604 SLCR Controller Board
The Automation & Electronics 604 SLCR is ideal for many Remote Terminal Unit (RTU) applications.
The 604 SLCR is designed to provide local and remote monitoring and control functions at a reasonable price. It has a built in power supply, serial port, and a compliment of useful inputs and outputs.
Used in conjunction with Automation & Electronics SST-9600TM radio or other types of communication equipment, the 604 SLCR can also be easily integrated into a wide variety of SCADA systems.
With the power of the Automation & Electronics LAD language, and the available expansion modules, the 604 SLCR can also be scaled up to perform more complex automation tasks.
Features
General
- Two selectable 1-5 VDC or 4-20 mA 12-bit analog inputs
- Two optically isolated 12 VDC pulse inputs
- Four optically isolated 12 VDC digital inputs
- Four 12 VDC 100 mA digital outputs
- Two form C latching SPDT relay outputs
- Two expansion connectors for interfacing to added input and output devices
- Built in RS-232 serial communications port
- Expansion connector for added serial communications equipment
- Recognizes MODBUS communications protocol for integrating with SCADA systems.
- Built in power supply provides power for the 604 SLCR, 12 VDC backup battery charging, 24 VDC loop supply, 12 VDC external accessories, and 8.5-13.5 VDC (adjustable) external accessories.
- Backup battery operating mode allows the 604 SLCR to continue to run off of an external 12 VDC battery in the event of an AC power failure
- Eight option switches for programming flexibility
- Communication address switches allowing addresses from 0 to 255 to be configured.
- Status indicator LEDs for communications, pulse inputs, discrete inputs, and relay outputs.
- 120 VAC 0.5 A fused heater output connector.
