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
