Q1: What is the primary function of the 3500/53 133388-01?
It is an electronic overspeed detection module used to monitor rotating machinery speed. When the speed exceeds a pre-set Danger/Overspeed threshold, it directly triggers relay outputs to shut down the equipment and prevent catastrophic mechanical failure.
Q2: Does the 3500/53 133388-01 have multiple input channels?
The module itself has one input channel. For redundancy and to meet API 670 requirements, multiple 3500/53 modules can be installed in adjacent slots and configured as a 2-out-of-2 or 2-out-of-3 (recommended) voting system.
Q3: What sensors are compatible with this module?
It accepts signals from Bently Nevada proximity probes (3300 and 7200 series Proximitor®) and magnetic pickups, with an input voltage range of +10.0 V to -24.0 V.
Q4: What are the key configuration requirements for this module?
The 3500/53 requires redundant power supplies in the rack . Additionally, the 3500/20 Rack Interface Module must have firmware Revision G or later, and the configuration software must meet specific version requirements.
Q5: What outputs does the module provide for alarm and protection?
The 133388-01 provides four SPDT alarm relay outputs (with a 5 A rating) for direct trip circuit connection and a 4-20 mA recorder output proportional to speed for monitoring purposes.
