 ABB DI814 3BUR001454R1 Digital Input Module The input voltage range is 18 to 30 volt dc and the input current source is 6 mA at 24 V. The inputs are divided into two individually isolated groups with eight channels and one voltage supervision input in each group. Every input channel consists of current limiting components, EMC protection components, input state indication LED and optical isolation barrier. The process voltage supervision input give channel error signals if the voltage disappears. The error signal can be read through the ModuleBus. The ABB DI814 is part of the ABB AC500 PLC programmable logic controller family. The DI814 module typically provides 16 digital inputs. It can be used to interact with a variety of field devices in an automation system.It has optical isolation between the input channels and the processing system. This helps protect the system from voltage spikes or surges on the input side.Detailed data: Input voltage range, "0" -30 .. 5 V Input voltage range, "1" 15 .. 30 V Input impedance 3.5 kΩ Isolation Grouped with ground isolation, 2 groups of 8 channels Filter time (digital, selectable) 2, 4, 8, 16 ms Current limitation Sensor power can be current limited by MTU Maximum field cable length 600 m (656 yards) Rated insulation voltage 50 V Dielectric test voltage 500 V AC Power dissipation Typical 1.8 W Current consumption +5 V module bus 50 mA Current consumption +24 V module bus 0 Current consumption +24 V external 0Frequently asked questions about the product are as follows: -What is the ABB DI814? The ABB DI814 is a digital input module that is used to interface digital field signals (such as switches, sensors, or other binary inputs) with a PLC. The module has 16 channels, each of which is capable of receiving signals from a digital device, which the PLC can then process for control or monitoring. -How many digital inputs does the DI814 module support? The DI814 module supports 16 digital inputs, which means it can read signals from up to 16 different digital devices. -4. Does the DI814 module provide input isolation? The DI814 module has optical isolation between the inputs and the internal circuitry of the PLC. This helps protect the PLC from voltage spikes and electrical noise that may occur on the input side.
