POINT I/O 2 and 4 Relay Output Modules 9 Mount the I/O Base To mount the I/O base on the DIN rail, proceed as follows: 1. Position the mounting base vertically above the installed units (adapter, power supply or existing module). Slide the mounting base until the interlocking side pieces engage the adjacent module or adapter. 31586 2. Slide the mounting base down allowing the interlocking side pieces to engage the adjacent module or adapter. 3. Press firmly to seat the mounting base on the DIN rail.
POINT I/O 2 and 4 Relay Output Modules Install the Module The module can be installed before or after base installation. Make sure that the mounting base is correctly keyed before installing the module into the mounting base. In addition, make sure the mounting base locking screw is positioned horizontal in reference to the base. 1.
POINT I/O 2 and 4 Relay Output Modules 11 Make sure the DIN-rail locking screw is in the horizontal position. Turn the keyswitch to align the number with the notch. Notch position 1 is shown. 1734-TOP Base 45697 WARNING: When you insert or remove the module while backplane power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.
POINT I/O 2 and 4 Relay Output Modules 1. Insert the end opposite the handle into the base unit. This end has a curved section that engages with the wiring base. 2. Rotate the terminal block into the wiring base until it locks itself in place. 3. If an I/O module is installed, snap the RTB handle into place on the module.
POINT I/O 2 and 4 Relay Output Modules 13 6. Use a small bladed screwdriver to rotate the orange base locking screw to a vertical position. This releases the locking mechanism. 7. Lift straight up to remove. Communicate with Your Module I/O messages are sent to (consumed) and received from (produced) the POINT I/O modules. These messages are mapped onto the processor’s memory. This POINT I/O output module does not produce input data (scanner Rx). It consumes 1 Byte of I/O data (scanner Tx).
