Designed specifically for Triconex safety systems, the Triconex 3721C Differential analog input module is a coated module that provides a reliable solution for critical applications requiring high integrity and high reliability analog input processing. The module is part of the broader Triconex family of safety controllers and modules, known for its three-module redundancy (TMR) technology, which ensures higher availability and safety integrity levels (SIL) up to SIL3.
DIFFERENTIAL ANALOG INPUT 3721C
Manufacturer: Invensys Triconex, now part of Schneider Electric.
Model: 3721C.
Type: Differential Analog Input Module.
Voltage Range: Supports both unipolar (0 to 5 VDC) and bipolar (-5 to +5 VDC) inputs with a tolerance of ±6%.
Number of Input Points: Equipped with 32 differential, DC-coupled input channels, allowing for precise measurement of analog signals.
Resolution: Offers programmable resolution between 12 bits and 14 bits, catering to varying application requirements for precision.
Accuracy: Provides high accuracy with less than 0.15% of full-scale range (FSR) error within an operating temperature range of 0° to 60° C.
Common Mode Rejection: Features excellent common mode rejection of -85 dB from DC to 100 Hz, minimizing interference from common mode signals.
Input Overrange Protection: Designed to withstand continuous overvoltage conditions up to 150 VDC/115 VAC, enhancing reliability in harsh environments.
Physical Characteristics: The module has dimensions of approximately 2.2cm * 40.8cm * 40cm and weighs about 2.06kg.
Country of Origin: Manufactured in the United States.
