The Allen-Bradley 5094-RTB3TXT Flex 5000 Removable Terminal Block (RTB) is a CJC terminal block with screw-type terminals. This RTB belongs to the Flex 5000 terminal base assembly product line. A complete terminal base assembly comprises a mounting base like the 5094-MB or the 5094-MBXT mounting base and an RTB like the 5094-RTB3TXT Removable Terminal Block. Each part must be ordered individually. The Flex 5000 I/O modules require a terminal base for installation and for connecting the field-side wiring. The 5094-RTB3TXT Removable Terminal Block has a built-in Cold Junction Compensation (CJC) thermistor which provides cold junction compensation for installed Flex 5000 Thermocouple modules. On the front view of the 5094-RTB3TXT Removable Terminal Block are key switches used for setting the module position, and there is also an I/O module guide rail and an edge connector for proper module installation.

The 5094-RTB3TXT Removable Terminal Block has 100 milliamps of maximum input rating per channel and an SSV output rating of 1.8 Amps. It has an operating input range of 18 to 32 Volts DC and a total module current rating of 10.0 Amps. The 5094-RTB3TXT Removable Terminal Block has 250 Volts AC of continuous isolation rating between the chassis and Sensor Actuator (SA) and between the I/O channels and chassis. It has screw-type terminals (per channel) for fastening the I/O SSV wiring, module commons, power, customer-supplied external power, and the embedded CJC thermistor to the terminal base. The 5094-RTB3TXT Removable Terminal Block is built for extreme and harsh environmental conditions and it has an open style design that fits into industrial enclosures. The 5094-RTB3TXT Removable Terminal Block has a -40 to 70 degrees Celsius rated operating temperature range and it is designed for use within a 5 to 85% non-condensing relative humidity range.
