Emerson 1B30023H02 Ovation Terminal Module

Configured for field wiring termination in Ovation Distributed Control System racks, the Emerson 1B30023H02 (1B30023H02 Terminal Module) provides direct physical/electrical execution.

Hardware Specifications

4-20 mA HART Loop Protocol & Channel-to-Channel Isolation

The Emerson 1B30023H02 routes analog and discrete field signals directly to corresponding active Ovation I/O processing modules. When interfacing with 4-20 mA HART loop protocol field devices, the passive terminal architecture preserves signal integrity by preventing ground loops and cross-channel noise propagation. Solid field screw terminals maintain tight contact pressure to prevent impedance spikes during low-level voltage or milliamp signal execution, while dedicated shielding paths ensure channel-to-channel isolation parameters remain intact across high-density control cabinets.

Frequently Asked Questions

Q: Does the 1B30023H02 terminal module require an active power supply input to operate?

A: No, the 1B30023H02 operates as a passive field termination base. It provides physical screw terminal termination points and signal routing to active Ovation I/O processing cards via pre-engineered interconnect cables without drawing power from the system backplane.

Q: Can maintenance personnel disconnect field wiring cables from the module without disturbing adjacent I/O processing cards?

A: Yes, field wiring terminates directly at the screw terminals on the 1B30023H02 module. You can disconnect or swap the connected I/O processing card via its interface cable without removing field signal conductors from the terminal block assembly.

Field Installation Guidelines

Mount the 1B30023H02 module securely onto the cabinet DIN rail within the designated Ovation enclosure slot. Verify that the mounting clip fully seats to prevent lateral movement during cabinet vibration. Prior to attaching field wiring, strip insulation to the specified length and torque each screw terminal according to standard industrial panel wiring specifications to avoid wire shearing or loose contacts.

Route incoming field instrument cables through cable troughs, separating low-level analog wiring from high-voltage AC conductors. Connect wire shields strictly at the designated ground bus to suppress electromagnetic interference. Before powering up the main Ovation I/O processing modules, verify keying configurations and ensure the interconnect cable locks firmly onto the multi-pin header.
