1B30023H02 dedicated I/O termination base

1B30023H02 is a dedicated I/O termination base developed by Emerson for its Ovation Distributed Control System (DCS). It serves as a critical intermediate connection component between Ovation I/O modules and field wiring, providing stable signal transmission, power distribution, and physical protection—essential for ensuring reliable operation of the DCS I/O layer in harsh industrial environments. Below is its detailed information:

1. Core Technical Specifications

Parameter Category	Specific Details
Slot Configuration	1-slot design, exclusively matching single Ovation I/O modules (e.g., analog input modules like 1C31194G03, digital output modules like 1C31219G01). Ensures precise alignment with module pins for stable signal and power connection.
Electrical Parameters	- Rated Voltage: 24V DC (power supply for I/O modules) + 480V AC (optional, for field device power distribution in some scenarios).- Rated Current: 10A per slot (supports power demands of most Ovation I/O modules, including high-current digital output modules).- Wiring Interface: Screw terminal blocks (16–24 AWG wire compatibility), with anti-loosening design to prevent poor contact caused by industrial vibration.
Isolation & Protection	- Galvanic Isolation: Between field wiring terminals and module connection pins (≥500V AC, 1 minute), suppressing ground loops and electromagnetic interference (EMI) from field equipment (e.g., motors, inverters).- Overcurrent Protection: Built-in self-resetting fuses for power supply circuits, preventing module damage from short circuits or overloads.- Surge Protection: Optional transient voltage suppressor (TVS) components (for harsh EMI environments) to shield against voltage spikes.
