TRICONEX 3721N Analog Input Module

Parameter
Channel: 32 differential DC coupled inputs, two independent 1 × 20 multiplexers.
Input range: 0-5 VDC (unipolar), -5 to+5 VDC (bipolar); An external 250 Ω resistor can support 0-20 mA.
Resolution: 12/14 bit programmable.
Accuracy: ± 0.15% FS (0-60 ° C).
Input impedance:>1 M Ω (voltage mode).
Common mode rejection: -85 dB (DC-100 Hz).
Update cycle: 10 ms (single channel).
Overvoltage protection: 150 VDC/115 VAC continuous.
Isolation: There is no isolation between channels; Leg isolation of 200 k Ω (typical).
Power supply: 5 VDC (backplane), with a power consumption of approximately 5 W.
Temperature: -40 ° C~+70 ° C (industrial grade).
Coating: Three proof coating (moisture-proof/anti mold/anti salt spray), suitable for high humidity, dust, and corrosive environments.

Core functionality
TMR redundant acquisition: Each channel has 3 independent ADCs for synchronous sampling, hardware voting output, and single channel fault free disturbance.
Differential anti-interference: differential input+high common mode rejection, suitable for strong electromagnetic interference fields (such as power plants and refining equipment).
Flexible signal adaptation: Software configuration for voltage/current mode, supporting thermocouples (with 3721-ST terminal fittings), RTDs, and 4-20 mA transmitters.
Intelligent diagnosis: self diagnosis of wire breakage/short circuit/over range/power supply abnormality, LED status indication+system log, supports online replacement.

Application
Petrochemical industry: reactor/tank pressure/liquid level safety monitoring, F&G fire and gas system
Electricity: Steam turbine/boiler SIS protection, excitation system signal acquisition
Oil and gas: emergency cutoff of long-distance pipelines, compressor protection
