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

3
Fundamentals

• Digital signals
• Frequency (speed) of signal varies as measurement
  varies

4
Fundamentals, contd.

• Digital signals
• Frequency (speed) of pulses varies as measurement
  varies
• Typical digital sensors

5
Fundamentals, contd.

• Analog
• Voltage or current
• Signal level varies as measurement varies

6
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

8
Analog to Analog Products

• IAMA Universal Signal Conditioner
• W/ isolation
• ITMA
• Thermocouple to analog
• IRMA
• RTD to analog

9
Signal Converters - Digital

• Example Frequency to Analog
• Analog input devices
• Pulsed type sensors

10
Digital to Analog Products

• IFMR
• Speed Switch (Frequency to Alarm)
• IFMA
• Frequency to Analog Converter

11
Signal Converters Analog to Communications

• Signal to Data Communications
• Allow PCs or PLCs to monitor signal via
  communications

12
Signal to Comms. Products

• IAMS
• Analog (Volt/Current to Communications)
• ITMS
• TC/RTD (temperature sensors)

13
Signal Converters Comms. Converters

• Data to Data Communications
• Allow different devices to communicate with each
  other

14
Comms. Converter Products

• ICM4
• RS232 to RS485 Converter, not-isolated
• ICM5
• RS232 to RS485 converter with isolation

15
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

16
Specialty Modules
