The USB/TTL interface appears as a virtual serial port (for example COM1, ttyUSB0) at the PC and converts serial data and the DTR and RTS flow control signals to active low TTL level format. By connecting to the target controller programming pins, it addresses low level communication tasks such as processor programming, product debugging and monitoring. It can also be used on all our processor-based products for use with the respective product accompanying MS-Windows© setup and monitoring software |
| The USB/TTL interface connects vertically or horizontally to the target controller. |

| Our current transformer interface converts the 0-5 A secondary current to a 10 VDC voltage signal. Powered by 24 VDC and mounted directly on the transformer terminals it addresses PLC and similar current measurement applications in motor and power line monitoring where 0-10 VDC analog input stages are more widely available. |

The EIA(RS)232 to TTL interface converts the EIA(RS)232 RX, TX, RTS and DTR signals to their respective active low TTL levels. It mainly addresses low level communication tasks such as processor programming, product debugging and monitoring. It can also be used on all our processor-based products (fits directly on their programming pins) for use with the respective product accompanying MS-Windows setup and monitoring software. |

| The EIA(RS)232 isolator galvanically isolates all eight EIA(RS)232 signals between its data set and data terminal ports. It is powered with 230 VAC and features standard 9-pin D-Sub connectors. |

The EIA(RS)232 to EIA(RS)485 interface converts full-duplex EIA(RS)232 to half-duplex EIA(RS)485 signalling. It is powered with 5 VDC at the EIA(RS)485 terminals and data flow is controlled via the DTR or RTS EIA(RS)232 signals. It typically enables a PC to control any of our products having a EIA(RS)485 port. |
|
| The 4 channel QSS solid state switch interface isolates and converts four NPN, active low inputs to activate respective 3 A AC solid state relay (SSR) outputs. It is powered by 230 VAC and the SSR terminals feature their own isolated line connections making it suitable for applications where the line systems are different or control and power lines are isolated. |

The voltage to current interface converts a 0-10 VDC signal to 0-20 mA format typically addressing long cable sensor/actuator analog signalling applications. It is powered with 230 VAC and fits in standard sized aluminium or plastic enclosures. |

The general purpose 24V interfaces fit in standard sized enclosures and address the need for isolation and convertion in the 24 VDC application world:
- The 3-channel EIA(RS)422 to single end 24 VDC typically converts encoder EIA(RS)422 differential signals for use in low-end PLC applications.
- The 4-channel 24 VDC input to uncommitted optocoupler output is typically used in all signal isolation and convertion applications where a 24 VDC input signal is converted to an isolated 10-20 mA control signal. Both optocoupler outputs of each channel are available enabling each channel to be connected in PNP or NPN mode as needed.
- The 4-channel 24 VDC power output interface isolates four 24 VDC NPN controlling inputs to 10-28 VDC, 1 A push-pull outputs, typically in solenoid activating applications.

Our capacitance to frequency interface converts sensor capacitance to a ratiometric frequency output. The sensor capacitance, when sampled, is internally paralleled with the on-board reference capacitor and as such the output mark-space ratio varies to represent the two signal periods: the one generated with the reference capacitor only and the other with the added sensor capacitance. The integration time and accuracy are selected via the on-board jumper straps. It is aimed at simple capacitance detection applications such a water level detection and material humidity. |
