ALARM FEEDBACK
THE ALARM CONTACTS (R) MAY BE CONFIGURED FOR ANY
FUNCTION SHOWN IN FIGURE 12.1, AND MAY BE INDIVIDUALLY
CONFIGURED AS NORMALLY OPEN, NORMALLY CLOSED OR
BLINKER LATCHED CONTACTS.
CONTACT RATINGS:
R1, 2, 3, 4, 5, 6, 7, 8 – 5.0 AMPS AT 250 VAC, 30 VDC
EXTERNAL LOAD – APT & ATT
4-20 mA SIGNAL - 470 ohms MAXIMUM for 99.9% accuracy/750 ohms
MAXIMUM for 99% accuracy
0-10 VDC SIGNAL - 2700 ohms MINIMUM for 99% accuracy and 1000
ohms for 99.9% accuracy.
MODUTRONIC
COMMAND SIGNAL = 4-20 mA
INPUT IMPEDANCE = 150 ohms
