Model P470

8-channel benchtop thermocouple simulator

Overview

Features:
  • 8 fully isolated analog output channels, each independently programmable for mode and output range
  • Voltage mode: provides 20-bit resolution with programmable output voltage range of ± 100 millivolts
  • Thermocouple 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 in °C
  • Two precision RTD signal conditioners for external reference junction temperature sensing, plus one on-board RTD reference junction sensor
  • Any thermocouple simulation channel can be associated with any reference
  • Provision for open and reverse thermocouple simulation
  • Separate calibration port allows users to check calibration without moving connectors
  • Compatible with optional J470 isothermal junction box with integrated RTD reference junction sensor or J475 DIN rail field wiring interface board
  • 4 versatile digital input/output lines
  • Full-function Built-In Self-Test (BIST)
  • Ethernet and USB interfaces
  • Controllable via serial ASCII commands or web interface
Description:

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.
