The 1746-OB32 is a 32 Channel Digital Output Module by PLC. It is a high density low current DC output module, compatible to be fitted in any available slot of 1746 Chassis except slot 0. The voltage output it provides is 24V DC. The 1746-OB32 has 32 outputs with 16 points per common and it has a sourcing operational voltage ranging between 5 and 50V DC. The 1746-OB32 module draws 0.19A of backplane current at 5V DC and it provides an output circuit isolation tested at 1500V AC for 1 minute. It has a maximum signal delay time of 0.1ms in ON and 1ms in OFF mode and the maximum circuit current leakage in the OFF state is 1mA.
The 1746-OB32 has 0.25A at 0-60 Deg. Celsius nominal current on each output point and the minimum current load of 1mA for every output channel. The module has an average 8A nominal current and a 2A current per common. The maximum voltage loss in the circuit in the ON state is 1.2V at 0.5A and it has a surge of 1.0A for 1ms repeatable every 2s across each output point, a power dissipation of 0.172W per point, and a total module heat dissipation of 6.45W. The 1746-OB32’s operating temperature ranges between 0 and 60 deg. Celsius (32 and 140 deg. Fahrenheit) at 5-95% non-condensing humidity and it can withstand an operating shock and vibration of 30G and 2.5G respectively at 10-200Hz. It has a C-UL and UL Listed Industrial Control Equipment for Class I, Division 2, Groups A, B, C, D Hazardous Locations certification, and is rated at the NEMA standard ICS 2-230 Noise immunity.
