Input Module
You can connect up to four transmitters 4 to 20 mA with 2 or 3 core cables to the input module. Up to a total of four input modules per controller can be installed. Each module consists of three relays. These three relays offer the common outputs SPOC "Error", "Alarm 1", and "Alarm 2". In addition, two alarm levels can be fully configured and can be set to increase or decrease and lock or not lock. The third alarm is made possible by using the relay module.
Relay module
You can add two relay modules to the REGARD 3900 series controller. Each module consists of eight relays. The first relay is specified as the "Error" relay and cannot be reconfigured. The other seven relays can be configured as "Single", "General", or "Voting" alarms. An additional "alarm 3" is offered by the relay module along with a second error threshold. You confirm the alarm relay via a push button on the front panel. The relay works with open or closed circuit currents.
Gateway solution
REGARD 3900 Modbus Gateway is an interface that converts the CAN bus protocol to the Modbus RTU protocol. Thanks to this factor, the gateway allows communication between the REGARD 3900 series control unit (CAN bus) and RVP 3900 (Remote Visualization Panel) or other systems (Modbus RTU). Other gateways that can be used are: Modbus TCP / IP Gateway and PROFIBUS®. You can use this gateway to transfer data to a third party control system.
Installation and installation
The REGARD 3900 and 3920 containers are sturdy dustproof and protected from water spray (IP 65). Thus this control unit can be installed in a safe area. REGARD 3910 is equipped with a display and a built-in circuit board. You can install it easily into the cabinet. Modules can also be installed there.
