GE VMIVME-3230

• Thermocouple Support: Compatible with multiple thermocouple types (e.g., J, K, T, E) with automatic cold-junction compensation and linearization.
• Isolation: All input channels are filtered, isolated, and equipped with normal-mode overvoltage protection.
• Connectivity: Thermocouple connections via screw terminals directly linked to the front-panel P3 connector.
• Communication: Embedded serial communication interfaces (RS-232/RS-485) supporting Modbus RTU Slave, SNP Slave, and Serial I/O protocols.
• Backplane Compatibility: Dual backplane support (RX3i PCI and 90-30 serial) for integration into legacy systems.
• Program Blocks: Supports up to 512 program blocks with 32 Kbits of discrete I/O memory (%I/%Q).
• Real-Time Clock: Battery-backed RTC with a 5-year lifespan and daily drift of ≤2 seconds.

Functional Characteristics
