【英文介绍】
The Allen-Bradley 1956-OB16E is a discrete output module that is part of the ControlLogix Programmable Automation Controller (PLC) platform. The module is specifically designed for DC output modules and offers an output voltage range of 10-31.2 VDC and a nominal value of 24VDC. It has sixteen (16) output channels divided into two (2) electronic fuse groups, each group of eight (8) channels. The module is typically used to drive devices with a rated voltage of 24VDC, such as relay coils, solenoid drive devices, indicators, alarms, and other similar electrical loads.
The 1756-OB16E is a single slot wide module that is compatible with any 1756 ControlLogix controller. It can be mounted on any 1756 ControlLogix rack, especially the 1756-A4; 1756-A17; 1756-A10; 1756-A13 and 1756-A17. In addition, it can be used as a local I/O or distributed I/O component.
The 1756-OB16E offers an output current of 1 A@ 60 °C (140 °F) per channel or 8 A@ 60 °C (140 °F) per module. It has A surge current rating of 2 A, 10 ms per point, and is repeatable every 2 seconds @ 0 °C (32 °F) @ 24V DC. In addition, the module has a minimum load current of 3 mA per channel.
Each set provides built-in electronic fuses. The turn-off to turn-on output delay time for each output channel is 70 μs (nominal value) /1 ms (maximum value), and the turn-off critical delay time is 360 μs (nominal value) /1 ms (maximum value). It draws 250 mA of current from the backplane at 5VDC and 2 mA at 24VDC, while the backplane requires 1.32 W of total power and a maximum power consumption of 4.1 W @ 60 °C (140 °F).
The voltage class of the 1756-OB16E module is 12 to 24 volts DC supply voltage, and the operating voltage is 10 to 31.2 volts DC. Its total backplane power is 1.32 watts, with a current consumption of 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 1 amp on-off voltage drop. At 60 degrees Celsius, the maximum current per point is 1 amp, and at 60 degrees Celsius, the maximum current per module is 8 amps. The module has been routinely tested for 2 seconds at 1350 volts AC with a continuous isolation voltage of 250 volts. Its minimum load current is 3 mA per point, typical surge current is 2 amps per point for 10 seconds, and can be repeated every 2 seconds at 0 degrees Celsius. The module has a maximum power consumption of 60 watts at 4.1 degrees Celsius, while its heat dissipation is 13.98 BTU/ hour. It has a nominal output delay time of 70 microseconds/maximum 1 millisecond (from off to on) and an output delay time of 360 microseconds (nominal value/maximum 1 millisecond). Its operating temperature is between 0 and 60 degrees Celsius, and its non-operating temperature is between -40 and 85 degrees Celsius. The module also allows modification of the state in fault mode and the state in program mode.
