Terminal Designations
NOTES:
1.
The standard Single Alarm unit (1PRG) utilizes a DPDT relay.
2. Terminal blocks can accommodate 14-22 AWG solid wiring
(torque to 4 inch-pounds, maximum).
KEY:
+IN/–IN = Current input to HIM from HART device +TX = Transmitter Excitation Current
+I/–I Source = Analog Source Output
+I/–I Sink = Analog Sink Output
A/B = MODBUS Output
NO/NO# = Normally Open
NC/NC# = Normally Closed
CM/CM# = Common
DC/DCC = 24VDC Connection
(AO#) = Analog Output
