CAS DataLoggers Digital Input Module Novus DigiRail-4C

The DigiRail-4C Digital Input Module with Modbus RTU communication interface provides a simple way for integrating analog or digital signal to supervisory systems. The DigiRail-4C features four digital input/counter signal channels. The input signals are isolated from power, protecting the electrical instruments by eliminating ground loop effects. This substantially reduces undesirable interferences and instabilities in sensor measurements. Configuration DigiRail Configuration is done via the RS485 interface by using Modbus RTU commands via the digital interface by using the Windows-based DigiConfig software. The DigiConfig software allows for configuration of all DigiRail features as well as complete calibration and diagnosis. It automatically detects active devices in the Modbus network and permits configuration of all parameters. Specifications Digital inputs: in voltage, 4 to 35V to activate internally limited current in 5 mA. Power: 10 to 35 Vdc, 50mA maximum current. 2-wire RS485 communication with Modbus RTU protocol. Configurable address and baud rate (1,200 to 115,200bps). LED indicators for communication and status. Key for resetting communication parameters to original factory default. Isolation: 1000 Vac from outputs and power or communication. Communication and power are not isolated from one another nor are the analog inputs from each other. Every two digital inputs are isolated from other pairs of same inputs. Windows based configurator software. Dimensions: 72 x 78 x 19mm. Mounting: 35mm DIN rail. Refer to drawing. Working temperature: 0 to 70°C
