The 1746-OB16E Digital Output Module is an electronically-fused 24V DC signal output module which can be fixed on any available slots in 1746 Chassis and it uses a Removable Terminal Block (RTB). It has an operating voltage range between 10 and 30V DC (source) and draws a backplane current of 0.135A at 5V DC. The 1746-OB16E has a load-dependent 1ms signal delay time for both ON and OFF mode and it has a maximum output current leakage of 1mA in its OFF state. The minimum current load available on each point is 1mA and it has an inrush current 2.0A on each point for 2ms repeating every 1s at 30 °C (86 °F). The 1746-OB16E has 0.388W heat dissipation per output point and 7.6W of aggregate heat dissipation on the module. It has an operating temperature bracket of 0-60 °C (32-140 °F) at a relative humidity condition of 5-95% without condensation and it is NEMA ICS 2-230 rated for Noise immunity. The 1746-OB16E has an operational vibration of 2.5G at 10-200Hz and a shock rating of 30G.

Frequently asked questions：

Q : What is the 1746-OB16E?
It is a 16-channel, 24V DC transistor output module belonging to the SLC 500 PLC platform.

Q : What is the difference between 1746-OB16 and 1746-OB16E?
The standard 1746-OB16 does not have electronic short-circuit protection and requires external fusing to protect the module. The 1746-OB16E has built-in electronic protection.

Q : How many commons does the 1746-OB16E have?
It has 2 isolated commons (8 channels per common), allowing you to use two different power sources if needed.

Q : How much backplane current does the 1746-OB16E consume?
It consumes 0.135 A from the 5V DC backplane and 0.0 A from the 24V DC backplane.
