The 1756-OB16E is a single slot width module that is compatible with any 1756 ControlLogix controller. It can be mounted to any 1756 ControlLogix rack, especially the 1756-A4, 1756-A17, etc. In addition, it can be used as a local /O or distributed /O component. This kind of module can be applied flexibly and can form a variety of optical fiber networks.
The 1756-OB16E is a Rockwell Automation module with a variety of functions. It can be used with any 1756 ControlLogix controller, installed on any 1756 ControlLogix rack, and can be used as a local /O or distributed /O component. It provides 1 A output current at 60°C(140°F) per channel, or 8 A output current at 60°C(140°F) per module. It has a surge current rating of 2A, 10 ms per point, repeated every 2 seconds at 0°C(32°F)24 volt DC. In addition, the minimum load current of the module is 3 mA per channel. Each set provides built-in electronic fuses. The turn-off to turn-off output delay time of each output channel is up to 70 s nominal value /1 ms, and the turn-off delay time is up to 360 s nominal value /1 ms. The current it draws from the backplane is 250 mA at 5v DC and 2 mA at 24 V DC, while the backplane requires a total power consumption of 1.32 watts and a maximum power consumption of 4.1 W(60°C(140°f)). The 1756-OB16E module has a voltage class of 12 to 24 volts DC supply voltage and an operating voltage of 10 to 31.2 volts DC. The total power of the base plate is 1.32 watts, and the current consumption is 250 mA at 5.1 volts and 2 mA at 24 volts. It also has a maximum turn-off leakage current of 1 MA per point and a maximum DC voltage of 400 mV at a 1 amp on-state voltage drop. It has a maximum current of 1 amp per point at 60 degrees Celsius and a maximum current of 8 amps per module at 60 degrees Celsius. The module has been routinely tested for 2 seconds at 1350 volts AC with a continuous isolation voltage of 250 volts. The minimum load current is 3 amps per point, and the typical surge current is 2 amps per 10 seconds, repeated every 2 seconds at 0 degrees Celsius. The module has a maximum power consumption of 4.1 watts at 60 degrees Celsius, while its heat dissipation is 13.98 BTU/ hour. The output delay time from off to on is nominal 70 microseconds/maximum 1 millisecond, and the output delay time from on to off is nominal 360 microseconds/maximum 1 millisecond.
