VC-6000 Monitoring System

Monitoring Module – SM-610-A05
User-Defined: up to 2 x Vibration inputs, up to 2 x Phase Reference/Speed; up to 10 x Process signals
(resp. Air-Gap Measurements); up to 9 x Binary Inputs with 6 Relay outputs

The VC-6000 Monitoring System hardware is used for both stand-alone safety monitoring and condition
monitoring using the Compass 6000 monitoring software modules and database. The VC-6000 offers various
standard monitoring modules, power supply modules and communication modules. This Product Specification
describes the SM-610-A05.

Applications
The SM-610 series of VC-6000 Monitoring Modules
are designed to provide protective monitoring of
various types of industrial machines. The SM-610-
A05 is specifically designed as a “user-defined”
monitoring module, where there are a number of
selectable differential inputs and outputs. This is
useful for monitoring machines with special
applications. The second purpose of the SM-610-A05
is offering a free-configurable voting logic. Using the
various input channels allowing logic combinations
over different SM-610-xxx module, even in different
racks.

User Definable Measurement Channel Inputs (maximum subject to overall input allocation, with trip-multiply).

Figure 1. Phase/speed reference sensor input (up to 2 channels). Channel 1B can be designated as a master
speed/phase reference channel for distribution to other SM-610-xxx modules in up to 4 racks. Or the trigger
signal can be received from another SM-610-xxx module (Slave Trigger). If no speed signal is needed the
channels can be configured for vibration measurements.

Figure 2: 9 x binary input channels that go directly into the relay selector with a free configurable voting logic.
All binary inputs can be used for Trip Multiply signals (Logic operations are possible).
