Product Description

CT-3268 Current Analog Input Module 8AI

8 channels analog input /0～20mA OR -20~0mA OR ±20mA /15bit Single-ended bipolar

1. The module supports 8-channel current signal acquisition.

2. The module can be configured for 0~20mA OR -20~0mA OR ±20mA current signal acquisition.

3. The module supports 2-wire (non-loop output, external power supply is required)

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

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

6. The module channel equips with TVS overvoltage protection.
