Analog I/O module
16 outputs | V470
Highland Technology, Inc.
FEATURES
- 16 independent, galvanically isolated analog output channels. Each channel is independently programmable for mode and output range
- Voltage mode: provides 16-bit resolution with programmable output voltage ranges from ±25 millivolts to ±12.5 volts
- Thermocouple simulation mode: simulates most common thermocouples: types J K E T R S B and N. NIST-standard lookup tables are included to allow direct entry of simulated temperatures
- Includes four non-isolated precision RTD signal conditioners for reference junction temperature sensing, plus one onboard reference junction sensor
- Any thermocouple simulation channel can be associated with any reference
The V470 provides 16 independent, isolated analog outputs that may be user-programmed to operate as voltage outputs or thermocouple simulators. Users may write temperature or voltage values at VMEbus speed, and the microprocessor will transparently do all necessary calculations and update the channel electronics.
In thermocouple simulation mode, the V470 includes lookup tables for all common thermocouple types, allowing users to write the desired temperature directly to VME registers. Any channel can be associated with any of the reference junction sensors located in the external field-wiring termination panels, or can use the onboard sensor. Cold-junction compensation is via table lookup of thermocouple potential for the type currently selected. Reference junction temperatures are readable.
Up to four output channels may be series-connected to provide outputs up to ±50 volts.
