Refer to PDC and Modbus Serial Communications Protocol manuals for details.
Rating: 2 Form C (SPDT); rated 3 A @ 30 VDC or 3 A @ 250 VAC resistive load; 1/14 HP @ 125/250 VAC inductive loads Deadband: 0-100% FS, user selectable High or Low Alarm: User may program any alarm for high or low Relay Operation: 1. Automatic (non-latching) 2. Latching 3. Pump alternation control Relay Reset: User selectable via front panel buttons or PC 1. Automatic reset only (non-latching) 2. Automatic + manual reset at any time (non-latching) 3. Manual reset only, at any time (latching) 4. Manual reset only after alarm condition has cleared (latching) Automatic Reset: Relays reset when input passes the reset point Manual Reset: Front panel button, MeterView, Modbus registers Time Delay: 0 to 199 seconds, on and off delays; programmable Fail-Safe Operation: Programmable, independent for each relay. Relay coils are energized in non-alarm condition. In case of power failure, relays will go to alarm state.
