POINT I/O 24V dc Digital Diagnostics Input Module Before You Begin The module supports remove and insert under power, auto-address, and auto-baud in compliance with the POINTBus backplane. Each input is a sinking dc input with short-circuit and open-wire detection. The sensor source voltage is derived from the user auxiliary power and used as I/O power. Understand Short-circuit Detection The sensor source voltage (SSV) for each input is protected against short circuits.
POINT I/O 24V dc Digital Diagnostics Input Module 9 Understand Open-wire Detection Sensor source voltage (SSV) current for each input is monitored. Monitoring is accomplished in the SSV leg to accommodate the largest number of sensors possible. For currents below 0.5 mA, a fault signal is issued and the input's LED indicator blinks red. On a per-input basis, the circuit and produced data automatically reset upon removal of the open-wire condition.

Press firmly to seat the mounting base on the DIN rail until the mounting base snaps into place.
POINT I/O 24V dc Digital Diagnostics Input Module 11 Install the Module Install the module before or after base installation. Before installing the module into the mounting base be sure of this. • The mounting base is correctly keyed. • The mounting base locking screw is positioned horizontally referenced to the base. 1734-TB base is shown. Turn the keyswitch to align the number with the notch. Notch position 3 is shown. Be sure the DIN-rail locking screw is in the horizontal position.
POINT I/O 24V dc Digital Diagnostics Input Module Be sure the DIN-rail locking screw is in the horizontal position. 1734-TOP base is shown. Turn the keyswitch to align the number with the notch. Notch position 1 is shown.
POINT I/O 24V dc Digital Diagnostics Input Module 13 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. Repeated electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance that can affect module operation.
POINT I/O 24V dc Digital Diagnostics Input Module Insert the Module on the Base Insert the module straight down into the mounting base. Hook the RTB end into the mounting base end and rotate until it locks into place.
POINT I/O 24V dc Digital Diagnostics Input Module 15 Install the Removable Terminal Block When you connect or disconnect the removable terminal block (RTB) with field-side power applied, an electrical arc can occur. This could cause an explosion in hazardous location installations. WARNING Be sure that power is removed or the area is nonhazardous before proceeding.

POINT I/O 24V dc Digital Diagnostics Input Module Configure the Module Read this section for information about how to communicate with your module. I/O messages are sent to (consumed) and received from (produced) the POINT I/O modules. These messages are mapped into the processor’s or scanner’s memory. This POINT I/O input module produces 1 or 2 bytes of input data based on which produced assembly is selected. The default setup is 2 bytes. It does not consume I/O data (scanner Tx).
