Bently Nevada 125720-02 4-Channel Relay Output Module

Hazardous-area and functional-safety output spare for the 3500/32M relay family

Product Description

The Bently Nevada 125720-02 is the manufacturer-listed spare 4-Channel Relay Output Module for hazardous-area systems and functional-safety systems in the 3500/32M relay family. It is the field-output portion of the relay assembly, not the 149986-02 Relay Control Module and not a complete front-and-rear module set.

For the Bently Nevada 125720-02, the project voltage class is a decisive selection boundary. Bently Nevada limits the relay contacts used in hazardous-area or functional-safety service to 30 Vdc or 30 Vac maximum; higher contact voltages shown for standard systems do not apply to this spare in those applications.

Features and Functions

Safety-system spare identity
Official ordering identifies this output module specifically for hazardous-area and functional-safety systems.
Four field relay channels
The 3500/32M architecture provides four independently programmed SPDT relay outputs.
Selectable normal state
Each relay channel can be switch-selected for normally energized or normally de-energized operation.

Technical Information

Manufacturer Bently Nevada
Part number 125720-02
Product family 3500/32M 4-Channel Relay Module
Product type Spare 4-Channel Relay Output Module
Intended system class Hazardous-area and functional-safety systems
Relay channels 4
Relay contact form Single-pole, double-throw (SPDT)
Channel normal state Switch-selectable: normally energized or normally de-energized
Restricted maximum switched voltage 30 Vdc or 30 Vac in hazardous-area / functional-safety service
Maximum switched current 2 A, resistive load, within the restricted voltage class
Rack position One full-height rear slot for the I/O/output module
Operating temperature -30 to +65 degrees C
Storage temperature -40 to +85 degrees C
Humidity 95%, non-condensing
Selection risk: do not apply standard-system voltage ratings

125720-02 is the output spare listed for hazardous-area and functional-safety systems. In those uses, the official maximum is 30 Vdc or 30 Vac; applying the higher standard-system relay ratings would conflict with the documented certification and safety restrictions.

Frequently Asked Questions

Does ordering 125720-02 provide the complete 3500/32M relay assembly?
No. It is the rear four-channel Relay Output Module; the corresponding front Relay Control Module and rack configuration are separate parts of the channel.
How should the normal relay state be prepared when 125720-02 is commissioned?
Set each channel for the approved normally energized or normally de-energized behavior, then prove the normal and alarm states against the cause-and-effect design.
What should be recorded before field conductors are moved to 125720-02?
Record terminal positions, contact use, load voltage and current, front control-module identity, and relay logic. Label each conductor before disconnection.
Where should troubleshooting begin when a relay connected through 125720-02 does not change state?
Check the front module OK and communication indications, channel alarm state, and Alarm Drive Logic before testing the field load. A missing relay command cannot be corrected by replacing the rear output module.
What must be demonstrated before 125720-02 is returned to an operating circuit?
Verify the rear-slot pairing and terminal map, then test the intended energized, de-energized, and alarm behavior using the approved site procedure.
What information should purchasing include with a request for 125720-02?
Provide the front control-module number, service classification, relay-load details, required component scope, quantity, destination, and clear label photographs.
