900A16-0103 Honeywell Analog Input High Level 16 Channel
900A16-0103 Honeywell Analog Input High Level 16 Channel
Technical Specifications:
Analog Input High Level, 16 Channel (900A16-0103)
The High-Level Analog Input module supports up to 16 user-configurable inputs on a per-point basis for voltage or current. It provides point-to-point isolation and back-plane isolation. The 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. A green blinking status LED on the module indicates when the module is being scanned, and a red status LED indicates when module or channel diagnostics exist.
