Bently Nevada 136294-01 Isolated +4 to +20 mA I/O Module

Description

The Bently Nevada 136294-01 is an isolated +4 to +20 mA I/O module with internal terminations designed for processing machine-critical parameters in the 3500 Machinery Protection System. Installed in the rear slot of the 3500 rack directly behind the 3500/62 Process Variable Monitor main module, it accepts up to 6 channels of 4 to 20 mA DC input signals from field transmitters. The 136294-01 provides 500 Volts of galvanic isolation to protect system architecture against ground loops and signal interference while transferring conditioned parameter data to the main monitor board for alarm setpoint evaluation and machinery protection.

Features

• Accepts up to 6 channels of 4-20 mA DC input signals
• Provides 500 Volts isolation for signal lines
• Features internal termination block connections for direct field cable wiring
• Connects directly to the 3500/62 Process Variable Monitor main board via the 3500 backplane
• Low 50 Ohm input impedance for 4-20 mA current loops

Applications

• Machine parameter monitoring (pressures, flows, temperatures, and levels)
• Continuous machinery protection and condition monitoring systems
• Industrial process variable signal conditioning

Technical Specifications

Installation Guidelines

• Install the module in a full-height rear slot directly behind the 3500/62 Process Variable Monitor main module.
• Ensure proper field wiring connection directly to the internal termination headers.
• Maintain environmental operating temperatures between -30degC and +65degC.
