PB6DIO - 6 Digital Input/Output Module

The PB6DIO module is an 6 channel digital input and 6 channel digital output module.

The inputs are isolated from the logic by bi-directional opto-couplers. The inputs have internal counters associated with them. These 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.
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.

The 6 digital outputs are open drain MOSFET (N-TYPE). The outputs may be used to drive lamps or external relays when more drive capability is required. The outputs are isolated from the logic and they share a common negative terminal.

The outputs are written to by the Modbus master device such as a PC or PLC. Each output can be individually switched on or off, or all outputs can be set up at the same time by writing a single number to the output register which represents the status of all outputs.
