Product Description

Overview

The Honeywell 900R12-0101 rack provides a stable platform for HC900 Controller systems that require flexible modular expansion and dependable long-term performance. Each installation benefits from its rugged frame, which holds up to twelve I/O modules for diverse control tasks in demanding industrial environments. Moreover, the rack supports both 5 VDC and 24 VDC operation, allowing engineers to integrate mixed-voltage modules without redesigning existing control architecture. In addition, its wide temperature range makes the assembly suitable for facilities operating under harsh or fluctuating environmental conditions.
