Electronics

• Display

10 segment LED array, sequential lighting related to flow rate and flashing when trip point exceeded
 

• Output Signals

Relay: SPDT, 1A @ 24 Vdc, 120 Vac Analog: 4-20 mA trending*
Serial: RS232C I/O
*500 ohm maximum load; user scalable, general purpose, uncalibrated output proportional to flow rate for trend monitoring or assignable to temperature; fault indication per NAMUR NE43 guidelines, user-selectable for high (>21.0mA) or low (<3.6mA) default
For linearized and calibrated analog outputs, see FCI’s line of thermal mass flow meter products
 

• Operation

Two top-mounted buttons to program switch/trip point, zero and span setting, fail-safe, relay hysterisis and relay time delay; button operation may be user disabled to prevent unwanted changes; all set-up function are also user programmable via the RS232C serial port
 

• Trip Point Hysteresis Control: 0-100% of span

• Trip Point Time Delay: user settable for 0-65,000 seconds

• Input Power

 24 Vdc (21.5 Vdc to 30Vdc); 2.5 watts maximum
 

• Operating Temperature

 -40°C to 160°F [-40°C to 71°C]
