The Allen-Bradley 5094-RTB3I Flex 5000 isolated removable terminal block is an isolated removable terminal block assembly for the Flex 5000 machine control system. The 5094-RTB3I removable terminal block is made to connect to the Flex 5000 I/O terminal base assembly that is required for the installation and the field-side wiring of every Flex 5000 I/O module. A Flex 5000 I/O terminal base assembly consists of a mounting base and a removable terminal block that must be ordered separately and then assembled. Unlike other removable terminal blocks in its class, the 5094-RTB3I removable terminal block comes with built-in channel isolation on each of the input and output terminals that protects them against contact with the live conducting parts.

The 5094-RTB3I removable terminal block has a maximum I/O current rating of 2.0 Amps at 32 Volts DC. It also has a Sensor Actuator (SA) current rating of 10 Amps at an operating voltage range of 18 to 32 Volts DC. Each I/O channel is isolated from the chassis. The 5094-RTB3I removable terminal block has 250 Volts AC continuous isolation between the I/O channels and I/O chassis and between the sensor actuator and chassis. The 5094-RTB3I removable terminal block uses solid or stranded copper wire with 22 x 14 AWG wire size and 3.5 pounds on an inch of approximate terminal screw torque. The 5094-RTB3I removable terminal block has built-in key switches for setting the I/O module positions and an I/O edge connector for proper I/O module installation. On the front of the block are I/O terminal strips for connecting I/O wiring, commons, and power supplies. If an analog I/O module or high-speed counter module is installed, shield bar accessories must also be connected.
