Brief Introduction to HONEYWELL 900TBK-0001 Terminal Base
The HONEYWELL 900TBK-0001 is a dedicated terminal base designed for Honeywell’s 900-series controllers, ensuring secure wiring and easy maintenance for industrial automation systems.
1. Product Description
The HONEYWELL 900TBK-0001 is an industrial-grade terminal base engineered to work with Honeywell’s 900-series temperature and process controllers (such as the 900A01-0202). It’s widely used in manufacturing plants, power stations, and process control facilities—anywhere secure, organized wiring is critical for control systems.
Its core role is to provide a stable mounting and wiring interface for controllers. Instead of connecting wires directly to the controller (which risks loose connections), technicians wire the sensor, power, and output cables to the 900TBK-0001 first. The controller then clips onto the base, creating a secure electrical and mechanical connection.
Built for industrial durability, it resists dust and mild vibration, and its clear terminal labeling makes wiring quick and error-free. If a controller needs replacement or maintenance, it can be easily unclipped from the base without rewiring—saving technicians hours of work and reducing downtime.
2. Technical Specifications

3. System Introduction
The 900TBK-0001 is a key part of Honeywell’s “900-Series Control System”—a modular lineup that includes controllers, terminal bases, sensors, and wiring accessories. This system is designed to simplify the installation and maintenance of industrial control circuits, especially for small to medium-sized automation setups.
Let’s use a temperature control system for a plastic molding machine as an example to see how it works:
-
Technicians mount the 900TBK-0001 on the 35 mm DIN rail in the control cabinet, alongside other terminal bases and components.
-
They wire the Pt100 temperature sensor (from the molding machine) to the “INPUT” terminals of the base, the 24 V DC power cable to the “POWER” terminals, and the heater control wire to the “OUTPUT” terminals.
-
The Honeywell 900A01-0202 temperature controller is clipped onto the 900TBK-0001, automatically making electrical contact with the terminals.
-
If the controller needs calibration later, it’s unclipped from the base without touching the wires—minimizing downtime for the molding machine.
This system is popular in industrial settings because it reduces wiring errors, speeds up installation, and simplifies maintenance—all critical factors for keeping production lines running smoothly.
