(Key Parameters)
Parameter Category Specification for SCP461-11 S1
Model Yokogawa SCP461-11 S1
Type Digital Indicating Controller (Pressure Specific)
Input Signal Accepts signals from strain-gauge pressure sensors. The S1 suffix typically denotes a pre-configured input range, most commonly for sensors with a 0-10 MPa (0 to ~1450 psi) range. (Always verify the exact range on the unit's nameplate).
Pressure Sensor Excitation Provides +24V DC sensor excitation power supply (max 30mA) to power the strain-gauge sensor directly.
Display Dual 4-digit LED (Red for PV, Green for SV)
Control Output Relay Contact Output (1c / SPDT).
• Rating: 250V AC, 3A (resistive load) or 220V DC, 0.2A
This is used for ON/OFF control, e.g., to start/stop a motor or open/close a valve.
Auxiliary Output Transistor Output (often used for an alarm function)
• 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 for this variant).
Mounting DIN 96x96mm panel cutout.
Key Features • Sensor Break Detection
• Heater Break Alarm Function (optional)
• PV Zero/Span Adjustment
• High/Low Limit Alarm
• Auto/Manual Control Mode
