The Honeywell 900RTA-L001 Remote Terminal Panel organizes and protects field wiring for analog input modules. This specialized RTP efficiently interfaces various two-wire transmitters and resistance temperature detectors (RTDs) with your control system. Consequently, it significantly simplifies installation, maintenance, and troubleshooting processes.
Core Wiring Management and Safety Features
This panel features switch-selectable shunt resistors for flexible current loop configurations. Moreover, its common power supply terminals include individual 80 mA time-lag fuses for each transmitter circuit. Therefore, you can safely power multiple field devices while providing essential overcurrent protection. A master power switch also disconnects all transmitters for safe module maintenance.
