MRV Components

As shown below, the minimum SMARTLINK

MRV system requires two Valve Actuators and one (DIN rail-mounted) Control

Interface. A total of four Valve Actuators can by supported by one Control Interface. In addition, several optional DIN rail-mounted

components are available to simplify electrical interfacing and commissioning. These optional components include:

a) Relay Input Interface – Provides the electrical interface between the 6 Control Interface inputs and the customer’s burner

management or flame safety device. This device is available in 120VAC, 230VAC, and 24VDC models.

b) Relay Output Interface – Provides the electrical interface between the 5 Control Interface outputs and the customer’s burner

management or flame safety device.

c) Network Interface – Provides a plug-type terminal connector for all SMARTLINK

MRV field devices.

d) User Display – Provides a 4-line x 20-character LCD display for system commissioning and maintenance.

e) Universal Power Supply – Provides regulated 24VDC power to all SMARTLINK

MRV system components.

These optional components can be ordered individually and wired by the customer. However, two SMARTLINK

MRV Interface

Panel assemblies are available with factory-wired components as follows:

(1) 24” x 20” Interface Panel: Includes factory-wired Input & Output Relay Interfaces, Network Interface, Supply, Control

Interface, User Display, and Terminal Block Assembly

(2) 20” x 16” Interface Panel: Includes factory-wired Input & Output Relay Interfaces, Network Interface, Supply, Control

Interface, and Terminal Block Assembly

The larger, 24” x 20” Interface Panel includes a User Display. Both Interface Panels provide a 4-Amp breaker and power switch as

well as a labeled terminal block for field wiring.

The Interface Panels can be specified with a windowed, NEMA 4X enclosure in painted steel, 304-stainless or 316-stainless.

When provided with a NEMA 4X enclosure, the complete package is Class I, Division 2, and ATEX and IEC Ex approved

and no purging equipment is required.

Because SMARTLINK

Valve Actuators communicate digitally to the Control Interface, an EIA Level 4 Cable with 2 twisted pair

and shield is required for these connections. Required cable may be purchased from MAXON. See the Electrical Installation

section for wiring specifications.
