1746-OB16 SLC500 Discrete DC output module

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.

1746-OB16E

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.
