The P470 is a standalone 8-channel thermocouple simulator. It is intended for system-level testing of process control systems, FADEC engine controllers, and other critical systems.
It includes eight independent, isolated channels that can simulate all common thermocouple types or generate direct millivolt outputs, and includes thermocouple fault simulation. Outputs feature 20 bit resolution and damage protection up to 240 volts RMS.
Any P470 channel can use the internal reference junction sensor, either of two external RTD sensors, or software-simulated reference junction temperatures.
Both USB and Ethernet interfaces are provided. Control is via text commands or through the internal web page server. Only a web browser is needed to exercise all P470 functions, but the simple ascii command set facilitates integration into larger user scenarios.
The P470 includes built-in-self-test and a test connector which allow in-system calibration check without removing field wiring.
Four versatile digital I/O ports are provided, each CMOS/TTL compatible and capable of driving relays or LEDs.
The P470 is compatible with the Highland model J470 isothermal thermocouple termination box and with the J475 DIN rail termination panel.
