Signal Conditioning & I/O By: YH Goh Technical Evangelist RLC AP

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

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

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

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

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

Signal Converters - Analog Converters make equipment compatible Example – Analog to Analog –PLC with 4-20 mA inputs –Sensors with varying signal outputs

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

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

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

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

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

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

Comms. Converter Products ICM4 –RS232 to RS485 Converter, not-isolated ICM5 –RS232 to RS485 converter with isolation

Signal Isolation Isolators prevent ground-loops Example –Drive with high potential on output –PLC with non-isolated input –Most of our converters have isolation ie ICM5
