(Key Parameters)
Parameter Category Specification for SCP461-11
Model Yokogawa SCP461-11
Type Digital Indicating Controller (Pressure Specific)
Input Signal Accepts DC voltage/current signals from pressure sensors. Common ranges:
• 1-5V DC
• 4-20mA DC (with external 250Ω resistor)
Pressure Sensor Excitation Provides +24V DC sensor excitation power supply (max 30mA). This is a key feature for powering strain gauge-type pressure transmitters directly.
Display Dual 4-digit LED displays (Red for PV, Green for SV).
Control Output Relay Contact Output (1c / SPDT).
• Rating: 250V AC, 3A (resistive load) or 220V DC, 0.2A
Auxiliary Output Transistor Output (for driving SSR or alarm)
• Rating: 30V DC, 50mA max.
Control Action PID (Proportional-Integral-Derivative). Control action (direct/reverse) is selectable.
Power Supply 100-240V AC, 50/60Hz (Standard).
• Other versions available (e.g., 24V DC).
Mounting DIN 96x96mm panel cutout.
Case Plastic (UL94 V-0)
Ambient Operating Temp. 0 to 55°C (32 to 131°F)
