Product information

32-channel “volt-meter on steroids” that turns your Tricon into a SIL-3 data laboratory

1. 3721 = 32 × Differential “Lab-Grade” Inputs

Need to watch 32 pressure transmitters, flow elements or ±10 V servo valves in true real-time? 3721 gives every single one its own 16-bit A/D, DC-coupled, 120 dB CMRR and 10 ms refresh. No multiplexing, no phase-lag, no kidding.

2. TMR Inside, Noise Outside

Triple converters vote on every sample; bad channel auto-disqualified and flagged. Result: 0.05 % FS accuracy even when your VFD is screaming at 50 m away. Certified IEC 61508 SIL 3 by TÜV, so the safety auditor smiles instead of writes.
