The SC-320 controller is designed to mount on a 35mm DIN rail. The case measures 101H x 45W x 120D (mm). When calculating space requirements for the SC-320, you should allow for an additional 30-50mm above and below the unit for connectors and wiring.
The SC-320 series controller supports one analogue input module with up to 8 channels. The base unit also comes standard with 4 function pins which can be configured as digital inputs if required.
Analogue Input Modules
Analogue Input Modules
The SC-320 series programmable controller does not include analogue output by default, however you may add it if desired. One serial port will be installed as standard, however you must specify whether you would like RS232 or RS485.
- Analogue Output (Isolated)
- AICV-R
- 1 x 4-20mA/0-10V
- Analogue outputs are used to retransmit process variables to PLCs and SCADA systems. They can be used to control outputs, (such as valves, motor drives and chart recorders) or to add a transmitter function to the controller.
- Serial Output
- SCS2S
- RS232 (screw terminal)
- SCS4S
- RS485 (screw terminal)
- Serial outputs are used to set up and calibrate the controller using a PC. They can also be used to drive external printers and modems, communicate to PC’s/PLCs and retrieve logged data. Define Instruments serial output is compatible with SCADA systems.
The SC-320 controller comes standard with 2 relay outputs (5A form A) and 4 function pins which can be configured as digital inputs.
You may also opt to include the following digital I/O expansion if required, which can be used in combination with the standard digital I/O’s. The expansion is factory appended to the side of the SC-320 and increases the total width of the unit to 70mm.
- Digital I/O Expansion
- SC-IO
- 8 x digital inputs, 8 x digital outputs (4 x Form C, 4 x O/C)
The SC-320 series base controller does not include any memory by default. Data-alogging and real-time clock will only be enabled when you opt for this memory upgrade.
- Memory
- SC-RTC-1024
- 1,024KB internal memory upgrade + data-logging and real-time clock
The following programs are compatible with your SC-320 controller:
