Key Characteristics
Electrical & Switch Ratings
Minimum Switched Load: Requires a minimum of 100 mA @ 5 Vdc to ensure proper mechanical contact wetting on standard silver contacts.
Built-In Protection & Status Tracking
Individual Channel LEDs: The front panel features a CH ALARM LED for each of the 16 relays, giving operators immediate visual indication of which specific output is currently energized or tripped.
Group Configuration: Relays are divided into four groups of four channels, which can be configured via board switches for Normally De-energized or Normally Energized states.

Common Questions Answered
Q: How does the "Alarm Drive Logic" of the 3500/33 149986-01+149992-01 work?
A: Each relay features independent Alarm Drive Logic, allowing the use of AND and OR logic gates. It can combine Alert/Danger statuses, Not-OK statuses, or individual measured variables from any monitor channel in the rack for voting determination.
Q: Does the 3500/33 149986-01+149992-01 support voting logic?
A: Yes. Each channel can be programmed for voting logic (e.g., 1-out-of-2, 2-out-of-2) to reduce false trips or missed trips.
Q: What is the typical response time of the 3500/33 149986-01+149992-01 module?
A: The response time is typically less than 10 milliseconds (ms), enabling fast equipment protection.
Q: What types of products do you specialize in?
A: We specialize in industrial automation components, including PLC modules, sensors, servo drives, and discontinued parts from major brands like Siemens, Allen-Bradley, and Bently Nevada.
