Tips on how to replace and setup to a NEW Barber-Colman MODEL 3504 CONTROLLER

Barber-Colman makes it simple and easy to upgrade your system by replacing your aging model 560 or 570 controller. The new Eurotherm controller model 3504 is the new replacement for the old Barber Colman 560 and 570 programmer.

WE KNOW YOUR 560 BECAUSE WE BUILT IT!

To upgrade to the new Barber-Colman controller follow these steps:

1- Locate the Barber-Colman 560 or 570 controller part number located on the side of the instrument case, there is also a copy of the part number on the top lip of the controller if you have already removed it from the case. If you look carefully at the rear terminal wiring of the Barber-Colman 560. It will most likely have: 3 incoming power wires, 2 thermocouple wires output wires that go to a motorized valve OR to a heat contactor maybe output wires that go to an alarm light maybe a few extra wires.

2- You can mount the 3504 controller in a new hole, make a cover plate that converts the larger 6 inch by 6 inch cut out to the newer 1/4 DIN cutout. Contact us about availability of a converter plate. Then, if you follow our easy to use wiring diagrams, reconnect your existing wires and you have a permanent installation.

We can also supply an adapter housing so the new 3504 slides right into the existing housing so you don’t need to touch any wires. This is great for rapid replacements of one or two instruments

If you are using the 560 digital interface, we can supply the traditional 560 or 570 protocol. Just reconnect the wires to the new 3504, set the address and baud rate and watch the communications take off. The 3504 can have a plug-in board installed (either now or later) that permits it to communicate using Modbus RTU. A factory developed Modbus RTU OPC server is available for OPC interfaces to visualization software.
