1771-RK

The Allen Bradley 1771-RK is a PLC 5 Rack Keying Bands that comes with 4 analog inputs and 4 analog outputs. This module has an update time of 2 milliseconds, one slot, and a fuse of 3 A, 250 Volts, and Normal-Blow.

Measuring  4.5 x 12.4 x 6.3 inches (115 x 317 x 160 millimeters), this keying band weighs a mere one pound. It functions best at temperatures no lower than 32 degrees Fahrenheit and no higher than 140 and can be stored best at any temperature between -40 and 185 degrees Fahrenheit with a non-condensing relative humidity of 5% to 95%.

This keying band should not be exposed to surfaces or other areas that normally withstand electrostatic charges, as these charges can potentially alter or destroy the part’s memory. Connection or disconnection of this device or any device on the network, while power is being applied, can cause a potentially hazardous electrical arc to occur; always remove power before proceeding.

With an operating shock of 30 G (3 pulses, 11 milliseconds), a nonoperating shock of 50 G (3 pulses, 11 milliseconds), and a backplane current of 1.2 A, this keying band is a powerful device that has passed a number of Electromagnetic Compatibility standards, including  EN 50081-2 EMC - Generic Emission Standard, Part 2 - Industrial Environment and EN 50082-2 EMC – Generic Immunity Standard, Part 2 - Industrial Environment.
