High Quality Brand New Original Triconex 3721 Analysis Input Module

Description:

The Triconex 3721 is a high-reliability industrial control module launched by Invensys, belonging to the Triconex Safety Instrumented System (SIS) series.

As a digital input card with a Triple Modular Redundancy (TMR) architecture, it complies with international certification standards such as ANSI/ISA-82.02.01-2004 and IEC 61508 (SIL 3). It features 16 digital input channels, each configurable independently, supporting multiple input types including contact closure, voltage signals (0-30VDC), and current signals (0-24mA, sink or source current). Programmable input filters and debounce times are also available for channel settings.

Specifications:

1. Input Voltage: 24V DC (±10%)
2. Input Channels: 16 independent digital input channels; certain models offer 32 differential analog input channels
3. Input Types: Digital inputs support contact closure, 0-30VDC voltage signals, and 0-24mA current signals; differential analog input channels accommodate voltage signals (-5V to +5V, 0V to +10V) and current signals
4. Communication Ports: 2 Ethernet ports, 1 RS-232 port, 1 RS-485 port
5. Input Update Rate: 10ms
6. Resolution: 12-bit or 14-bit programmable resolution for analog input channels
7. Accuracy: < 0.15% of Full Scale Range (FSR) for analog input channels at 0°C to 60°C
8. Common Mode Rejection Ratio (CMRR): Minimum 85dB (DC – 100 Hz) for analog input channels
