The 1734D-IA8XOW8 point block AC 16 I/O module is an electronic device by Allen-Bradley with DeviceNet interface, 16 I/O modules, and a point bus expansion port which allows for an additional 12 POINT I/O modules. It has a minimum ON-state voltage rating of 65 Volts AC at a 5 Amps ON state current. It also has a maximum OFF-state voltage of 43 Volts AC at 2.5 Amps. It has a nominal input impedance of 17.0 kVA and is designed with 20 milliseconds of hardware delay input time. The 1734D-IA8XOW8 has an external AC supply voltage between 85 and 134 Volts AC (47 and 63 Hertz) at 120 Volts AC nominal (60 Hertz).

The 1734D-IA8XOW8 has a relay type output module with output voltage ratings between 5 and 30 Volts DC at 2.0 Amps. It also has an output current between 2 resistive amps at 5 to 30 Volts DC. The 1734D-IA8XOW8 can carry a minimum load of 10mA per point at a contact resistance of 30mA (initial) and it has a switching frequency load rate of 1 operation for 3 seconds at 1.2 milliseconds of average bounce time. The 1734D-IA8XOW8 has an indicator light which displays the I/O status and mode. The 1734D-IA8XOW8 has a power consumption of 8.2W maximum at 24 Volts DC and it dissipates 2.0W of heat at 24 Volts DC.
