The TRUNKGUARDTM High Availability Fieldbus Power Conditioner (TPS400) provides modular, isolated and fieldbus-conditioned power to FOUNDATION fieldbusTM segments. It is designed for use with MooreHawke TRUNKGUARD Series 200 and Series 300 Device Couplers, as well as any other manufacturer's non-intrinsically-safe Device Couplers. The TPS400 supplies conditioned power to up to four fieldbus segments. Each TPS DIN Carrier has built-in connectors for two DC supplies (19.2-32V). On-board surge protection per segment is optional.
Each Fieldbus Segment Power Conditioner delivers up to 500mA of fully isolated and fieldbus-conditioned power per segment, fully compliant with FF831-1 and FF-registered. Fieldbus Segment Power Conditioners are used in redundant pairs, and are fully load-sharing and hot-swappable (can be removed and replaced from the Carrier under load without affecting segment operation).
General Purpose and Hazardous Area Installation
Installed in a safe area, the TPS400 can power both general purpose devices and hazardous area devices with approved fieldbus Device Couplers. The TPS400 is also suitable for Zone 2 / Division 2 mounting (consult the factory for the status of hazardous area agency approvals).
