PLC-2 Output Module
Description

O tomto produkte

Tu je všetko, čo potrebujete vedieť


The PLC-2 family of PLCs manufactured by Allen Bradley are now obsolete but you can continue to receive support from Northern Industrial. 1771-OBD modules are DC output modules with 16 output points, a user supply voltage of 10...60 VDC and a maximum output current of 2 A per output. This output module is able to be installed on a number of Allen Bradley universal I/O chassis, including the 1771-A1B, 1117-A2B, 1771-A3B and the 1771-A4B, and is fitted in any slot except the furthest left. 

Each of these modules also have LED indicators so that the user can see the status of the DC output module, with green LEDs indicating that everything is operating normally and red LEDs to show when there is a problem. For more detailed technical information about the Allen Bradley 1771-OBD, please see the specifications table below.
