IF61 Terminal block GPIO cable To industrial controls Connecting to the Reader: This example shows an IF61 Fixed Reader connected to the terminal block. Connecting To the IF5, IF30, and IF61 Readers This section explains how the terminal block connects to the IF5, IF30, and IF61 reader GPIO interfaces, and how you connect devices to the terminal block input, output, and power terminals. Note: Connecting the terminal block to the IV7 requires special considerations. For more information and a schematic, see "Connecting To the IV7 Vehicle-Mount Reader" on page 23. About the Reader GPIO Interface The IF5, IF30, and IF61 readers have four general purpose input and output interfaces. Each interface is electrically isolated from the reader and designed for low voltage DC loads. The readers can also supply 12 VDC at 0.5 A to external devices. For more information, see "About the Input, Output, and Power Terminal Connections" on page 8. Connecting Devices to the Input Terminals Each input terminal has four terminal posts: • 12 V • +Input • -Input • Gnd (Ground) 12 GPIO Terminal Block User's Guide
