The difference is that the 3-wire device has a supply source (+), supply common (-) and signal (output). Compact PLC: Compact PLC type has inbuilt limited and fixed hardware modules. Although this method is more expensive than remote I/O (where the remote racks lack their own dedicated processors), it provides the capability of stand-alone control in the event the network connection between PLC processors becomes severed. How to choose between PLC and DCS Systems ? In a PLC system, the input/output modules are connected to the input/output devices that send and receive electrical signals throughout a process. In such cas…. Notice that the wiring of this figure shows lamp LT1 as only lighting when OUTPUT 1 is turned ON. LT2 is also lit when OUTPUT 3 is turned OFF. This is a typical situation since there may be occasions when devices connected to the output unit operate at different voltages. Addressable modules can be independently configured via a fire control panel for status or alarm messages. PLC controller output. In the PLC programming, Input modules are represented by the 'I' or 'X' and DVP06XA-S is able to receive 4 points of analog input signals (voltage or current) and convert them into 12-bit digital signals. If the PLC lost power lamp LT2 would light and provide the operator with an indication that the PLC had a problem. So, compact PLC is called as 'fixed PLC'. The term I/O refers to Input/Output. Every drive that does not belong to a simulated axis must be associated with a set value output module. A transistor output unit providing three open collector outputs is shown in Figure below.

PLC Inputs and Outputs provides an overview of the main types of input/output modules and input/output devices, their primary functions, and their roles in a PLC process. The communication processor is an optional module. Since all relays have one common terminal, all power supplies (there can be one or several) associated with the outputs to be driven must have one common connection. In plc, a very common category of input and output interfacing module is discrete. Notice, too, that the diagram of Figure below includes two separate power sources, one providing power for LT1 and the other providing power for K1 and LT2. Lamp LT2 is an AC lamp having it’s own AC source. Output module is use for interfacing between output load and processor, the output modules has a function similar to that of the input modules except in reverse order. A PLC relay output unit with three isolated FORM C contacts is shown in Figure below. This can still be a problem if the coil is highly inductive because the voltage and current will be so far out of phase that some voltage will still be present when the current crosses zero.
