Selection must follow the complete part number and installed-system configuration. Before ordering, confirm required relay output and contact arrangement, logic programming and rack configuration, companion relay output module and approvals.
COMMON APPLICATIONS
Tell us the controller, communication network and installed panel details. That context helps prevent a visually similar but incompatible replacement.
BENTLY NEVADA MODEL CODE
Read the complete ordering code from left to right. Every group matters when matching an installed system or preparing a spare.
VERIFIED MODEL DATA
Technical values are compiled from official Bently Nevada product documentation for this exact article number. Always check the delivered unit nameplate and revision before installation.
Availability, condition, revision and exact installed-system compatibility are confirmed in writing before supply.
BUYER QUESTIONS
It is a 16-Channel Relay Control Module used for programmable relay outputs for alarms, trips and annunciation.
Confirm the full part number, then verify required relay output and contact arrangement, logic programming and rack configuration, companion relay output module and approvals.
Do not select by appearance alone. The monitor family, companion module or transducer, rack configuration, signal type and hardware revision must match the installed system.
Send the complete part number, quantity, required condition, destination and clear nameplate or rack-BOM photos.
FRONT AND REAR CARD COMBINATIONS
Use the complete ordering code to match the required rear I/O interface and certification. The front-card part number identifies the monitor or control module; the rear-card part number identifies the I/O, termination and signal arrangement.
