Product Snapshot

The 129133-01 is the 3500/01 System Monitor Module—the mandatory "heartbeat" of every Bently Nevada 3500 rack. It continuously supervises power-supply voltages, rack temperature, module presence, and user-relay states, then drives the System OK contacts of the 3500/32 Relay Module. Without this board, the rack cannot achieve API 670 or SIL 2 certification and will fail start-up self-test.

Key Features & Benefits

Mandatory for API 670 & SIL 2 - required in every 3500 rack
Triple-rail supervision - +5 V, +12 V, -12 V with ±1 % accuracy
On-board temperature sensor - alarm at 65 °C, shutdown at 75 °C
Module-reality check - confirms configured modules are physically present
System OK relay drive - energizes 3500/32 contacts within 1 s
Hot-swap - rack remains powered during replacement (≤ 30 s)
Wide environment - -30…+65 °C, 95 % RH non-condensing, 5 g vibration
Global approvals - CE, UL, ATEX Zone 2, IEC 61508 SIL 2, RoHS, REACH
