Allen-Bradley1769-OB16 CompactLogix Discrete output module

The 1769-OB16 is a CompactLogix Discrete output module which operate at a voltage category of 24VDC at a frequency of 47 to 63 Hz. This module has Sixteen (16) outputs in a single group. This module is compatible for use with a 1769 CompactLogix chassis or MicroLogix 1500.

The 1769-OB16 compact solid output module is a device by Allen Bradley with 16 outputs alongside a 24-volt DC voltage source. The 1769-OB16 module has a functioning voltage range between 20.4 to 26.4 volts DC, and it has a delay output voltage of 0.1ms and an off-mode delay output of 1.0ms. The 1769-OB16 has a 200mA draw current at 5.1V, and heat dissipation at 2.11Watt. The 1769-OB16 is a module with a 1.0mA leakage current around a 26.4V DC, and an on-state minimum current of 1.0mA.
The 1769-OB16 has a 1.0V (max) drop voltage (on-state) at a 1.0mA, and with a 1.0 Ampere at 30 deg. Celsius (86 deg. Fahrenheit) and a 0.5 Ampere at 60 deg. Celsius (140 deg. Fahrenheit) current per point (max). The 1769-OB16 also has an 8.0 A at 30 deg. Celsius (86 deg. Fahrenheit) and a 4.0 A at 60 deg. Celsius (140 deg. Fahrenheit) current per module (max), and a current of 2.0 A for 10ms repeatable every 2 s (surge). It is fitted with IEC Class 2 reinforced insulation, which guards against voltage as high as 75 volts DC. It has 8 modules, a single slot width, and can be mounted on a DIN rail or a panel mount. The 1769-OB16 module has dimensions of 4.65 x 1.38 x 3.43 in. (118 x 35 x 87 mm), and a weight of 0.61 lb (280 g).

The 1769-OB16 is a MicroLogix 1500 and 1769 CompactLogix controller compatible module. This electronic module is a Sixteen (16) channel 24VDC discrete output module. This module has a single group of outputs typically used to energize electrical loads operating with 24VDC voltage.

This module may also be used to energize AC loads via interposing function. With interposing function, relays are used wherein the output module energizes the relay coil. AC voltage, such as 120 / 240VAC is terminated across the relay’s contacts to allow passage of AC voltage to the connected electrical load.
