Page 5: What Is The Gpio Terminal Block
You connect the terminal block to the IF5 with a 25-pin GPIO cable (P/N 236-057-001). The block provides access to each of the four general purpose inputs and outputs on the IF5 via standard screw terminals. -
Page 6: About The Terminal Block Connections
About the Input, Output, and Power Terminal Connections The terminal block provides standard screw terminals that you use to connect industrial control wiring to the IF5 GPIO and power interfaces. The screw terminals are located inside the terminal block on the main circuit board and are arranged as shown in the next illustration. -

Page 10: Using The Terminal Block
Using the Terminal Block This section explains how the terminal block connects to the IF5 GPIO interface and how you connect devices to the terminal block input, output, and power terminals. About the IF5 GPIO Interface The IF5 reader has four general purpose input and output interfaces. - Page 11 • Supply the input interface with power from the IF5. • Isolate the IF5 from the input power source. • Use an open collector solid-state drive from a remote device to control the inputs. For more information, see the next examples. GPIO Terminal Block User’s Guide...

Page 17: Switching The High Side Using If5 Power
Switching the High Side Using IF5 Power The GPIO Terminal Block is factory configured for high side switching, with power coming from the IF5. Only the single output being switched will be affected if the interface cable fails. This configuration supports many indicator lamp applications. -

Page 19: Switching The High Side Using External Power
Switching the High Side With External Power Note: If the IF5 ground is not connected to the external power ground, the output terminal LED will behave unpredictably, but will light up if there is a sneak path in the chassis ground. GPIO Terminal Block User’s Guide... -
Page 20: Driving A Dc Relay To Control An Ac Load
Driving a DC Relay: The external relay provides dry contacts for controlling the AC motor. Note: In many installations, the relay and AC wiring must be placed in an enclosure that meets local fire code regulations. GPIO Terminal Block User’s Guide... -
