Product Description

CT-3234 Current Analog Input Module 4AI

1. The module supports 4-channel current signal acquisition

2. The module can be configured for 0-20mA or 4-20mA current signal acquisition.

3. The module supports 2-wire (non-loop output, external power supply is required) or 4-wire current sensor input.

4. The internal bus of the module and field input adopts magnetic insulation.

5. The module input channel is connected to the field active analog signal current output sensor.

6. The module channel equips with TVS overvoltage protection.
