PHD-22HF-2727
Overview
H series backplane mounting isolated safety barriers at detection side: PHD-22HF-2727, digital input ampo output, dual input ampo dual outputs.
Ing isolated barrier malyari neng i-convert ing proximity switch ampo ing contact input keng hazardous area keng relay contact signal ampo i-transmit ne keng safe area.
Ing output relay atin yang selection switch ning "ON/OFF" a sitwasyun. Dagdag pa, atin yang input signal short-circuit o open-circuit alarm indication, ing circuit mamye yang kuryenti para keng input sensor.
Ing produktung ini mangailangan yang independenting power supply.
Ing signal status indicator maka set ya keng red ampo yellow a sulu para ipabalu ing working status ning output relay, nung para ya keng alarming kanita ing sulu maputi ya, kabang normal yang operasyun ing sulu yellow ya.
| Supply voltage | 20~35VDC, power consumption |
| Input signal | Ibayu ing contact o Proximity switches (NAMUR) |
| Supply voltage ning sensor keng site | 8V |
| katangian ning signal input | On-site input current: >2.1mA, ing indikasyon ON; On-site input current: |
| Output keng ligtas a lugal | Response time: 20ms, driving capability: 250VAC/2A, 30VDC/2A lalam ning resistive load |
Ing output normal yang "Open"/"Closed" | Nung ing dial switch K1, K3 atyu ya keng "ON" side, ing relay output "OFF" ya. |
| Nung ing dial switch K1, K3 atyu ya keng "OFF" side, ing relay output "ON" ya. | |
| Nung ing dial switch K2, K4 atyu ya keng "ON" a gilid, ing circuit mamili yang magpakit a red light LFD alarm function | |
| LFD | On-site input current>7mA, short-circuit alarm (SC) , on-site input current |
| Para keng switch contact input, nung kailangan ing disconnection detection function, ing 22KΩ resistor kailangan yang makakonekta parallel kareng adwa nang wakas ning switch (Paki lawan me ing switch contact II keng wiring diagram king lalam) | |
| Bilang ning input ampo output | 2 inputs 2 outputs |
| Applicable field equipments | Dry contact o NAMUR proximity switch agpang keng DIN 19234 standard |
| Parameter ning temperatura | Temperatura ning obra: -20°C~+60°C, temperatura ning pamitipun: -40°C~+80°C |
| Relatibung humidity | 10%~95% RH alang condensation |
| Dielectric strength | pilatan ning intrinsically safe side ampo non-intrinsically safe side (≥3000VAC/min); pilatan ning suplay ning kuryenti ampo ing e ligtas a terminal (≥1500VAC/min) |
| Insulation resistance | ≥100MΩ (pilatan ning input/output/power supply) |
| Sukat | Kapal 15.8mm * lapad 104.8mm * katas 116.1mm |
| Electromagnetic compatibility | Agpang keng IEC 61326-1 (GB/T 18268), IEC 61326-3-1 |
| Markang e malyaring sabog | [Exia Ga]IIC, [Exia Da]IIIC |
| pamantayan ning sertipikasyun | GB/T 3836.1-2021, GB/T 3836.4-2021 |
| katawan ning sertipikasyun | CQST(China National Quality Supervision and Test Center for Explosion Protected Electrical Products) |
| Certified parameters (pilatan da reng terminal 1-2,4-5) | Um:250VAC/DC,Uo=10.5VDC,Io=14mA, Po=37mW,Co=2.4μF,Lo=165mH. |
| Kailangan king lugal ning pamag-install | Maka-install ya keng safe zone, malyari yang ikonekta kareng intrinsic safety instruments kareng hazardous a lugal angga keng Zone 0, IIC, Zone 20, ampo IIIC |
| MTBF | ≤100000h |
Line Fault Detection (LFD)
Ing Line Fault Detection (LFD) metung yang switch a malyaring pilinan ning gagamit keng babo ning module at mipalabas ya keng LED. nung atin yang akit a line fault, ing line fault relay makasara ya at ing channel output relay makadiskonekta ya. Short circuit alarm (SC) para keng field input current >7mA; open circuit alarm (LB) para keng field input current
