ADAM-6250 Industrial Digital I/O Module Features
Eight Digital Inputs For Field Device Monitoring
The ADAM-6250 provides eight digital input channels for monitoring switches, sensors, machine status signals, alarms, and dry or wet contact field devices.Seven Sink Type Digital Outputs For DC Load Control
Seven sink type outputs provide switching control for compatible 10 to 30 VDC field loads with a normal output current of up to 100 mA per channel.Configurable Dry And Wet Contact Signal Support
Digital inputs support dry contact and wet contact operation, selected through a switch. The module supports sink NPN and source PNP compatible input device types.Counter Frequency And Pulse Output Functions
The module supports 3 kHz counter input, 3 kHz frequency input, and 5 kHz pulse output functions. Counter data may be retained or discarded when power is removed to suit application requirements.Daisy Chain Ethernet Connectivity
Two 10/100Base TX Ethernet ports enable daisy chain network connections. Auto bypass protection maintains downstream Ethernet communication if a module unexpectedly loses power.Peer To Peer And Graphic Condition Logic Control
Peer to Peer communication supports direct I/O mapping between compatible modules, while Graphic Condition Logic enables user defined local automation rules. Only one of these functions can be enabled at a time.Built In Status Indication And Industrial Protection
LED indicators provide status for all eight digital inputs and seven digital outputs. The ADAM-6250 includes 2,500 VDC isolation, TVS and ESD protection, ±35 VDC overvoltage protection, and power reversal protection.
