Quick Detail

Description

The 3500/33 16-Channel Relay Module is a full-height automation output module for Bently Nevada™ 3500 racks, delivering 16 independent SPDT relay channels in a single rear slot. The 3500/33 16-Channel Relay Module enables large-scale alarm routing and equipment trip control within turbine, compressor, and generator protection systems. Each output of the 3500/33 16-Channel Relay Module executes programmable AND/OR voting logic using Alert, Danger, Not-OK, or measured variables from any rack monitor channel.

The 3500/33 16-Channel Relay Module consumes 5.8 W typical while driving up to 5 A per relay. AC switching capacity reaches 5 A at 250 Vac with 1200 VA maximum power, allowing the 3500/33 16-Channel Relay Module to control high-load annunciators, solenoids, and shutdown circuits. DC ratings include 70 W at 24 Vdc, 10 W at 48 Vdc, 9 W at 60 Vdc, and 125 Vdc maximum. Four groups of four channels can be configured as Normally De-energized or Normally Energized, enabling segmented alarm and trip design. Epoxy-sealed relays with arc suppressors rated at 250 Vrms support repeated alarm switching in automated protection cabinets.

Applications

Drive 16 Shutdown Solenoids at 5 A 250 Vac Load

The 3500/33 16-Channel Relay Module switches up to 5 A at 250 Vac with 1200 VA maximum AC power. This capacity allows the 3500/33 16-Channel Relay Module to directly control multiple turbine or compressor shutdown solenoids without adding external interposing relays. With 16 SPDT outputs in one slot, the 3500/33 16-Channel Relay Module supports high-density trip distribution inside automation cabinets.

Combine Multi-Channel Alarm Inputs Using AND OR Voting

Each relay in the 3500/33 16-Channel Relay Module executes programmable AND/OR logic using Alert, Danger, Not-OK, or measured variables from any rack channel. The 3500/33 16-Channel Relay Module enables logic such as 2-out-of-3 vibration trips or combined temperature and speed conditions before energizing a relay, reducing unnecessary shutdown events in rotating equipment systems.

Send Hardwired Alarm Outputs to PLC or DCS at 24 Vdc 70 W

The 3500/33 16-Channel Relay Module supports 70 W at 24 Vdc, 10 W at 48 Vdc, and 9 W at 60 Vdc, with 125 Vdc maximum. These DC ratings allow the 3500/33 16-Channel Relay Module to transmit alarm and trip signals to PLC or DCS digital inputs in automated process lines.

Specifications

Competitive Advantage

Deliver 1200 VA Switching Capacity in One Rear Slot

With 1200 VA AC switching power and 5 A current per relay, the 3500/33 16-Channel Relay Module reduces panel space and wiring compared to multiple smaller relay modules.

Provide 16 Independent SPDT Outputs with 5.8 W Rack Load

The 3500/33 16-Channel Relay Module consumes 5.8 W typical while controlling 16 channels, enabling higher channel density per rack without exceeding system power limits.

Support 10000 Relay Operations for Repeated Alarm Events

Epoxy-sealed relays rated for 10000 cycles allow the 3500/33 16-Channel Relay Module to handle frequent automated alarm actuation in continuous industrial processes.

Integrate Arc Suppressors Rated at 250 Vrms

Built-in 250 Vrms arc suppression in the 3500/33 16-Channel Relay Module protects contacts during high-voltage switching, extending service intervals in turbine and compressor protection systems.
