3. 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

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

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

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

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

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

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

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

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

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

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

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

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

16. 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

17. Specialty Modules Relays 3-phase monitor Power Supplies

18. 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)

19. 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)
