Digital Inputs: 16
4 in stock, immediate despatch
Low-cost Modbus RS485 based remote IO units, which provide a simple way for integrating analogue or digital signals to supervisory SCADA systems. The MBIO-16DI has 16 opto-isolated digital inputs that can also be used as 32-bit counters.
The counters operate in three modes.
In mode 0: All the counters are disabled.
In mode 1: The counters are 32 bit counters allowing a count value from 0 to 4294967295. The count value can be cleared by writing a zero to the associated registers or preset to any other value using the same method.
In mode 2: The inputs are connected as up/down counters. Input 1 will increment counter 1 whilst input 2 decrements counter1. In the same way, inputs 3&4 operate counter 2, inputs 5&6 operate counter 3 and inputs 7&8 operate counter 4,etc.
When the input filter is configured for > 10ms (Input Filter > 1), then the 16 counters are saved in non-volatile memory and the count value will be saved when the power fails.
The format of the registers allows the status of the inputs to be read as either single bits or all at once as a single register on the Modbus network.
IOStudio is a free software package used to configure the communication settings for IO modules on the Modbus network. Once a module is detected, it is possible to view real-time data of the module directly on the PC and it can be used for diagnostic purposes as well.
