Overview

The Model 5504 Thermocouple input module adds eight thermocouple inputs to the 5000 Series input/output system. Up to eight model 5504 modules may be connected to the I/O bus, for a total of 64 thermocouple inputs per bus. The 5504 module can be used with J, K, E and T type thermocouples or 0 to 80 millivolt input signals.

The 5504 module provides an iso-thermal block for maintaining the thermocouple termination wiring at a know temperature. The temperature of this block is monitored to provide cold junction compensation.

The 5504 module uses a 20000 count, integrating, analog to digital (A/D) converter. A single chip microcontroller with integral watchdog timer operates the A/D, linearizes and scales the output data and communicates over the I/O bus.

All inputs are transient protected and optically isolated from the main logic power.
