Input Parameters

• Sensor Input: Provides 4 sensor input channels, which can be configured via software to support 2-wire and 3-wire accelerometers, velocity sensors, or proximity sensors.
• Temperature Input: Equipped with 4 temperature input channels, supporting thermocouples of types E, J, K, and T, as well as 2-wire or 3-wire platinum resistors.

Output Parameters

• Relay Output: 6 relay outputs. Users can use the 1900 configuration software to set the relay contacts to open or close based on the channel status (normal, alarm, and danger).
• Analog Output: 4 analog 4-20mA recorder outputs, which can provide data from any variable of any channel.
• Buffered Output: 1 dedicated buffered output, which can provide signals for each sensor input.

Communication Parameters

• Supports Modbus communication via Ethernet and a software-configurable RS232/485 serial port, enabling data transmission with distributed control systems (DCS), supervisory control and data acquisition systems (SCADA), etc.

Other Parameters

• Power Supply: Typically powered by 18 to 36Vdc, with an optional 110-220Vac external power supply.
• Dimensions:
