Specific Application

• Centralized Machinery Monitoring Power: Providing continuous, voltage-regulated electrical power to drive up to 12 individual 3300 monitors and their paired proximity transducers.
• Hazardous Area Condition Tracking: Delivering reliable safety system operation in industrial zones requiring rigorous CSA Class I, Division 2 certification parameters.
• Industrial Line Filtering Protection: Suppressing incoming electrical line spikes and raw terminal cross-talk across power distribution circuits using a standard built-in noise filter.

System Compatibility

• Rack Mounting Slots: Installs strictly into the left-most slot (position 1) of any standard 3300 monitoring chassis.
• Chassis Capacity: Powers up to 12 monitors and their associated field sensors inside a single rack frame assembly.
• Internal Transducer Output: Distributes user-programmable -24 Vdc or -18 Vdc supply outputs directly via the integrated backplane interfaces.

Substitute Configuration & Technical Differences

• Alternative Suffix Version: ac Power Supply with Safety Barriers (Model: 3300/12-01-22-01).
• Key Differences:

• Power Input Module: The 3300/12-01-20-01 includes a standard power input module (PIM) layout, whereas the 3300/12-01-22-01 is equipped with internal safety barriers.
• Explosion Protection Integration: Standard PIM versions rely on external galvanic barrier hardware components for intrinsically safe field line setups, while internal safety barrier modules contain localized isolation hardware directly on the rear connection circuit footprint.

Installation & Troubleshooting FAQ

Q1: How do I physically modify the 3300/12 module input power configuration from 115 Vac to 220 Vac operation?
A: The base voltage range selection is field-changeable. You must physically change a soldered jumper position located on the primary circuit footprint board and replace the external line fuse with a matching lower-amperage rating component.

Q2: What is the correct replacement fuse size specification for this specific 3300/12-01-20-01 layout?
A: Because this suffix configuration is set for 95 to 125 Vac operation, you must use a 250V, 1.5 Amp slow-blow fuse component (Part Number 01701500) to ensure proper equipment overcurrent protection.

Q3: Why does the system description mention that a second power supply is never required inside the same rack?
A: The 3300/12 assembly is engineered with enough current overhead rating to power a maximum full-capacity load configuration of 12 distinct machine monitors alongside all their interconnected field proximity sensors simultaneously.

Q4: The machinery safety monitoring system has dropped dead, and all channels are dark. Where should I check first?
A: Isolate primary power inputs and extract the supply from position one to examine the physical fuse integrity. If an accidental surge occurred, the front or input module slow-blow fuse will open to isolate vital internal rack circuitry from damage.

Q5: How can I integrate an external alarm or warning light to signal a complete loss of primary plant power?
A: Wire your external industrial indicator loop directly to the on-board OK Relay terminal connections located at the Power Supply Input Module at the rear of the unit. The dry contacts use a single-pole double-throw (SPDT) layout that defaults to an open state if power drops out.
