Output Operation and Wiring
The 1769-OV16 uses sinking output circuitry. In a typical DC control circuit, the output provides a current path toward the module’s common when switched on, so the field load and its supply must match the sinking configuration. Confirm the wiring diagram and common-terminal arrangement before connecting field devices.
The 16 outputs form one output group. The maximum continuous current depends on the operating temperature: the module supports up to 1.0 A per point and 8.0 A per module at 30 deg C, reducing to 0.5 A per point and 4.0 A per module at 60 deg C. Both limits must be observed when distributing loads across the channels.
Switching Characteristics and Power Requirements
The specified ON-state delay is 0.1 ms, while the OFF-state delay is 1.0 ms. The listed surge rating is 2.0 A for 10 ms, repeatable every 2 s. The OFF-state leakage current reaches 1.0 mA at 26.4 VDC, which should be considered when selecting field devices with low input-current requirements.
The module draws 200 mA from the 5.1 VDC backplane supply. Check the available controller or expansion-system power budget before adding the module to an existing I/O configuration.
Frequently Asked Questions
Q: How many field devices can the 1769-OV16 control?
A: The module has 16 discrete output channels. The number of devices that can operate simultaneously depends on each device’s current demand, the total module current limit, and the operating temperature.
Q: What is the maximum output current of the 1769-OV16?
A: Each channel supports 1.0 A at 30 deg C or 0.5 A at 60 deg C. The corresponding maximum total continuous current is 8.0 A at 30 deg C or 4.0 A at 60 deg C.
Q: What should be checked before replacing an existing output module with the 1769-OV16?
A: Verify the controller platform, I/O configuration, sinking wiring requirements, field supply voltage, per-channel load current, total current demand, and backplane power capacity. Confirm the terminal layout and wiring compatibility against the applicable technical documentation.
