The design and construction of the Automate I/O Modules is a direct response to PLC users who have found that many currently available I/O systems are components do not stand up to industrial service. Industrial applications hold many hazards for electronic devices, such as high temperatures, high humidity, high current loading (output circuits), electrical noise, and vibration. Outputs rats 2 amps at 60 degrees Celsius. Voltage levels for the 45C63 are 24 VDC. Each output circuit is electrically isolated and each output module is built to endure an inrush of 20 amps for 0.1 second.
