Opto 22 I/O modules for temperature control applications
These three groov Epic I/O modules meet precise requirements for temperature control applications. They include designs for mixed signal types, signal isolation and channel density. GRV-IDCSW-12 has discrete input, 12 channels and dc contact switch status; monitors the open/closed status of dry contact switches; and provides the necessary excitation voltage to power the circuit. GRV-IVI-12 has 12 isolated channels, each configurable to one of eight ranges from ±1.25 to ±160 V. It eliminates the need to segregate I/O signals over multiple modules. GRV-IRTD-8 with analog input, eight channels and temperature/RTD or resistor increases options for accuracy and I/O density in temperature applications.
