The Allen-Bradley 1756-OW16I ControlLogix discrete output module has a Normally open (NO) contact form having individual isolation. The term "dry contact output module" may also be used to describe this device, which can function at voltages between 5 and 125V dc and 10 and 240V ac.

The 1756-OW16I module has output current rates that are as follows: 1 A at 5-30V dc, 0.5 A at 48V dc, 0.22 A at 125V dc, 1.5 A at 120V ac, and 0.75 A at 240V ac. The pilot duty rating for this module is C300/R150.

The maximum output delay for both signal transitions is 10 ms for each output channel. With a total backplane power demand of 4.4 Watts, it consumes 150 mA of electricity at 5.1V dc.

The highest switching frequency of the 1756-OW16I discrete output module is 1 operation per 3 seconds, or 0.3 Hz, with a mean bounce duration of 1.2 ms, at the rated load. Each output contact is anticipated to operate up to 300 kHz when used with resistive loads and, when used with inductive loads, up to 100 kHz. This module may be configured to keep the default setting as the last state, On or Off, when FAULTED also allows scheduled outputs.

Similarly, output states can be retained at the last stage, with OFF being the default setting while in PROGRAM mode. A Removable Terminal Block (RTB) is included with this module upon shipping. For usage with this module, the RTBs 1756-TBCH and 1756-TBS6H are appropriate.

The output delay period of the 1756-OW16I discrete output module is 10 ms from ON to OFF and from OFF to ON. It dissipates 4.5 Watts at 60 °C and 15.35 BTU per hour in thermal energy. The lowest current load for each output is 10 mA, while the maximum current leakage is 1.5 mA for each point.

The 1756-OW16I discrete output module features a load-dependent switching frequency of 0.3 Hz and an initial contact impedance of 100 Ω at 6V, 1 A. With an estimated contact life of 100 kHz inductive and 300 kHz resistive, it has a mean bounce duration of 1.2 ms.

A planned output with a 16.7-second synchronization time is available from the discrete output module 1756-OW16I. Additionally, it features a basic insulation type that has undergone testing at 1350V ac for 2 s between outputs-to-backplane and output-to-output and a circuit isolation voltage of 250V. The type of its enclosure is open. With a relative humidity range of 5 to 95%, it can function between 0 and 60 °C.
