Half-height rear power termination card for 3500/15 low voltage DC front power supply, accepts 20~30VDC input, provides field wiring terminal for 3500 TSI rack redundant DC power system, tested surplus spare parts for turbomachinery monitoring

Product Overview

• PN: 3500/15 114M5335-01
• Brand: Bently Nevada (Baker Hughes)
• Series: 3500 Machinery Protection TSI System
• Type: Low Voltage DC PIM (Power Input Module, Rear Termination Card)

• Function: Dedicated rear wiring board paired with 3500/15 low voltage DC front power module. It accesses external 20~30VDC low-voltage direct current power from site power distribution cabinets, transmits power to the front power unit, and converts it into multi-group stable DC bus voltage to supply all monitoring, communication, relay and display modules inside the 3500 rack. Two pieces can be installed simultaneously to build 1+1 redundant power backup, ensuring the whole monitoring system runs without interruption.

Core Features

1. Standard low voltage DC input range: 20 ~ 30 VDC, widely applicable to 24VDC industrial control power supply scenes
2. Half-height structural dimension, perfectly match the two dedicated power slots on the left rear of all 3500/05 series racks, front and rear cards must be installed in one-to-one correspondence
3. Adopts anti-loose screw locking terminals, effectively prevent wire loosening in vibration-prone industrial environments
4. Built-in fuse, overvoltage, overcurrent and short-circuit protection circuit, automatically cut off abnormal input to protect rack backplane and front power supply

5. Support hot swap under redundant power configuration; replacing a single PIM card will not cause the entire rack to power off and stop working
