F193 - Modbus display

F193 - Modbus display
with alarms, control and analog outputs

The F193 is a versatile large digit Modbus display. All displayed information and signal outputs are controlled through the Modbus ASCII / RTU communication protocol. Information of nine different tanks or products can be displayed with an automatic toggle function or can be selected by the operator. Off-course, it can also be selected and locked through communication.
Further, up to four control or alarm outputs can be controlled directly or being linked to an alarm status of the nine products: an alarm message will be displayed and the related relay(s) switched. Also available is an analog output signal, fully controlled through the communication. For security reasons, all outputs can be switched-off automatically in case of a communication break-down.
The display shows the actual value, product / tank ID, measuring unit, alarm messages and status.
A wide range of options further enhance this models capabilities, including Intrinsic Safety for hazardous area applications.

Features
• Fully controlled through Modbus ASCII / RTU communication protocol.
• Nine different product or tank values can be displayed.
• Displays actual value, product / tank I.D., measuring unit, status and alarm messages.
• Actual values are operator selectable or with the automatic toggle function.
• Up to four alarm outputs can be controlled through communication or related to actual product values.
• Alarms can be terminated through communication or after operator interaction.
• One analog output controlled through communication.
• Actual value: six large 17mm (0.67") digits.
• Green LED backlight.
• Backup of settings in EEPROM memory.
• Operational temperature: -30°C to +80°C (-22°F to 178°F).
• Very compact design for panel mount, wall mount or field mount applications.
• Rugged aluminum or GRP field mount enclosure IP67 / NEMA4X.

Applications
Local indication and monitoring of process parameters where the actual information is provided through a Modbus communication link and not a sensor.

Flowmeter Inputs
• None.

Pulse Outputs
• None.

Alarm Outputs
• Function: Configurable alarm outputs controlled through communication or related to the actual product / tank values.
• Type: Up to three passive NPN transistors or active PNP transistors or up to four isolated electro-mechanical relays.

Analog Outputs
• Function: Re-transmitting any value set through communication - the output can be scaled to any previously set range.
• Type: One passive isolated, floating or loop powered 4 – 20mA output or one active (0)4 – 20mA or 0 – 10V DC output.
