The TWI-FO and TWN-FO are designed as a low cost alternative to expensive A/D cards on PLC's, computers and data acquisition systems. The TWI-FO and TWN-FO convert and analogue signal into a linear, frequency output signal, with a 50:50 mark space ratio. Ideally designed to be used with a PLC to convert a 4~20mA signal into a 10~1010Hz frequency, (Other calibrations available.) allowing direct connection into a digital input on a PLC (Use with interrupts.) and powered by the PLC's 24Vdc power supply. Refer to 'Connection Diagrams' for the multiple connection variations.
Note: The conversion from TWN-FO to TWI-FO is easily achieved by the removal of two internal links. Refer to ranging information.
