DCP200 Profile Controller & Recorder - Product Manual
Page 176 Specifications 51-52-25-150, Issue 1 – April 2009
Input resistance:
mV ranges : >10MΩ.
Voltage ranges: 47KΩ.
Curent ranges: 5Ω.
Input protection:
Voltage input: will withstand up to 5x input voltage overload without
damage or degradation of performance in either polarity.
Current input: will withstand 5x input current overload in reverse
direction and up to 1A in the normal direction.
Isolation:
Reinforced safety isolation from outputs and inputs (except to Digital
Input B).
Sensor Break
Detection:
Applicable for 4 to 20mA, 1 to 5V and 2 to 10V ranges only.
Control goes to the pre-set power value if Auxiliary Input is providing the
active setpoint source.

Free Operation:
Connection to contacts of external switch or relay:
Open = Logic High. Minimum contact resistance = 5KΩ,
Closed = Logic Low. Maximum contact resistance = 50Ω.
TTL levels:
2.0 to 24VDC = Logic High.
–0.6 to 0.8VDC = Logic Low.
Digital Input Sensitivity:
Edge Sensitive. Requires High-Low or Low-High transition to
change function.
Response Time:
Response within <0.25 second of signal state change.
Isolation:
Reinforced safety isolation from inputs and other outputs.
