【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 a DC output module with 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) electron fusion groups of eight (8) channels each. The module is typically used to drive 24VDC rated devices such as relay coils, solenoid drive devices, indicators, alarms, and other similar electrical loads.
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; 1756, A10; 1756-A13 and 1756-A17. In addition, it can be used as a local or distributed I/O component.
The 1756-OB16E 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 2 A, 10 ms per point, repeated every 2 seconds at 24 volt DC at 0°C(32°F). 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)).
