Compatibility and Software Requirements
Ensure your system meets the following requirements for proper operation:

- Requires 3500 Data Display Software version 1.40 or later
When ordered with the multiple approvals option (-02), the module is certified to Zone 2 standards, including ATEX and North American zones. However, note that the 3500/33-01-00 149992-01 does not meet increased spacing requirements at higher voltages, so the voltage is limited. For CSA-only approvals (-01), the voltage is de-rated to 30 Vrms to comply with 61010-1 type test requirements. If used in functional safety (SIL) systems, the restricted voltage must be followed; higher voltages are not allowed.
Applications
The 3500/33-01-00 149992-01 is ideal for machinery protection systems, vibration monitoring, and critical asset protection in industries such as power generation, oil and gas, and manufacturing. Its relay outputs can drive alarm annunciators, shutdown systems, or PLC inputs, providing a robust interface between the monitoring system and plant control.
Maintenance and Reliability
With a relay contact life of 10,000 cycles, the 3500/33-01-00 149992-01 offers long-term reliability. The epoxy-sealed relays protect against environmental contaminants, while the built-in arc suppressor (250 Vrms) extends contact life. Regular inspection of relay operation and system functionality is recommended to ensure continuous protection.
