UNS0881A-PV2
The UNS0881A-PV2 digital input module is a module used to solve digital circuit inputs for PLCs and motion controllers, such as limit inputs, origin inputs, and other digital inputs. These modules typically support level inputs of 0-24V and may have features such as optocoupler isolation, jitter reduction, and signal frequency calculation. In addition, there are also DAMx series modules, which are 2/4-way switch input monitoring and 2/4-way relay output control modules. The communication interface is one RS-485 port, using the MODBUS-RTU communication protocol, powered by a DC9-36V power supply. This module can be applied to various industrial automation measurement and control systems. The switch output can control the output of intermediate relays or indicator lights, and the status signal of the switch can be returned to the host through the switch input. The switch input has a counting function and can be used as a pulse counting input. In addition, there are also digital input modules in the expansion module of PLC, such as the digital input module in the expansion IO module of FX5U series PLC. The different connection methods between expansion modules and CPU modules include expansion cable type and expansion connector type. Taking the extended cable type FX5-16EX/ES as an example, this module has 16 input channels and supports two wiring methods: source and drain. Overall, UNS0881A-PV2 digital input modules play an important role in various industrial automation and control systems, providing flexible and reliable digital signal input solutions.
