Honeywell 900A01-0202 Universal Analog Input module in Stock

Overview

The Universal Analog Input module supports up to 8 user-configurable inputs on a per-point basis for thermocouple, RTD, resistance, V, mV, and mA. It offers point-to-point isolation and backplane isolation. Modules perform analog-to-digital conversion in synchronization with CPU control execution, eliminating data interchange latency. All analog input modules are processed in parallel, eliminating scan time increases as modules are added. The module has a green blinking status LED when it is being scanned and a red status LED when module diagnostics exist. It supports a user-selectable BURURNOUTN value on a per-channel basis. A warning signal is provided for thermocouple inputs to indicate maintenance is needed before a sensor failure, and a sensor failure signal is also provided.
