Complete Wireless Control Network

Built to protect. Designed to scale.

FieldLink connects remote inputs and equipment into one wireless network for monitoring, alarms, control events, and coordinated shutdowns from the Master or any Node.

!
Any Master or Node input can initiate a network shutdown

High water, pressure fault, power loss, emergency stop, or any configured input can stop assigned equipment across the network.

Optional Connectivity

Turn on cellular. Extend visibility.

Keep the core FieldLink network local, then add SMS alarms and cloud monitoring when your site needs them.

Cellular SMS Alarms

Enable cellular connectivity with the onboard DIP switch to send SMS notifications for alarms, shutdowns, Node offline events, and system restores.

DIP switch enabled
FieldLink Cloud Dashboard

Optionally monitor all sites from one dashboard, including Master status, Node health, inputs, outputs, alarms, signal strength, and event history.

Multi-site visibility

✓Core monitoring, control, and shutdown functions continue locally even if cellular or cloud service is unavailable.

How a shutdown works

1
Input detectedA configured input at the Master or any Node changes state.
2
Master validatesAlarm delay and shutdown logic are applied.
3
Command sentThe Master sends a command to assigned Nodes.
4
Outputs activateNode relay outputs change state.
5
Equipment stopsPumps stop and alarms or notifications are generated.

✓The shutdown network operates locally and does not depend on cellular service or the cloud.

Heartbeat MonitoringContinuous supervision of the Master and every Node.
Alarm & NotificationsOptional SMS alarms with cellular enabled, plus dashboard and SCADA notifications.
Latching & Fail-SafeLatch on alarm and optional fail-safe on communications loss.
Long-Range Reliability10+ mile capability with repeater support when required.
Scales With YouSupports up to 8 Nodes per wireless network.
Multi-Site Cloud DashboardOptionally monitor every FieldLink site from one centralized dashboard.

Traditional radios do not know they have failed

Know immediately when something goes wrong.

FieldLink continuously supervises every Node. When communication stops, the Master detects it, records the event, sends configured notifications, and can initiate a fail-safe response.

Traditional Shutdown Radio

Silent failure

The radios may stop communicating, but there is no heartbeat supervision to tell the operator.

Master RadioAppears normal
Remote RadioOffline or unpowered
!
Nobody knows

The failure may remain hidden until a shutdown is needed or an operator visits the site.

  • No heartbeat supervision
  • No communication-loss alarm
  • Manual testing and site visits
  • Failure discovered after the fact
FieldLink

Supervised network

The Master expects continuous heartbeats and reacts when a Node stops reporting.

1
Heartbeat activeMaster continuously verifies Node communication.
2
Node goes offlinePower loss, radio failure, or damaged equipment stops reporting.
3
Master detects lossThe missed heartbeat becomes a supervised network event.
4
Operator notifiedOptional SMS and cloud alerts identify the affected site and Node.
5
Fail-safe responseConfigured alarms, latching, or shutdown actions are applied.
Example response

From communication loss to operator awareness

1
0 secNode stops reporting

Communication or power is lost.

2
HeartbeatMaster identifies the missed check-in

The network event is created locally.

3
AlertSMS and dashboard update

Configured recipients receive the event.

4
ActionOptional fail-safe or shutdown

Assigned equipment moves to its configured safe state.

FieldLink does not wait for an operator to discover a silent radio failure.

Optional Cloud Monitoring

Your network never sleeps.

Every heartbeat. Every alarm. Every relay. Every site.

One dashboard gives operations, maintenance, and management instant visibility into every Master, every Node, every alarm, and every relay across every site.

FieldLink industrial wireless shutdown controller
Configured RoleMaster

Set the role, power the controller, and place it into service—no separate hardware model required.

Why universal hardware matters

One part number simplifies the entire lifecycle.

Installers no longer need separate Master, Node, and Repeater inventory. Any spare controller can replace any field unit.

One part number to stock

Simplifies purchasing, warehousing, and spare-parts planning.

Any unit can replace any unit

Carry one universal spare for every supported role.

Faster field replacement

Swap the controller, set the DIP role, and return to service.

Easy network expansion

Add Nodes or Repeater coverage without ordering a different model.

Lower inventory cost

Fewer unique devices and fewer dedicated spare parts.

Maximum uptime

Simpler service and faster replacement reduce operational downtime.
