The following is a deep technical analysis of SP1406 (industrial grade signal isolator/safety barrier), combined with the common designs of mainstream brands such as MTL, P+F, and Jinshengyang, covering core functions, safety certification, selection logic, and typical fault handling solutions:
1、 Basic specifications and safety certification
Parameter specifications
Model SP1406 (universal model, representing 1-in-2-out architecture)
Input signal 4-20mA/HART (two-wire transmitter)
Output signal dual channel isolation: 4-20mA+relay alarm
Isolation level b/output/power three terminal isolation 2500V AC
Explosion proof certification ATEX/IECEx Ex ia IIC T6 Ga (intrinsic safety type)
Accuracy ± 0.05% F.S @ 25 ℃
Response time ≤ 50ms (analog)/≤ 10ms (relay)
Power supply 20-35V DC (loop power supply)
Power consumption ≤ 1.8W
?? Safety boundary beters (for intrinsic safety calculations):
Ui=28V DC, Ii=93mA, Pi=0.65W
Ci=5nF, Li=10μH
2、 Circuit architecture and signal flow direction

B -->C [Main output: 4-20mA -->DCS/PLC]
B -->D [Secondary output: Relay contact -->Sound and light alarm]
B -->E [HART transparent transmission -->Handheld device]
Core isolation technology:
Magnetic electric isolation: b signal → magnetic coupling modulation → demodulation output (eliminating ground loop interference)
Relay isolation: Optical MOS solid-state relay (without mechanical contact wear)
Triple isolation barrier: thick film ceramic substrate+epoxy resin encapsulation
3、 Installation and wiring specifications

-Signal b -0.5-2.5mm 2
OUT1+main output current+0.5-1.5mm 2
OUT1- Main output current -0.5-1.5mm 2
ALM C relay common terminal 0.75-2.5mm 2

plaintextCopy Code
Safe Zone [DCS]<-->[Safety Barrier]====※===[SSP406]<-->Hazardous Zone [Transmitter]
(Safety barrier beters: Uo ≤ 28V, Io ≤ 93mA)
?? Key rules:
Dangerous area cables must be armored, shielded, and single ended grounded
The distance between the safety barrier and SP1406 is ≤ 5 meters (to avoid excessive distributed capacitance)
4、 HART transparent transmission configuration
Enable HART communication
plaintextCopy Code
1. Jumper setting: Place JP1 in the HART b
2. Wiring verification: Connect a 250 Ω resistor in parallel at both ends of OUT1+/-
3. Handheld device connection: Connect OUT+and OUT - (power-off operation required)
Troubleshooting of Communication Malfunctions
Phenomenon solution
Intermittent check of circuit resistance for HART communication: ≥ 230 Ω and ≤ 600 Ω
The handheld device cannot recognize the measurement of HART signal peak to peak value ≥ 0.8V PP
Communication interference is significant, and a 0.22 μ F capacitor filter is connected in parallel at the OUT end
5、 Alarm function configuration
Relay b logic
Default value for beter setting range
Alarm point 0-110% range 22mA (high alarm)
Dead zone 0.5-10% range 1%
Delay 0.1-60 seconds 2 seconds
Action direction high/low/disconnection high
?? Principle of wire breakage detection:
Input current<3.6mA for 3 seconds → Relay b
6、 Fault Diagnosis Quick Check Table
Diagnostic steps for the meaning of fault codes
ALM LED stays on, b exceeds range/disconnects, measurement b voltage (normal) 1-5V@250 Ω)
Output freeze internal fuse blown, check if the terminal is short circuited (resistance>1M Ω)
Large output fluctuation, breakdown test of isolation diaphragm, isolation impedance (failure occurs when<100M Ω)
HART failure jumper error confirmation JP1 is not placed in the "TEST" b
7、 Compatible alternative solutions
International brand benchmarking
Differences in Model and Brand
MTL7741 MTL supports FF bus
KFD2-STC4-EX2 P+F dual channel independent alarm
SP1406 Jinshengyang wide temperature design (-40~85 ℃)
Domestic preferred solution
plaintextCopy Code
Recommended model: Chenzhu GZ2406-EX
Replacement steps:
1. Function mapping:
ALM C/NO of SP1406 → AL1/AL2 of GZ2406
2. Parameter adjustment:
The alarm dead zone has been changed from 1% to 0.5% (requires entering the menu settings)
8、 Whole life cycle management
Key maintenance nodes
Periodic maintenance project standards
1-year insulation strength test b shell ≥ 100M Ω @ 500V
2-year accuracy calibration error ≤± 0.1% F.S
5-year aging inspection of sealant with no cracks/yellowing (visual inspection)
Mandatory replacement of electronic components for 10 years, expiration of lifespan
