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
Specialty Modules • Relays • 3-phase monitor • Power Supplies
Relays Function: Switching, 3 phase and on/off function -Solid State Relay (RLY6) -3 Phase Solid State Relay (RLY7) -Form A/ C Relay (AVMR/ RSRLYB)
Power Supply -24VDC@0.65mA from Univ Power Supply (PSDR6) -24VDC@1A from Univ Power Supply (PSDR7) -24VDC@0.1A from 120/220AC Supply (PSDR12) -24VDC@1A from 120AC Power Supply (PSDR13)
