone 1, Zone 2, IIC, IIB, IIA, T4~T6 hazardous areas. Power supply voltage: 20-32V DC
Current consumption: (24V power supply, when relay contacts are closed)
≤ 30mA, one in, one out
≤ 40mA, one in two out/two in two out
Output characteristics of safety side relay:
Response time: ≤ 10ms
Drive capability: 250V AC, 2A or 30V DC, 2A
Load type: resistive load, hazardous side input:
Signal: Dry contact or NAMUR type proximity switch Open circuit voltage: ≈ 8V Short circuit current: ≈ 8mA
Input and output characteristics (set to in-phase control):
On site switch closed or input circuit current>2.1mA, output relay closed, channel yellow indicator light on
On site switch open circuit or input circuit current ＜ 1.2mA, output relay open circuit, channel yellow indicator light off
KSA-2011-EXSwitch input isolated safety barrierInstallation precautions
Isolation safety barriers should be installed in non hazardous areas
The cross-sectional area of the soft copper wire leading from the isolated safety barrier to the site (hazardous area) must be greater than 0.5mm2
The insulation strength of the connecting wire should be greater than 500V
When conducting separate power on debugging of isolated safety barriers, attention must be paid to the model, power polarity, voltage level, and labeling on the wiring terminals of the isolated safety barrier shell
It is strictly prohibited to use a megohmmeter to test the insulation between isolated safety barrier terminals. When checking the insulation of the system circuit, all isolated safety barriers should be connected first, otherwise it will cause the internal rapid fuse to melt
If the internal module of the isolated safety barrier is damaged and needs to be replaced, it needs to be repaired together with the manufacturer, and can only be put back into operation after maintenance
