Remote IO
The TB20 distributed IO system, made by Helmholz, is a high quality, low cost IO system that can fit onto a wide variety of buses (PROFIBUS, PROFINET, CAN-bus, ModbusTCP, Ethernet IP, EtherCAT) and comes in a very small footprint.
JCOM Automation Inc. has been using these IO modules on our training equipment for over eight years. They have been shipped from one end of this great country to the other and back again many times. We have not had one failure in all that time. These are tough modules.
Please contact us and we can help you select the best IO module for your application and provide a quote.
