The 65M-3600-CT-T is a 16-channel analogue current input module for ioPAC 6500 Series 65M modular controller systems. It is designed for industrial applications that need to acquire current-based field signals, particularly 0 to 20 mA and 4 to 20 mA signals from transmitters, sensors, instrumentation and process equipment.

This module uses differential analogue inputs and supports 0 to 20 mA and 4 to 20 mA input ranges. It offers 16-bit converter resolution, with measurement resolution of 2 microamps for 0 to 20 mA and 1.6 microamps for 4 to 20 mA. Accuracy is listed as ±0.1% full scale range at 25°C and ±0.3% full scale range across -40°C to 75°C. These specifications make the module suitable for monitoring process values such as pressure, flow, level, temperature transmitters and other industrial analogue signals.

The 65M-3600-CT-T also includes internal loop power support, with 24 VDC loop supply and up to 200 mA per group. This can simplify wiring for suitable current loop applications. The module allows overload up to ±30 mA on inputs and uses a 250 ohm input impedance. Conversion time is 100 ms, with normal mode and common mode rejection performance listed for 60 Hz environments.

Diagnostics include internal loop power detection, input short-circuit detection and input wire-break detection in 4 to 20 mA mode. These features help improve fault visibility and reduce troubleshooting time in remote I/O and process monitoring systems. The module provides 3 kVDC isolation between signal and system, plus 1 kVDC group isolation.

The compatible terminal block is 65M-TB-3600-CT-T, sold separately. With conformal coating support, tool-free installation, hot-swap design and -40°C to 75°C operation, the 65M-3600-CT-T is a robust current input module for modular ioPAC 6500 deployments.
