Product Overview
The HONEYWELL 621-6550 is a 16-channel analog input module for the Honeywell IPC 620 PLC system. It captures precise analog signals from field instruments, including transmitters, sensors, and controllers. The 621-6550 is suitable for industrial automation applications that monitor temperature, pressure, flow, and level.
Engineered for reliability, this module features channel-to-channel and channel-to-system isolation, which protects signals from interference. Integrated LED indicators display channel and module status, while built-in diagnostics ensure immediate fault detection. The compact module measures approximately 10" x 8" x 2" (25 cm x 20 cm x 5 cm) and weighs 1.4 lbs, fitting securely into IPC 620 racks with tool-less keyed connectors.
With CE compliance and adherence to industrial EMC standards, the Honeywell 621-6550 guarantees safe and reliable operation under demanding factory conditions.
