Limit Alarms (with DC output) AE-UNIT

RTD ALARM

Functions & Features

• Providing SPDT relay outputs at preset input levels

• Direct input from an RTD

• Dual (Hi/Lo) trip

• Additional isolated DC output proportional to the

temperature

• Linearization

• Burnout protection

• "Active bridge" circuit containing two constant current

sources allows large leadwire resistances up to 200 Ω

• Energized or de-energized coil at a tripped condition

selectable

• Thumbwheel switch adjustments

• Relays can be powered 110 V DC
