Basic Product Types n Signal Converters – Convert one type of signal into a different type • Analog signals • Digital signals • Communications n Signal Isolators – Electrically isolate an output signal from an input • Protects input circuits from damage n Special Function Modules – Perform various functions – DIN rail mounted

Fundamentals n Digital signals – Frequency (speed) of signal varies as measurement varies

Fundamentals, contd. n Digital signals – Frequency (speed) of pulses varies as measurement varies – Typical digital sensors

Fundamentals, contd. n Analog – Voltage or current – Signal level varies as measurement varies

Fundamentals, contd. n Analog – Voltage or current – Signal level varies as measurement varies – Typical analog sensors

Signal Converters - Analog n Converters make equipment compatible n Example – Analog to Analog – PLC with 4 -20 m. A inputs – Sensors with varying signal outputs

Analog to Analog Products n IAMA – Universal Signal Conditioner – W/ isolation n ITMA – Thermocouple to analog n IRMA – RTD to analog

Signal Converters - Digital n Example – Frequency to Analog – Analog input devices – Pulsed type sensors

Digital to Analog Products n IFMR – Speed Switch (Frequency to Alarm) n IFMA – Frequency to Analog Converter

Signal Converters – Analog to Communications n Signal to Data Communications – Allow PCs or PLCs to monitor signal via communications

Signal to Comms. Products n IAMS – Analog (Volt/Current to Communications) n ITMS – TC/RTD (temperature sensors)

Signal Converters – Comms. Converters n Data to Data Communications – Allow different devices to communicate with each other

Comms. Converter Products n ICM 4 – RS 232 to RS 485 Converter, not-isolated n ICM 5 – RS 232 to RS 485 converter with isolation

Signal Isolation n Isolators prevent ground-loops n Example – Drive with high potential on output – PLC with non-isolated input – Most of our converters have isolation ie ICM 5
