The 1756-OB8 is a ControlLogix discrete output module. This module delivers an ouput voltage range of 10-30 VDC with nominal value of 24VDC. It is used to energize electrical loads that operate in DC voltages as well as AC loads, used with an interposing circuitry.
The 1756-OB8 is a single slot module that occupies any available slot of the chassis except the left-most slot which is intended for the ControlLogix processor or ControlLogix communication adapter / scanner module. It is compatible acting as a local I/O component or as part of a distributed I/O system. It may be installed to any available 1756- ControlLogix chassis and operate along standard or power supply modules.
The 1756-OB8 has a backplane current draw of 165 mA at 5.1 VDC and 2 mA at 24VDC while the total backplane power is 0.89 W and power dissipation of 2.5 W @ 60 °C (140 °F) and thermal dissipation of 8.53 BTU/hr. Each channel of this output module can deliver up to 2 Amperes @ 60 °C (140 °F) and 8 Amperes @ 60 °C (140 °F) per module.
This module uses a Removable Terminal Block (RTB) for connecting each channel of the module to the electrical loads. Compatible RTBs are 1756-TBNH and 1756-TBSH while appropriate RTB keying is user-defined, mechanical keying.
