SLC RetroPAK Controller

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).
