ADAM-6266 Industrial Relay Output Module Features
Four Form C Relay Outputs For AC And DC Load Control
The ADAM-6266 provides four Form C relay outputs for remotely switching compatible industrial loads such as pumps, solenoids, contactors, alarms, lighting circuits, and valves.Four Digital Inputs For Equipment Status Monitoring
Four digital input channels monitor dry or wet contact signals from field devices. Switch selectable dry and wet contact operation supports use with sink NPN and source PNP compatible devices.High Capacity Relay Switching Performance
Each relay supports resistive loads up to 250 VAC at 5 A or 30 VDC at 5 A, with a maximum switching voltage of 400 VAC or 300 VDC and a maximum breakdown capacity of 1250 VA.Counter Frequency And Pulse Output Functions
Digital inputs support 3 kHz counter input and 3 kHz frequency input functions. The module also supports 5 kHz pulse output and configurable retention or discard of counter values following power loss.Daisy Chain Ethernet Connectivity
Dual Ethernet ports enable 10/100Base TX daisy chain network connections. Auto bypass protection helps preserve network communication with downstream modules when an individual module unexpectedly shuts down.Peer To Peer And Graphic Condition Logic Control
Peer to Peer communication enables direct I/O mapping between compatible modules, while Graphic Condition Logic supports user defined logic rules for local automation. Only one of these functions can be enabled at a time.Industrial Protection And Local Status Indication
The ADAM-6266 includes 2,500 VDC isolation, TVS and ESD protection, ±35 VDC overvoltage protection, and power reversal protection. Four relay LEDs and four digital input LEDs provide local channel status indication.
