Three variations of the DigiRail are available, a dual channel analog input module, a dual output relay/timer module and a four channel counter/digital input module. The DigiRail are ideally suited for industrial environments. The inputs are isolated from the output and power supply thus providing electrical protection and eliminating ground loop effects. All modules mount on 35mm DIN Rail and are configurable via the free downloadable software. DigiRail-2A, Dual Channel Universal Analog Input ModuleThe DigiRail-2A has two analog inputs which are programmable for thermocouples (J, K, T, E, N, R, S, B), Pt100, mV, V, mA. The inputs are read via a two wire RS485 network using Modbus RTU protocol. The two inputs are electrically insulated from the serial interface and the module supply. Features include: Analog inputs: programmable for thermocouples (J, K, T, E, N, R, S, B), Pt100, mV, V, mA Cold junction compensation for thermocouples and compensation for Pt100 3-wire cables Open loop detection for thermocouples, Pt100 and mV Sampling rate for 1 analog input: 10Hz for mV, V and mA. 5 Hz for T thermocouples and Pt100 Analog input resolution: 17 bits DigiRail-2R, Dual Channel Relay/Timer Ouput ModuleThe DigiRail-2R has two 8A SPDT relays which may either be used as standard relay outputs or as timer relays. The relays are controlled via communication over an RS485 network with Modbus RTU protocol. The outputs are electrically insulated from the serial interface and the module supply. Features include: Two independent outputs, with relay SPDT, 8 A, 250 Vac 32 bits timers (up to 4.294.967.295 hundredths of seconds) optionally used for activating each relay 1000 Vac dielectric strength between open contacts DigiRail-4C Four Channel Counter/Digital Input ModuleThe DigiRail-4C has four digital inputs which can be used to detect the "On/Off" state of a discrete input signal or as an input counter. The inputs are read via a two wire RS485 network using Modbus RTU protocol. The inputs are electrically insulated from the serial interface and the module supply. Features include: 4 Digital inputs which can accept signals up to 35 Vdc Maximum count frequency of 1000 Hz for signals with square wave and working cycle of 50%. Input 1 can be configured as a high speed counter for for a frequency of up to 100KHz 32 bit counting capacity (per input) Special counting capable of counting pulses in given time intervals (pulse rate) and retaining peak counting in given time intervals (peak rate) Software DigiConfig Software DigiRail Configuration is done via the RS485 interface by using Modbus RTU commands. The free DigiConfig software, available as a download, 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. FieldChart Supervisory and Data Acquisition Software (Lite version available as a free download) FieldChart is a software used for monitor and register data acquired from NOVUS products. It generates real time trends and data lists that can be exported in usable formats like a spread sheet. There are two versions available: FieldChart-Lite and FieldChart-64C. The FieldChart-Lite can register 8 simultaneous channels and it is available for free. The FieldChart-64C can register up to 64 simultaneous channels.
