Designed for demanding environments, the 3700A offers high precision, robust performance, and advanced diagnostic capabilities, making it an ideal choice for critical industrial applications.

Key Features of the TRICONEX 3700A

The 3700A module stands out with its exceptional specifications:

Voltage Range: 0-5V with a tolerance of +6%, ensuring accurate signal acquisition.

High Resolution: 12-bit resolution for detailed analog-to-digital conversion.

Input Points: 32 differential, DC-coupled inputs for versatile connectivity.

Accuracy: Maintains <0.15% of Full Scale Range (FSR) from 0° to 60°C, guaranteeing consistent performance in varying temperatures.

Common Mode Rejection: -80 dB (DC-100Hz), minimizing noise interference.

Overrange Protection: Handles up to 150 VDC/115 VAC continuously, safeguarding against voltage spikes.

Comparison with Other TRICONEX Models

The 3700A belongs to a family of high-performance analog input modules, each tailored for specific industrial needs. Below is a comparison with its counterparts, the 3701 and 3703E:

Feature	3700/3700A	3701	3703E
Voltage Range	0-5V (+6% for 3700A)	0-10V	0-5V or 0-10V¹ (+6%)
Input Points	32, diff, DC-coupled	32, diff, DC-coupled	16, diff, isolated
Isolation	No	No	Yes (±200V peak)
Update Rate	55 ms	55ms	50 ms
Common Mode Rejection	-80 dB (DC-100Hz)	-80 dB (DC-100Hz)	-90 dB @60Hz, -100 dB @DC
Current Range	0-20 mA, 250Ω shunt	0-20 mA, 500Ω shunt	0-20 mA, 250Ω (5V) / 500Ω (10V)

Choosing the Right Module

3700A: Best for low-voltage (0-5V) applications requiring high channel density (32 inputs) and basic noise immunity.

3701: Ideal for higher voltage (0-10V) systems with similar channel count but no isolation.

3703E: The premium choice for isolated inputs (16 channels), superior noise rejection, and extreme common-mode voltage tolerance (±200V).

Enhanced Diagnostics and Durability

All three modules feature diagnostic indicators (Pass/Fault/Active) and robust overvoltage protection. The 3700A is marked by its yellow color code, while the 3701 uses light yellow and the 3703E mustard yellow for quick identification.

Ideal for Critical Applications

With fast update rates and high accuracy, these modules are perfect for industries such as oil and gas, chemical processing, and power generation, where precision and safety are paramount.

TRICONEX’s commitment to innovation ensures that these modules deliver unmatched performance, reinforcing their reputation as trusted solutions for industrial automation.
