The PLC 1756-OA16I requires use of Removable Terminal Block (RTB) to provide wiring connections to the electrical loads connected to each of the module’s output channels. Compatible terminal blocks are 1756-TBCH and 1756-TBS6H. Each channel of this module has an output delay time of 9.3 ms @ 60 Hz and 11 ms @ 50 Hz, both for Off to On transition and 9.3 ms @ 60 Hz and 11 ms @ 50 Hz for On to Off transition. This moduel has a current draw of 300 mA at 5.1 VDC and 2.5 mA at 24VDC while the total backplane power requirement 1.59 Watts.
The 1756-OA16I is a single slot module that is mounted to any 1756 chassis. Compatible chassis are 1756-A4, 1756-A7, 1756-A10, 1756-A13 and 1756-A17. This module may also be installed in the local rack, along the ControlLogix controllers or to a remote I/O rack with a 1756 Communication adapter.
The 1756-OA16I supports configuration of fault mode per point. Configurable states are Hold last state, On or Off where Off is default. It also permits configuration of output state during program mode with configurable settings are Hold last state, On or Off where Off is default. This module is not provided with internal fusing however, isolation voltage is present to this module with rating of 250V (continuous), basic insulation type, outputs-to-backplane, and output-to-output.
