Technical Specifications 

Information About 1746-OB16

The Allen-Bradley 1746-OB16 is a Discrete output module that is compatible with for use with the SLC500 product family. This module features Sixteen (16) 24VDC output channels that is used to energize electrical devices for implementing manual and automatic control of the process or machines.

The 1746-OB16P is a single slot module that fits to any slot of an SLC500 chassis except the leftmost module which is reserved for the processor or communication module. The 1746-OB16P has a backplane current draw of 0.250 A at 5VDC and 0 A at 24VDC. It has an OFF state leakage current of 1 mA and load current of 1 mA. Eacu channel has a continuous Current of ) 1.5 A @ 30 °C (86 °F) 1.0 A @ 60 °C (140 °F) and continuous Current per module of 6.4 A @ 0...60 °C (32...140 °F).

The 1746-OB16P does not an output grouping or individual channel isolation. It comes with a single group, compsed of the entire Sixteen (16) channels. Each channel has an ON signal delay of 0.1 ms and OFF signal delay of 1.0 ms with ON-state voltage drop of 1.0V at 1.0 A with surge current per point of 4.0 A at 10 ms and surge current per module of 32.0 A at 10 ms.

The 1746-OB16P may be installed in the local chassis, along the processor or act to a distributed I/O station, along a communication adapter.

The 1746-OB16 SLC 500 Digital DC Output Module by Allen-Bradley is a DC module with sixteen 24V DC outputs and it is lodged in any free slot in the 1746 I/O Chassis. It has 16 output points and a backplane electrical rating of 0.280A at 5 Volts DC and one of 0A at 24V DC. The 1746-OB16 has a load-dependent maximum signal delay time of 1ms for OFF and 0.1ms for ON and a maximum current loss of 1mA in its OFF state. In its ON state, it has a voltage loss of 1.2 Volts at 0.50A and the minimum load each point can carry is 1mA.

The 1746-OB16 has a nominal input current of 0.5A at 30 degrees Celsius and 0.25 A at 60 degrees Celsius for each output point and it has a gross input current of 8A at 30 degrees Celsius and 4A at 60 degrees Celsius per module. It also has a current surge of 3A for 10ms recurring every 1s at 30 degrees Celsius and 2s at 60 degrees Celsius (140 degrees Fahrenheit). The 1746-OB16 provides voltage isolation between the backplane and the outputs tested at 1500 Volts AC and it has a total heat dissipation of 7.6 Watts. It has a UL-A196, CSA, and C-UL Class I, Division 2 Hazardous Environment ratings, and it is CSA and UL-certified. When operational, the 1746-OB16 has a working temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) at 5 to 95% non-condensing humidity surrounding and it is designed to withstand a 30G operational shock and a 2.5G operational vibration at 57 to 200 Hertz.
