The Allen Bradley 1734-RTB3S Point I/O Removable Terminal Block Assembly is a removable mounting base with 12 terminal spring clamps that provide installation as well as a termination point for most Allen Bradley 1734 I/O modules. This terminal base is factory wired and therefore does not require additional wiring; it is mounted directly on a DIN-rail to form an interconnect point for the POINT Bus backplane communication and field power-bus distribution. The 1734-RTB3S has a maximum field supply voltage of 300 Volts, with maximum field supply current of 10 Amperes, a maximum signal termination current of 2.0 Amperes, and a voltage termination of 30 Volts. It has an isolation voltage of 250 Volts between the field-side to the system using Basic Insulation Type tested at 1000 Volt AC for 60 seconds. The 1734-RTB3S has 0.34 to 2.1 millimeter square (22 to 14 AWG) solid or stranded copper wire conductor size, with 1.2-millimeter (0.047-inch) maximum insulation strip length, and it has 12 separate terminal locations which are numbered correctly for field wiring. This module should be installed on a DIN Rail by inserting the opposite end of the terminal base block into the base unit and rotating it into the wiring base with a terminal torque of 0.5 to 0.6 Newton-metre until it locks itself in place. It has an operating temperature range of -20 to 55 degrees Celsius (-4 to 131 degrees Fahrenheit) at a non-condensing relative humidity range of 5 to 95% and a storage temperature limit of -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). The 1734-RTB3S can withstand a 30G operational shock, and it weighs approximately 87.0 Grams, with a net dimension of 65 x 12 x 160 millimeters.
