System Architecture & Signal Flow
The EI-3203MD-A1 PCB implements a closed-loop analog temperature control path:
- Sensor Input: Thermistor or RTD signal conditioning via precision instrumentation amplifier
- Error Amplifier (DLATC Loop 1): Compares setpoint reference to measured temperature; generates error signal
- Compensation Network (DLATC Loop 2): PID-equivalent analog compensation for loop stability across TEC load variations
- Q2 Output Driver: Linear TEC current driver stage delivering 21.7 mA to thermoelectric module
- PROT Supervisory Circuit: Monitors output current, TEC voltage, and PCB temperature; asserts fault latch on threshold breach

Technical FAQ
Q: Is this a direct replacement for the original Arroyo Instruments 5400-15-28 PCB?
A: Yes. The EI-3203MD-A1 G2/G3 is the current production revision of the 5400-15-28 DLATC/PROT PCB and is a direct form-fit-function replacement.
Q: What TEC load impedance is this module rated for?
A: The Q2 output stage is optimized for standard 1–5 Ω TEC modules at 21.7 mA drive current. Consult the Arroyo Instruments 5400 series datasheet for full load specifications.
Q: Can this PCB be used standalone outside a 5400 mainframe?
A: The module is designed for OEM integration. Standalone operation requires appropriate power supply rails and interface connectors as specified in the 5400 series integration guide.
Q: Do you provide a warranty?
A: Yes. Konmask.com offers a 90-day DOA warranty on all OEM components. Extended warranty available upon request for volume orders.
Q: Can I request a datasheet or test report before purchasing?
A: Yes. Contact [email protected] with your inquiry and we will provide available technical documentation for qualified procurement engineers.
