Satchwell retrofit solution is a direct replacement for Satchwell BAS2000, 2800, and Sigma rack-type controllers, including modules and CPUs for Satchwell 132 and 532 outstations. It allows you to retain your existing control panel wiring, sensors, actuators, and relay outputs, providing cost-effective and hassle-free upgrades. Using industry standard ModbusRTU communications from I/O boards to Tridium JACE, the system offers reliable technology that has proven to save 20-30% compared with replacements using other systems.

Modernise Your Satchwell Controls – Without the Cost or Disruption
The Satchwell Retrofit Solution gives you a fast, low‑risk way to modernise legacy Satchwell BAS2000, 2800 and Sigma rack‑type controllers, including Satchwell 132 and 532 outstations – without ripping out what already works.

By directly replacing the original CPUs and modules, you can retain your existing panel wiring, field devices, sensors, actuators, and relay outputs, dramatically reducing installation time, site disruption, and project cost. The result is a straightforward, drop‑in upgrade that keeps your building running while extending the life of your investment.

Using industry‑standard Modbus RTU communications between the I/O boards and a Tridium JACE, the solution delivers a secure, open, and future‑proof platform – free from proprietary lock‑in. This proven architecture not only improves reliability and maintainability but typically reduces upgrade costs by 20 – 30% compared to full system replacement with alternative solutions.
The benefits at a glance:

✅ Upgrade obsolete Satchwell systems without rewiring
✅ Minimise downtime, disruption, and risk
✅ Retain existing field devices and panels
✅ Open, non‑proprietary communications (Modbus RTU)
