Miscellaneous Features
Auxiliary Output*(optional): Either or both of the two current outputs
can function as an Auxiliary Output which can be scaled from 0-20
mA or 4-20 mA for 0 to 100% for any range. It can be configured to
represent Input 1, Input 2, PV, active Setpoint, Local SP1, Deviation,
or the Control Output.
Transmitter Power: This output provides up to 28 volts DC to power a
2-wire transmitter (it requires the use of Open Collector Output
(Transmitter Power Output) selection or the Auxiliary Output).
Four Local and one Remote Setpoints: Can be configured to provide four
Local and one Remote Setpoints, which are selectable either via the
keyboard or by Digital Input.
Universal Switching Power: Operates on any line voltage from 90 to 264
Vac 50/60 Hz without jumpers. 24 Vac/dc instrument power,
powered by a power supply which provides double/reinforce
insulation or Safety Extra-low Voltage Circuit (SELV) Input, is
available as an option.
Timer: This standard feature provides a configurable time period of 0
to 99 hours, 59 minutes or units of minutes and seconds. It can be
started via the keyboard, alarm 2, or by a digital input. The timer
