(Key Parameters)
Parameter Category Specification for CP461-50
Model Yokogawa CP461-50
Type Universal Digital Indicating Controller
Input Signal (Main) Voltage/Current Input (Selectable):
• DC Voltage: 1-5V, 0-5V, 0-10V
• DC Current: 4-20mA, 0-20mA (with internal 250Ω resistor)
Control Output DC Current Output (Analog):
• 4-20mA DC (Load resistance: 0-550Ω)
This is the primary control signal for driving devices like I/P converters or motorized actuators.
Auxiliary Output (Transistor) 1 point (for alarm or transmit output):
• Rating: 30V DC, 50mA max.
Display Dual 4-digit LED (Red for PV, Green for SV)
Control Action PID (Proportional-Integral-Derivative). Direct/Reverse action selectable.
Power Supply 100-240V AC, 50/60Hz (Standard).
Mounting DIN 96x96mm panel cutout.
Communication (Optional) An optional communication module (YS series) can be added for RS-485 Modbus communication.
Key Features • Sensor Break Detection (for TC and RTD inputs in other models, configurable for current/voltage)
• Two Alarm Outputs (can be assigned to various conditions: high/low limit, deviation, etc.)
• PV Zero/Span Adjustment
• Auto/Manual Control Mode with bumpless transfer
• Ramp/Soak Function (programming setpoint changes over time)
