The Allen-Bradley 5094-RTB3TS Removable Terminal Block is a Cold Junction Compensation (CJC) removable terminal block for the Flex 5000 I/O system. This terminal block belongs to the Flex 5000 terminal base assembly series, which provides base terminations for Flex I/O modules and connections for the field-side wiring. The 5094-RTB3TS Removable Terminal Block together with a suitable mounting base makes up the complete Flex 5000 terminal base assembly. Both the terminal block and the mounting base can each be ordered separately. The 5094-RTB3TS Removable Terminal Block has a front-panel I/O edge connector and I/O module guide rail for holding the modules securely in place and several key switches for setting the module into the correct installed position. It has a rear-ended shield bar for wiring the high-speed counter module and analog I/O module terminal bases.

The 5094-RTB3TS Removable Terminal Block has a maximum input current rating of 100 milliamps and an SSV (sensor sourcing voltage) output rating of 1.8 Amps at 24 Volts DC. The 5094-RTB3TS Removable Terminal Block has a maximum module current rating of 10 Amps and an operating voltage rating of 18 to 32 Volts DC. This terminal block has basic insulation surrounding every conductor, and it has 250 Volts AC of continuous channels to chassis and SA to chassis isolation. It has spring-type terminals (1 per channel) for linking the I/O SSV wiring, connecting commons, backplane power, customer-supplied power, and the embedded CJC thermistor within the terminal block. The 5094-RTB3TS Removable Terminal Block has ATEX, NA, and IECx T4 temperature code ratings and it comes with an open style design that supports industrial enclosures. The 5094-RTB3TS Removable Terminal Block is c-UL-us, CE, RCM, Ex, IECEx, and KCC certified. It has an ambient operating temperature range between -40 and 70 degrees Celsius in a 5 to 95% non-condensing relative humidity range.
