Porter Model CM-400 is a high performance microprocessor based 4-channel power supply/ control module designed for use with Porter Mass Flow Meters and Controllers. An 8-line, backlit LCD display provides selectable data on the status of the 4 channels simultaneously; low noise, thermal overload protected +15 Vdc device power is provided on each channel.The CM-400 accepts user selectable current or voltage input signals and supplies a selectable setpoint signal for each channel.
|
In addition to the analog I/O, a digital communication port is included for computer/PLC interface. A programmable multichannel blend control and totalizer with batch function allows the CM-400 to precisely interact with Porter MFCs in a versatile and functional gas management system.
