The 1771-JMB mounting board can be used with 16, 1781-series slim, miniature or standard size modules. The terminal block accepts ring or spade lugs, and insulated wire with stripped ends. Each power side point is individually isolated from each other. The signal side has a common logic supply bus (+Vcc and dc return) shared with each of the modules. The 1771-JMB has an edge connector. The 1771-JMBH has both an edge and a header connector. Both models have a jumper connecting power from the ribbon cable. Specify 1781-CxEx Cable. Assembly for 1771-JMB or JMBJ; or 1781-CxHx Cable Assembly for 1771-JMBH or 1771-JMBHJ. 1771-JMBxx is not available for mounting on DIN-rails.

  • Logic Supply +Vcc (+5, +15 Or +24 V Dc) And Dc Return Is Supplied Throughthe 2 Terminal Logic Supply Connector, Marked With + Or –
  • Logic Supply Dc Return Is Connected To All Even Pins Of The 50 Pin Edge Card Connector
  • Signal Pin Is Pulled Up To +Vcc When Not Asserted, Down To Dc Return When Asserted.
  • Power-Side Terminals Are Polarized For Dc Applications, And Non-Polarized For Ac Applications.
  • The Backplane Is Shipped With A Jumper Configuration To Supply The Logic Voltage Through Pins 1 And 49 Of The Edge Connector. If Logic Voltage Is Not Desired On These Pins The J Suffix.
  • Logic-Side Connector Pin Numbers Are For 50 Pin Connector.

1781-Series Quad Modules are available in all of the field voltages as the 1781-Series of Slim Modules or the WRC4-Series of modules. They provide four I/O circuits in one package with an integral LED for each circuit. The 1781-Series of Quad I/O Modules are compatible with the de facto industry standard footprints, however, attention should be given to applications where dc inputs and outputs are involved to confirm the proper polarity. Different vendors have implemented these functions in different ways. WRC offers several different versions allowing the user to meet the polarity needs for your application. Refer to the application notes section of the catalog which discuss sourcing and sinking applications. UL recognized and CE compliant are standard.
