Dwyer SCZ10 - Manual (Page 18)

Setting accuracy: The same as indicating accuracy
Action:
ON/OFF action
Hysteresis: T/C and RTD input: 0.1 to 100.0°C (°F) [Factory adjusted as 1.0°C]
DC voltage and current input: 1 to 1000 [Factory adjusted as 10]
(Decimal point place follows the selection.)
Output: Open collector, 24Vdc @ 0.100A maximum.
Alarm (EVT) output action: Alarm action is selectable from below by front key operation.
One alarm is selectable from High limit, Low limit,
High/Low limits, High/Low limit range, Process high,
Process low, High limit w/standby, Low limit w/standby,
High/Low limits w/standby and No alarm action
[Factory adjusted as No alarm action]
Energized/Deenergized: Alarm (EVT) output Energized/Deenergized can be selected.
[Factory adjusted as Energized]
Energized Deenergized
Red (EVT) LED Lights Lights
Alarm output ON OFF
Alarm HOLD function selection: Once the alarm is activated, alarm output is remains
constant until power is turned off.
[Factory adjusted as: Alarm holding function Not used]
Loop break alarm (EVT) output is common with Alarm and optional Heater Burnout Alarm.
Detects heater burnout, sensor burnout, and abnormality at operation end.
Setting range: Loop break alarm time setting: 0 to 200 minutes
[Factory adjusted as 0 minutes]
Loop break alarm action span setting
Thermocouple and RTD input: 0 to 150°C (°F) or 0.0 to 150.0 °C (°F)
[Factory adjusted as 0°C
DC voltage and current input: 0 to 1500
(Decimal point place follows the selection.)
Output: Open Collector, 24Vdc @ 0.100A maxilmum.
Converter function: See Section 1, "Converter Function."
Insulation
• Dielectric strength Circuit insulation structure
* When controls output is non-
contact voltage of DC Current,
there is no isolation between
the control output and the
communications option.
Insulated resistance: 10M
Ω or greater @ 500 Vdc except as noted above.
Dielectric strength: 1.5kVac for 1 minute between input terminal and power
terminal.
Power consumption Approx. 6VA
Ambient temperature 0 to 50°C (32 to 122°F)
Ambient humidity
35 to 85%RH (Non condensing)
Weight Approx.150g (5.3 oz.)
