Key Features
- 16 TTL output channels for digital control applications
- 4.5-5.5V DC voltage range with 24mA per point
- Inverted logic requires NOT instruction for proper operation
- Single slot module for SLC 500 chassis
- TTL loads and sink-load display compatible
- Individual channel monitoring and forcing via data table
- Wide operating temperature range -25°C to +60°C
Installation Guidelines (Field Engineer Notes)
Chassis Installation: Insert module into any available slot in SLC 500 chassis. Power off before insertion. Secure with captive screws to 0.6 N·m.
External Power Supply: Module requires external 5V DC power supply for output circuitry. Connect +VDC to common terminal. Use 1.0 mm² wire minimum.
TTL Logic: Module uses inverted logic. A NOT instruction is required in the program to negate the naturally inverted logic.
Programming: View data table in binary, decimal, octal, or hexadecimal. Drag and drop operation supported in programming software.
FAQs
Q1. What type of loads are compatible with the 1746-OG16?
A1. The module is designed for TTL loads and sink-load displays with 4.5-5.5V DC voltage range.
Q2. Why does the module require a NOT instruction?
A2. The 1746-OG16 uses inverted logic. A NOT instruction must be used in the program to negate the naturally inverted logic for proper operation.
Q3. What is the current per output point?
A3. Each output provides 24 mA continuous current. Total module current is 384 mA.
