Technical Specifications for 1756-OW16I 

About  1756-OW16I 

The 1756-OW16I has a maximum switching frequency of One (1) operation every Three (3) seconds or (0.3 Hz at rated load) with mean bounce time of 1.2 ms. Each of the output contacts are expected to operate up to 300 kHz when used with resistive loads and 100 kHz when used with inductive loads. Additionally, this module supports scheduled outputs and may be configured to Hold last state, On or Off during when FAULTED with Off as default setting. Similarly, output states may also be held at last state, with OFF as default setting during PROGRAM mode. This module is shipped with a Removable Terminal Block (RTB). Applicable RTB for use with this module are 1756-TBCH and 1756-TBS6H.

The 1756-OW16I’s output delay time for both ON to OFF and OFF to ON is 10 milliseconds and it draws a backplane current of 150mA at both 5.1 Volts and 24 Volts DC and it has a total backplane power of 4.4 Watts. It has a thermal dissipation of 15.35 BTU/hour and dissipates 4.5 Watts at 60 degrees Celsius. Each output can accommodate a minimum current load of 10mA and a current leakage of 1.5 mA per point. The 1756-OW16I contact module has an initial contact impedance of 100 Ohms at 6V, 1A and it has a load-dependent switching frequency of 0.3 Hertz. It has a mean bounce time of 1.2 milliseconds with an expected contact life of 300 kHz resistive and of 100 kHz inductive. The 1756-OW16I has a scheduled output with a 16.7 second synchronization time with respect to Coordinated System Time (CST), and it has a circuit isolation voltage of 250 Volts with a basic insulation type tested at 1350 Volts AC for 2 seconds between outputs-to-backplane and output-to-output. The 1756-OW16I has a designated T4 North America temperature code and an open enclosure. Its operational temperature ranges between 0 and 60 degrees Celsius at a humidity of 5 to 95% without condensation.
