Product Brief Introduction
The 20836416 is a 16-channel relay output module for Bently Nevada machinery monitoring and protection systems. It provides isolated relay outputs for alarm annunciation, equipment shutdown and control system interfacing, with programmable logic and fault-safe operation.
Technical Specifications
Number of outputs: 16 individually isolated relays. Contact type: Form C SPDT. Contact rating: 2A @ 250V AC resistive. Isolation: 2500V AC contact-to-coil, channel-to-channel. Power supply: 24V DC. Power dissipation: 6W. Operating temperature range: -20°C to +65°C.
Functional Features
Sixteen independent relay outputs support flexible alarm and control logic. Galvanic isolation separates control circuits from field circuits. Programmable contact logic supports normally energized or de-energized fail-safe operation. Front panel status indicators show output state. It supports test and inhibit functions for system testing.
Application Scenarios
It provides alarm output and protection interfaces for rotating machinery monitoring systems, turbine protection systems, compressor control panels, equipment shutdown systems, and annunciator panels.
Performance Parameters
Contact rating: 2A @ 250V AC resistive. Electrical life: 100,000 operations at rated load. Operate time: <10ms. Release time: <8ms. Operating temperature range: -20°C to +65°C.
Material Composition
Housing: UL 94 V-0 flame-retardant plastic. Relay contacts: silver alloy. PCB: FR-4 glass epoxy. Terminals: tin-plated copper alloy.
Structural Characteristics
It adopts standard rack-mount card form factor with front panel channel status LEDs, rear terminal block output connections, backplane communication connector, and card guide mounting.
Working Principle
It receives alarm and status commands from the monitoring system controller, energizes or de-energizes corresponding relay coils, and opens or closes the isolated contact points to switch external circuits, annunciate alarms, or initiate protection actions.
Installation Requirements
Install in designated slot of the monitoring system rack. Wire output circuits per contact rating specifications. Install surge suppression for inductive loads. Group circuits by voltage rating. Ensure reliable protective grounding.
