HIQUEL TCS & DGR Speed and Standstill Relays

HIQUEL TCS and DGR Speed and Standstill Relays are designed to monitor motor speed, direction, and shaft rotation in industrial machinery. These advanced relays detect overspeed, underspeed, or standstill conditions using pulse or analog input signals, providing essential protection and process control for conveyors, elevators, mixers, and rotating equipment.

🔧 Technical Highlights:

• Series Overview: TCS (tachometer control system) relays for overspeed/underspeed monitoring; DGR (direction and standstill) relays for rotation and zero-speed detection.
• Input Type: Supports proximity sensors, tachogenerators, or pulse encoders (NPN/PNP) for precise speed measurement.
• Speed Range: Adjustable from 0.1 Hz up to several kHz depending on model and application.
• Detection Functions: Overspeed, underspeed, standstill, and rotation direction (DGR models).
• Outputs: SPCO or DPCO relay contacts for fault signalling, alarm, or interlock functions.
• Response Time: Fast electronic detection with adjustable delay for stable performance.
• Supply Voltage: Universal 24–240 V AC/DC (model dependent).
• Indication: LED display for power, pulse detection, and relay status.
• Mounting: Compact DIN rail 35 mm housing for panel or machine integration.
• Compliance: CE and RoHS certified; conforms to IEC/EN 60255 for protective relays.

✅ Benefits:

• Prevents mechanical damage by detecting shaft stoppage or overspeed conditions.
• Improves process safety by verifying motor motion before enabling next operations.
• Monitors direction of rotation for safety interlocks and material flow control.
• Fast and reliable detection with minimal maintenance requirements.
• Designed for continuous operation in demanding industrial environments.

🚀 Applications:

• Conveyors, elevators, and cranes for motion verification.
• Pumps, mixers, and centrifuges for overspeed/underspeed detection.
• Fan and blower protection systems.
• Rotating machinery requiring zero-speed safety interlocks.
• Process automation and sequencing systems.

HIQUEL TCS and DGR relays provide precise, fast, and durable speed and standstill detection for rotating equipment, ensuring process safety, machine protection, and reliable control.

FAQs

• Q: What is the difference between the HIQUEL TCS and DGR relays?
  A: The TCS series monitors overspeed and underspeed using frequency or pulse input, while the DGR series detects direction and standstill conditions for rotational safety applications.
• Q: What type of sensors can be used with HIQUEL speed monitoring relays?
  A: They are compatible with inductive proximity sensors, Hall-effect sensors, or tachogenerators that provide frequency or pulse output signals.
