Model: 57C409

The 2-channel analog input module is used to input analog signals to the local rack in the DCS 5000/AutoMax system. This module

Contains two channels that can be converted every 500 microseconds. Each channel offers 12-bit conversion plus signs, 100% overrange, and user-programmable filters and converters. The two input channels have an isolated common channel. Module inputs can be earth 1 V +5 V, Earth 10 V or 4-20 MA. The module can be configured to interrupt on each conversion.

Typically, the module is used to read analog voltage potentiometers, tachometers, drive control systems, and process control systems.

57C409 analog input module is a device that collects analog signals from remote field to computer, which uses RS-485 bus as a data communication line to provide analog to 485 function, which can simultaneously input analog data to the module and transmit it to the computer through RS-485 bus.

57C409 analog input module supports a variety of acquisition ranges, all kinds of configuration software docking, its communication protocol using MODBUSRTU protocol, and industrial field data acquisition to achieve a unified docking, programming is also very convenient. Analog input module is usually used to solve the PLC, motion controller analog input and other problems, such as current detection, voltage detection, temperature detection.
