RCT202 - Programmable Digital Rate Indicator

The Radix RCT202 is a panel-mounted programmable digital rate indicator designed for industrial automation applications. It functions as an RPS/RPM/RPH indicator with a 4-digit, 7-segment 0.56-inch red LED display dedicated to rate indication.

The RCT202 is housed in an industry-standard 48 × 96 mm plug-in enclosure, enabling quick maintenance without disrupting rear terminal wiring. It operates from a universal 85–265 VAC/DC supply for flexible deployment in factory control panels.

Designed for high-speed measurement, the RCT202 processes input frequencies up to 5 kHz and provides rate indication accuracy of ±0.05% of the reading. It can display programmable units such as RPS, RPM and RPH.

Working Principle of Radix RCT202 Digital Rate Indicator

The RCT202 measures input pulse frequency to determine the corresponding rate. It can process frequencies up to 5 kHz from different pulse-generating sensors used for speed measurement.

A programmable base number and exponent provide automatic scaling, converting the incoming pulses into the required engineering units. This allows the displayed value to represent rates such as RPS, RPM or RPH.

The instrument accepts signals from proximity switches, photoelectric sensors, voltage pulses and electromagnetic pickups. A dedicated +12 VDC auxiliary supply is available from the terminal block for active industrial sensors.

The RCT202 provides rate indication accuracy of ±0.05% of the reading.

Types of RCT202 Digital Rate Indicator

The RCT202 is available in configurations for local rate indication, analogue retransmission and electromagnetic pickup inputs.

RCT202 Standard Indicator - Order Code: 2228

The Standard Indicator accepts standard universal inputs and provides digital rate indication.

It is suitable for monitoring rotational or linear speeds directly from a control panel.

RCT202 with Analog Output - Option 3

This configuration adds a 0–10 V DC analogue output for transmitting continuous rate data to central PLCs or factory SCADA systems.

RCT202 with Electromagnetic Pickup - Options 1 & 2

This version is configured to process 3-wire or 2-wire electromagnetic pickup signals.

It is intended for applications involving speed tracking of heavy machinery gears.

Why Choose Radix RCT202?

The RCT202 brings high-speed pulse measurement and programmable rate scaling into a compact panel-mounted instrument.

Its programmable base number and exponent allow pulse inputs to be converted into the required engineering units, while the dedicated rate display provides a direct indication of the measured value.

Different configurations allow the instrument to be selected for local speed monitoring, analogue transmission to a PLC or SCADA system, or measurement from electromagnetic pickups.

Supported sources include:

Proximity switches
Photoelectric sensors
Limit switch, Microswitch etc.
Voltage pulses
Electromagnetic pickups

For active industrial sensors, a dedicated +12 VDC auxiliary supply is available directly from the terminal block.

The Electromagnetic Pickup configuration supports both 3-wire and 2-wire pickup signals.

When to Use Which RCT202 Configuration?

Select the RCT202 Standard Indicator when the requirement is to display real-time machine speed locally using standard universal inputs.
Choose the RCT202 with Analog Output when continuous rate information needs to be transmitted to a PLC or factory SCADA system.
Specify the RCT202 with Electromagnetic Pickup when the application uses 2-wire or 3-wire electromagnetic pickup signals, such as heavy machinery gear monitoring.
Use the RCT202 with a 20–35 VDC supply when a low-voltage DC control-panel supply is required.
Choose the RCT202 when the application requires programmable rate units such as RPS, RPM or RPH.
