PRODUCT DESCRIPTION
1.1 OVERVIEW
The SLC RetroPAK Controller, Figure 1-1, is a 3x6 instrument with a 6 line 3 bar graph
configurable display, removable rear terminations, and built-in communications. The
controller has two built-in 4-20mA analog inputs, two modular 4-20mA analog inputs, two
milliamp built-in milliamp outputs, three digital inputs and two digital outputs.
1.1.1 Features
Instrument
• 3X6 (72mm X 144mm) instrument with behind panel depth of 15.75 inches (400mm)
• Motorola 68302 processor, including on-chip RISC communications processor
• Universal ac power supply (85 to 250VAC/ 50 to 400 Hz)
• Optional dc power supply (nominal 24V dc)
• 64K bytes non volatile database RAM
• Embedded real-time clock with 1ms resolution
• A Service Manual switch under the front panel which allows a single point output to be
manually adjusted and displayed (Jumper J5 for NEMA 4 as shown in Figure 1-1).
