Brief Introduction to HONEYWELL 900CS10-00 Compact Process Controller
The HONEYWELL 900CS10-00 solves this problem: it’s a compact, high-performance process controller that handles temperature, pressure, and level control without taking up extra space, making it a go-to for space-constrained automation setups.
1. Product Description
The HONEYWELL 900CS10-00 is an industrial-grade compact process controller engineered to monitor and regulate key process parameters, with a focus on temperature and pressure. It’s widely used in small-scale manufacturing, laboratory equipment, portable industrial tools, and tight-space control systems—such as mini food ovens, small water pumps, or desktop test rigs.
Its biggest advantage is its ultra-compact design: it fits into 22mm-wide panel cutouts, which is half the space of standard controllers. Despite its size, it doesn’t sacrifice functionality—it works with common sensors (like thermocouples or pressure transducers) and adjusts output devices (heaters, small valves) to keep parameters stable. For example, in a portable beer brewing kit, it can monitor the fermentation temperature and turn a small heater on/off to maintain the ideal 20°C.
Built for both lab and field use, it resists dust and minor impacts. Its simplified interface—with a small but clear display and intuitive buttons—lets technicians set values quickly, even in busy workspaces. It also pairs with Honeywell’s mini terminal blocks for easy wiring, perfect for equipment where every millimeter counts.

3. System Introduction
The 900CS10-00 is part of Honeywell’s “Compact Control System”—a lineup designed for small-scale automation, including mini controllers, micro sensors, and compact terminal blocks. This system focuses on space efficiency and easy integration, perfect for applications where standard-sized control components are too bulky.
Let’s use a small plastic injection molding machine as an example to see how it works:
-
A K-type thermocouple in the machine’s heating barrel measures the temperature (e.g., 180°C) and sends a signal to the 900CS10-00.
-
The controller compares 180°C to the setpoint (e.g., 200°C) and activates its relay output.
-
The relay turns on the barrel’s small heater. When the thermocouple detects 200°C, the controller shuts the heater off.
-
The controller uses basic PID logic to avoid temperature spikes—keeping the barrel steady at 200°C for consistent plastic melting.
For multi-device setups, multiple 900CS10-00 controllers can connect to a small Honeywell HMI (like the TK-PX100) for centralized monitoring. This system is popular because it’s affordable, easy to install, and turns small equipment into automated systems without space constraints.
