Current Analog Input Module 8AI

CT-3268 Current Analog Input Module 8AI The CT-3268 8-channel current analog input module by ODOT Automation is a high-precision, bipolar acquisition solution engineered for advanced industrial measurement and control applications. It directly addresses global engineering challenges in bidirectional current signal handling, high-density I/O integration, and inadequate surge protection.  Supporting 8 independent channels, the module can be configured for 0–20mA, –20–0mA, or ±20mA input ranges—enabling full-scale acquisition of bipolar sensor signals such as those from torque transducers, bidirectional flow meters, or position feedback devices. With 15-bit single-ended bipolar resolution, it accurately captures even subtle signal variations.  The module accepts 2-wire active current-output sensors (requiring external loop power) and connects directly to standard industrial transmitters. Critical reliability features include magnetic insulation between the internal backplane bus and fiel…
