Isolated 4-20mA Transmitter Output

Output Source： Rate， total， grand total， max， min， set points 1-8， or manual control modeScaling Range： 1.000 to 23.000mA for any display range

Calibration： Factory calibrated： 4.000 to 20.000=4-20mA output

Analog Output Programming： 23.000mA maximum for all parameters： Overrange， underrange， max， min， and break

Accuracy： ± 0.1% FS ± 0.004mA Note： Although the specification above states very high accuracy， it is based in percent. Therefore， the variance when dealing with very large retransmitted numbers such as those that may be associated with the "Total" variable (up to 9 digits with overflow) will grow proportionay.

Temperature Drift： 0.005% of calibrated span/°C max from 0 to 65°C ambient， 0.01% of calibrated span/°C max from -40 to 0°C ambient Note： Analog output drift is separate from input drift.

External Loop Power Supply： 35 VDC maximum

Output Loop Resistance：
Power supply           Minimum         Maximum

24 VDC                     10 Ohms        700 Ohms

35 VDC (external)     100 Ohms      1200 Ohms

Deadband： 0-100% of span， user programmable

Relay Assignment： Relays may be assigned to rate， total， or grand total.

High or Low Alarm： User may program any alarm for high or low trip point. Unused alarm LEDs and relays may be disabled (turned off).

Relay Operation： automatic (non-latching)， latching (requires manual acknowledge)， sampling (based on time)， off (disable unused relays)， and manual control mode.

Relay Reset： User selectable via front panel buttons， digital inputs， or PC

1. Automatic reset only (non-latching)， when input passes the reset point or total is reset to zero.

2. Automatic+manual reset at any time (non-latching).

3. Manual reset only， at any time (latching).

4. Manual reset only after alarm condition has cleared (latching).

Note： Front panel button or digital input may be assigned to acknowledge relays programmed for manual reset.Time Delay： 0 to 999.9 seconds， on & off relay time delays.Programmable and independent for each relay.

Fail-Safe Operation： Programmable and independent for each relay. Note： Relay coil is energized in non-alarm condition. In case of power failure， relay will go to alarm state.
