a8888@msa.hinet.net www.jetec.com.tw F-series (F012, F018, F110, F131) Input features With the F-series, the following signals types can be processed: ? Flow measurement: Turbine sine wave (coil) pick-ups, reed switches, hall-effect sensors and other active or passive NPN/PNP pulse signals, NAMUR sensors and

2 or

3 wire (0)4 - 20mA or

0 - 10V DC. ? Temperature measurement: 2,

3 or

4 wire PT100 (PRTD) elements, thermocouple as well as

2 or

3 wire (0)4 - 20mA or

0 - 10V DC signals. Linearization of the input signal, data filter functions and square root calculation are all available to process the input signals. Output features Related to the functionality of the selected model, the follow- ing output features are available: ? Analog output proportional to the flow rate. The active, passive or isolated (0)4 - 20mA or

0 - 10V DC analog output can also be used to control actuators with the PI(D) controllers. ? Transistor or relay outputs for high and low alarms, scaled pulse output, flow-direction as well as the control of valves/relays in batch and level control applications. ? The RS232, RS485 or TTL interface makes it possible to communicate remotely, even with the battery-powered unit. All software parameters can be monitored and modified in addition to the usual transfer of data using the ModBus? protocol. Models F012 Display with external power supply or battery powered F018 Alarm or pulse output, analog output with HART communication F110 Pulse output, analog output, optional RS232/RS485 F131 Bach controller with pulse output, analog output,

2 batching outputs, optional RS232/RS485 Options for hazardous area installation The F1-series can be supplied with certified intrinsically safe to ATEX and IECEx. The basic F0-series have got the following certifications with an ambient temperature of -40 °C to +70 °C (-40 °F to +158 °F). ? The ATEX markings for gas and dust applications are: II
