2.3 – INPUTS/OUTPUTS

Analog Inputs

.  Dual inputs are field configurable via

jumper for 0-5VDC, 0-10VDC, or 4-20mADC.  One is
reserved for temperature input; the other for use with
special function.

Analog Outputs

.  Three standard and one selectable

outputs are individually configurable via jumper for 0-
5VDC, 0-10VDC or 4-20mADC.

Digital Inputs

.  Dry contacts for AUTO-purge external

start command and purge interrupt.

Digital Outputs

. Dry contacts for optional alarm or AUTO-

purge activation and acknowledgment.  Contacts rated for:

Maximum 3 amps @ 24 to 120VAC
Maximum 3 amps @ 24VDC
Maximum 0.5 amps @ 48VDC

Temperature Compensation Selection
