EtherNet/IP and PLC-5 I/O Signal Characteristics
The 1771-OGD operates as a PLC-5 digital output interface with TTL-level switching capability. The module uses the PLC-5 chassis backplane for internal operation and an external 5 VDC source for field-side TTL signal delivery. The output stage supports sink-type current operation and interfaces directly with TTL-compatible input devices.
The module is installed through the 1771 rack architecture and follows PLC-5 backplane communication behavior. Proper ESD protection is required during handling and installation to prevent semiconductor output degradation.
Frequently Asked Questions
Q: What type of signals does the 1771-OGD module provide?
A: The 1771-OGD provides 16 TTL digital DC output channels operating in the 5 VDC voltage category.
Q: Does the module require an external power source?
A: Yes. The module requires chassis backplane power and an external 5 VDC supply for TTL output signal transmission.
Q: What is the maximum output current capability per channel?
A: Each output supports a maximum continuous current of 0.20 A in sink operation and 0.001 A in source operation.
Field Installation Guidelines
Install the 1771-OGD module only in compatible PLC-5 I/O chassis positions with correct rack addressing configuration. Verify that the chassis backplane connection is fully seated before applying power.
Use the 1771-WH wiring arm for field connections and maintain separation between TTL signal wiring and high-voltage or high-noise conductors. Connect cable shields according to site grounding standards to reduce electromagnetic interference.
Before handling the module, apply ESD control procedures including grounded work surfaces and personnel grounding equipment. Confirm external 5 VDC supply polarity and voltage level before connecting TTL field devices.
