Bently Nevada ORBIT 60 SERIES Relay Modules

Description

Relay modules may be programed to actuate based on

alarm conditions defined in other modules.  Use standard

logic elements (True AND, Normal AND, OR and NOT) to

combine various alarms and statuses (e.g. OK statuses,

Bypass, Protection State, Inhibit, Attention, Protection Fault,

etc.) into relay activation conditions. Orbit Studio is used to

program the voting logic.

Relays can operate as a  system or group protection fault

relay, if programmed to do so, especially when the protection

fault relay on the SIM does not provide adequate granularity

of system health - typically for multiple machines in one system.

Pairs of relays within the module function as a single Double

Pole, Double-Throw relay when appropriately configured.

Both relay types are available for SIL system implementation.

See Orbit 60 SIL User Guide (134M0398) for additional details

and design considerations.

Electromechanical Relay (EMR)

This relay drives a load directly, or through, an interposing

relay. This module takes two slots. It features 8 Epoxy Sealed,

Single-Pole Double-Throw Electromechanical Relays. This

module supports an AC voltage range of 5-250 Vac for loads

of 100 mA to 4 A. The module also supports DC voltages and

loads of 5-30 Vdc at 4 A.

Solid State Relay (SSR)

This relay connects to an external system’s discrete input for

low current communication. It occupies a single slot and

features 8 Solid-State Relays. This module supports

secondary voltages from 1 Vdc up to 125 Vdc

and loads of 0.01 to 125 mA.
