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 input/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 parameters (for intrinsic safety calculations):
Ui=28V DC, Ii=93mA, Pi=0.65W
Ci=5nF, Li=10μH
2、 Circuit architecture and signal flow direction

A [Two wire transmitter] -->| 4-20mA+HART | B (SP1406 input isolation)
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: input 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

+Transmitter power supply+0.5-2.5mm 2
-Signal input -0.5-2.5mm 2
OUT1+main output current+0.5-1.5mm 2
OUT1- Main output current -0.5-1.5mm 2

plaintextCopy Code
Safe Zone [DCS]<-->[Safety Barrier]====※===[SSP406]<-->Hazardous Zone [Transmitter]
(Safety barrier parameters: 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 position
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 action logic
Default value for parameter 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 action
6、 Fault Diagnosis Quick Check Table
Diagnostic steps for the meaning of fault codes
ALM LED stays on, input exceeds range/disconnects, measurement input 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" position
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 input 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
