Technical Analysis of Bently Nevada 3500/61 Non-isolated I/O Module (133819-02)
1. Core functions
Module type: non-isolated digital input/output module
Channel configuration:
8 digital inputs: dry contact or wet contact (24-48V DC)
8 digital outputs: relay contact (2A @ 30V DC)
System integration: specially designed for Bently Nevada 3500 mechanical protection system
Typical application scenarios
Emergency stop circuit: connect the safety switch to the 3500 system.
Valve control: drive solenoid valve/indicator light.
Condition monitoring: receiving proximity switch/flowmeter signals.
Security and authentication
International standards:
API 670 (mechanical protection)
IEC 61010-1 (Electrical Safety)
Explosion-proof option: ATEX certified version can be configured (suffix is required)
Operation warning
Non-isolated risks:
Input/output sides need to share the same grounding reference point to avoid misoperation caused by ground potential difference.
Load limit:
The relay output shall not directly drive the inductive load (arc extinguishing circuit shall be added).
