Product catalog summary
Power Supply: The device operates at a rated voltage of 230 Vac ±10% with a frequency of 50/60Hz.
Inputs: It supports 4 RTD Pt100 sensors with 3-wire connections, featuring removable rear terminals and protection against electrical and magnetic interference. Cable compensation is available for lengths up to 500 meters.
Outputs: Includes 2 alarm relays, 6 fan outputs rated at 230 Vac 1.5 Amp max, and 1 fault alarm relay. Output contacts have a capacity of 5A-250 Vac. It also features Modbus RTU RS485 and optically isolated 4.20mA outputs.
Tests and Performances: Assembled according to CE standards, it offers protection against electromagnetic noise (CEI-EN61000-4-4) and dielectric strength of 1500 Vac. The device operates accurately within ±1% vfs and ±1 digit, in temperatures from -20°C to +60°C, and up to 90% non-condensing humidity. It includes a self-diagnostic feature for temperature sensors and data storage for a minimum of 10 years.
Displaying and Data Management: Features include a temperature display, channel reference display, and multiple LEDs for mode and status indication. It supports temperature monitoring from 0°C to 200°C, with alarm and fan control thresholds. Programming is accessible via a front button, with automatic error display and alarm reset capabilities.
Dimensions: The device measures 210 x 260 x 85 mm with a panel cut-out of 232 x 182 mm, and is colored RAL 7035.
Options: Available in a basic version without RS485 and 4.20mA outputs, or with RS485 output.
