2020年5月7日 · Rockwell Automation announces that as of May 07, 2020, the FIELD WIRING ARM 21 TRMLS TIN PLATED will be discontinued and no longer available for sale. Customers are encouraged to remove references to the affected product (s).

Allen-Bradley digital dc I/O modules interface to ON/OFF devices such as limit switches, pushbuttons, motor starters, pilot lights, and annunciators. These modules are compatible with all current Allen-Bradley programmable controllers. This saves on spare parts, system engineering, inventory, and training costs. .

Connect your I/O devices to the field wiring arm, 1771-WH, shipped with the module. You can use an ac (24V) output module, 1771-OND series C, to directly drive terminals on an ac/dc (24V) input module, 1771-IND series C, as shown in the connection diagram on

1771-WHFB - this wiring arm uses a 1.5 A fuse for each output. The maximum continuous current should not exceed 1.1 A per fuse. Fused field wiring arms require more clearance than the 1771-WH field wiring arms. If you are installing in a cabinet, make certain that your installation has sufficient clearance for this wiring arm.
