ArmorPOINT RTD and Thermocouple Input Modules 3 Environment and Enclosure ATTENTION: This equipment is intended for use in overvoltage Category II applications (as defined in IEC 60664-1), at altitudes up to 2000 m (6562 ft) without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR 11.
ArmorPOINT RTD and Thermocouple Input Modules About the Module The ArmorPOINT™ I/O family consists of modular I/O modules. The sealed IP67 housing of these modules requires no enclosure. Note that environmental requirements other than IP67 may require an additional appropriate housing. I/O connectors are sealed M12 (micro) style. The mounting base ships with the module. The 1738-IR2M12 module is shown here.
ArmorPOINT RTD and Thermocouple Input Modules 5 Mount the I/O Base Mount the I/O base on a wall or panel, using the screw holes provided in the base. The module must be mounted on a grounded metal mounting plate or other conductive surface.

ArmorPOINT RTD and Thermocouple Input Modules Communicate with the Module I/O messages are sent to (consumed) and received from (produced) the ArmorPOINT I/O modules. These messages are mapped onto the processor’s memory. The ArmorPOINT RTD I/O input module produces 6 Bytes of input data (scanner Rx – status) and fault status data. The ArmorPOINT thermocouple I/O input module produces 8 Bytes of input data (scanner Rx – status) and fault status data. They do not consume I/O data (scanner Tx).
