Product Details

The AB 1756-OB16E module is a ControlLogix DC digital output module. It has been fused electronically by group and it has 16 outputs total with 8 points per group. A Removable Terminal Block housing, or RTB housing, is necessary before installing it to a compatible ControlLogix chassis. For this module, the can use the AB 1756-TBNH RTB or the AB 1756-TBSH RTB, which both have 20 pins. Note that it is necessary that the chassis and the power supply be installed and grounded before installing this module with the RTB. By using the RSLogix 5000 programming software, it is possible to configure the 1756-OB16E module's transition from the program state to fault state, the output state in fault mode, or the output state in program mode. Other features of this module are multiple output point densities, configurable point-level output states, isolated and non-isolated varieties of output modules, and the output data echo feature.

The 1756-OB16E module has a voltage category of 12 to 24 Volts DC source voltage, as well as an operating voltage of 10 to 31.2 Volts DC. Its total backplane power is 1.32 Watts and a current draw of 250 milliamps at 5.1 Volts and 2 milliamps at 24 Volts. It also has a maximum of 1 milliamp per point of off-state leakage current and a maximum of 400 mV DC voltage at 1 Amp on-state voltage drop. Its maximum current per point is 1 Amp at 60 degrees Celsius and its maximum current per module is 8 Amps at 60 degrees Celsius. This module has been routine-tested at 1350 Volts AC for 2 seconds and it has a continuous isolation voltage of 250 Volts. Its minimum load current is 3 milliamps per point and its typical surge current is 2 Amps for 10 seconds per point, which is repeatable every 2 seconds at 0 degrees Celsius. The power dissipation of this module is a maximum of 4.1 Watts at 60 degrees Celsius, while its thermal dissipation is 13.98 BTU/hour. It has an output delay time of 70 microseconds nominal/maximum of 1 millisecond from off to on and 360 microseconds nominal/maximum of 1 millisecond from on to off. Its operating temperature is between 0 and 60 degrees Celsius and its non-operating temperature is between -40 and 85 degrees Celsius. This module also allows for the modification of the states in the fault mode and the states in the program mode. The options for both modes are on, off, or hold the last state. Both of them have the “off” setting set by default.
