Πληροφορίες για το προϊόν "SC-6104-W5 Fan Coil Unit Controller, 4-ch Relay Output, RS-485"
SC-6104-W5 CR is a fan coil unit controller for HVAC and building automation. It switches four form C power relays from a single isolated AC digital input, so a fan speed sequence can run locally without a remote host controller. Relay status can also be monitored remotely over RS-485.
The module reads a thermistor temperature sensor covering -40°C to +80°C and makes the reading available over DCON or Modbus RTU. Seven coordinated DI/DO functions can be selected to suit the control logic. Each terminal has ±4 kV ESD protection, and the digital input is isolated from the module at 5000 Vrms.
Communication settings include a hardware-fixed baud rate of 9600 bps and software-configurable rates from 1200 to 115200 bps. DCON and Modbus RTU can use different addresses through hardware configuration. Do not switch loads above 550 W (5 A, 110 V) per channel, as this may cause the module to malfunction.
Applications
- Fan coil unit control in HVAC systems
- Building automation and HVAC control
